In short
- The assessment looks for autoimmune connective tissue diseases such as lupus or scleroderma when symptoms suggest them.
- A positive ANA blood test is common in healthy people and is not, by itself, a diagnosis; results must be read with your symptoms.
- Diagnosis is clinical and supported by tests; further, more specific antibody tests may follow an abnormal result.
- A normal result is reassuring but does not always completely rule out disease, and you may need review if symptoms change.
A plain-English summary. The detail — including risks and recovery — is below.

What is a connective tissue disease assessment?
Connective tissue diseases are autoimmune conditions in which the immune system attacks the body's own tissues. They include systemic lupus erythematosus (lupus), scleroderma (systemic sclerosis), Sjogren's syndrome and others. They can cause varied symptoms such as joint pain, rashes, fatigue, dryness, and colour changes in the fingers in the cold (Raynaud's phenomenon).
The assessment combines a careful history and examination with blood tests, most commonly a test for antinuclear antibodies (ANA) and, where appropriate, more specific antibody tests. The aim is to decide whether your symptoms fit an autoimmune connective tissue disease, and if so which one, or to provide reassurance when they do not.
It is essential to understand what the blood tests can and cannot do. A positive ANA is common in healthy people and is not, on its own, a diagnosis; it has high sensitivity but low specificity, so many positive results are not due to disease. Equally, results must always be read alongside your symptoms. The diagnosis is clinical, supported by tests, not made by a single number.
This guide explains what the assessment involves, what the results mean, and what good follow-up looks like.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
Clinical history and examination
A detailed review of symptoms (such as joint pain, rashes, dryness, Raynaud's and fatigue) and an examination, which guide which tests are useful and how to interpret them.
Antinuclear antibody (ANA) test
A common screening blood test for autoimmune connective tissue disease. It is sensitive but not specific, so a positive result is common and needs to be interpreted carefully...
More specific antibody tests
If the picture warrants it, further tests such as anti-dsDNA (linked to lupus) or extractable nuclear antigen (ENA) antibodies, and scleroderma-associated antibodies, help...
Supporting blood and urine tests
Tests such as full blood count, kidney function, inflammation markers and urine checks help assess whether organs are affected and how active any disease is.
Preparing for your test
- Note your symptoms and when they started, including joint pain, rashes, dryness of eyes or mouth, fatigue and colour changes in the fingers.
- Note anything that triggers symptoms, such as cold or sunlight, and how they affect daily life.
- List your medicines, as some can affect autoantibody tests or cause lupus-like symptoms.
- Note any family history of autoimmune or connective tissue conditions.
- Bring previous blood results or letters, especially any earlier ANA result, to avoid repeating tests.
- Tell the clinician if you might be pregnant or are planning pregnancy, as this affects some conditions and medicines.
- Expect results to be interpreted alongside your symptoms rather than as a single yes-or-no answer.
What happens
At the appointment, the specialist takes a detailed history and examines you, looking for features of the various connective tissue diseases. This clinical picture decides which blood tests are worth doing and how they should be read.
Blood is taken for tests such as ANA and, where appropriate, more specific antibodies and tests of how organs are working. A urine sample may be checked. If you have Raynaud's, your clinician may examine the small blood vessels at the base of your nails.
The assessment is usually led by a rheumatologist. Results come back over several days to a couple of weeks and are interpreted together with your symptoms. You should then receive an explanation and a plan, whether that is a diagnosis, further tests, monitoring, or reassurance.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Autoantibody testing is the wrong test when done without relevant symptoms, because a positive result is common and can cause harm through false alarm.
- A single ANA result is not a substitute for clinical assessment and should not be used alone to diagnose or exclude disease.
- This assessment is not the right route for symptoms needing urgent care, such as severe breathlessness or kidney problems, which need immediate attention.
- Broad antibody panels without a clinical reason are not appropriate.
Delay or rearrange if…
- Treat urgently first if there are features of severe, active disease, such as breathing, kidney or neurological problems.
- Some medicines can affect results or cause lupus-like symptoms, which may need reviewing first.
- Pregnancy or pregnancy plans should be flagged, as they affect interpretation and management.
- Gathering previous results, including earlier ANA tests, can avoid repeating tests.
Alternatives to discuss
- No testing if there are no relevant symptoms.
- NHS pathway through your GP, with referral when warranted.
- Clinical review and watchful monitoring rather than immediate broad testing.
- Targeted tests guided by symptoms rather than a wide panel.
- Management of specific problems, such as Raynaud's, in their own right.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Helps decide whether symptoms are due to an autoimmune connective tissue disease
- Can point towards a specific condition, such as lupus or scleroderma, when antibodies and symptoms fit
- Allows early treatment and monitoring where a condition is found
- Can provide reassurance when symptoms are not due to these diseases
- Identifies related problems, such as Raynaud's or organ involvement, that may need attention
Risks & complications
- A positive ANA that turns out not to be due to disease, causing worry and sometimes further tests
- Results that are unclear or borderline and need repeating or reviewing over time
- Minor bruising or discomfort from the blood test
- A normal result that does not fully explain ongoing symptoms
- Anxiety from an uncertain or evolving diagnosis
- Over-investigation if tests are done without a clear clinical reason
- A condition being labelled too early or too late as the picture develops
- Needing referral to other specialists for organ involvement
- A serious, active connective tissue disease affecting organs, needing prompt treatment
- Distress if a significant diagnosis is identified
The biggest pitfall is misreading a positive ANA, which is common in healthy people, as proof of disease, or treating a single test as a diagnosis. Ask your clinician how the results fit your symptoms, what a positive or normal result actually means for you, and what would happen next if the picture is unclear.
Published figures to discuss
These tests are sensitive but not specific, so their meaning depends heavily on how likely disease is before testing. A positive ANA is common in the general population, so in people with few symptoms most positives do not reflect disease (false positives), while a normal result does not always exclude disease early on. Because reported figures vary by laboratory method and population, this guide describes test accuracy in cautious, qualitative terms rather than fixed percentages.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Positive ANA test in otherwise healthy people | Low-titre positives are common; estimates around 10 to 20% are reported in healthy populations | A positive antibody test is not a diagnosis on its own; the symptoms, examination and organ checks matter more than the number in isolation. | NHS — Lupusnhs.ukPublished figure |
| Interstitial lung disease in systemic sclerosis-spectrum disease | Reported in roughly 40 to 50% of people with systemic sclerosis, with severity varying widely | Breathlessness, cough, abnormal lung function or reduced exercise tolerance should trigger proper lung assessment rather than reassurance. | NHS — Lupusnhs.ukPublished figure |
| Kidney inflammation in systemic lupus erythematosus | Around 30 to 50% of people with lupus develop kidney involvement in many series | Urine testing and kidney blood tests are essential because early kidney disease may cause few symptoms. | NHS — Lupusnhs.ukPublished figure |
| Raynaud's phenomenon being secondary rather than primary | A minority, but risk rises with abnormal nailfold capillaries, ulcers or disease-specific antibodies | Finger ulcers, puffy fingers, asymmetry or systemic symptoms should prompt specialist assessment. | NHS — Lupusnhs.ukSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from the assessment. Here, this means what happens afterwards: waiting for results, how they are interpreted with your symptoms, and what follow-up or monitoring is arranged.
- Waiting several days to a couple of weeks for blood results
- Results being explained in the context of your symptoms rather than alone
- Sometimes needing repeat or further tests to clarify the picture
- A small bruise at the blood-test site that settles quickly
Aftercare
- Read your clinic letter and note the results, plan and any follow-up.
- Attend any further tests or specialist appointments arranged.
- If a condition is found, take any treatment as prescribed and keep monitoring appointments.
- If results are normal but symptoms continue, note any changes to discuss at review.
- Follow advice for related problems, such as keeping warm to manage Raynaud's.
- Tell your team if symptoms change or new ones appear, as this can alter the picture.
- Keep your GP informed so prescriptions and monitoring are joined up.
- Clinic letter and results received and read
- Any further tests or appointments booked
- Understanding of what your result does and does not mean
- Plan for any related symptoms (such as Raynaud's)
- Monitoring arrangements if a condition is found
- List of changes or new symptoms to report
- Named contact for the clinic saved
⚠ Get urgent help if…
- Severe breathlessness, chest pain or coughing up blood (call 999)
- New severe headache, confusion, seizures, or weakness or numbness on one side (seek urgent help)
- Marked swelling of the legs, frothy urine or a sharp drop in how much you pass (possible kidney involvement)
- Fingers or toes that turn white or blue and stay painful, cold or develop sores
- A high fever or feeling very unwell, especially if you take immune-suppressing medicines
- A widespread or rapidly worsening rash, especially after sun exposure
- Symptoms that are escalating quickly rather than slowly evolving
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A useful outcome of the assessment is a clear answer about whether your symptoms are due to an autoimmune connective tissue disease, and if so which one, so the right treatment and monitoring can start. Where antibodies and symptoms point clearly to a condition, the diagnosis may be confident; in other cases the picture is less certain.
Results must always be read with your symptoms. A positive ANA on its own does not mean you have a disease, and a normal result is reassuring but does not always completely exclude one, particularly early on. Where things are unclear, the specialist may keep you under review rather than label you prematurely.
Blood results reflect a moment in time, and autoimmune connective tissue diseases can evolve. A normal or borderline result now does not guarantee the picture will stay the same, so repeat testing or review may be needed if symptoms change. Where a condition is diagnosed, monitoring continues long term to track activity and any organ involvement.
Related tests, treatments or support
A connective tissue disease assessment often goes alongside checks for related problems, such as Raynaud's phenomenon, dry eyes and mouth, or organ involvement, and may involve other specialists. It may also be considered together with a hypermobility assessment when the cause of joint and tissue symptoms is being worked out.
Follow-up & long-term care
After the assessment, a clinic letter summarises the results and plan for you and your GP. Follow-up depends on the findings: a confirmed condition leads to treatment and regular monitoring; an unclear picture may be reviewed over time; and normal results with settling symptoms may need no further specialist input, with advice on when to seek review.
- Regular monitoring of disease activity and organ function where a condition is found
- Ongoing review if results are borderline or the picture is evolving
- Management of related problems such as Raynaud's
- Keeping medicines and any required blood-test monitoring up to date
- Knowing which new symptoms should prompt earlier review
Repeat, follow-on and what comes next
- Results may need repeating, as autoimmune conditions can evolve over time.
- A diagnosis may become clearer, change, or be revised as the picture develops.
- Borderline or unexplained results are often kept under review rather than labelled immediately.
- Further or more specific tests may be needed if symptoms change.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- Clear interpretation of results alongside your symptoms, with a clinic letter to you and your GP.
- A defined plan for treatment, further tests, monitoring or reassurance.
- Sensible review arrangements where the picture is unclear.
- Management of related problems such as Raynaud's and onward referral for organ involvement.
- A named contact and clear advice on which symptoms need urgent attention.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Length and seniority of the specialist's appointment
- Which blood tests are needed, including more specific antibody panels
- Any additional tests, such as urine checks, imaging or nailfold examination
- Whether more than one appointment or ongoing monitoring is needed
- Input from other specialists if organs are involved
- Follow-up reviews and clinic letters
- Which specialist will assess you and their experience
- Which blood and other tests are included
- Whether repeat or follow-up testing is included
- What the clinic letter and follow-up arrangements cover
- Whether onward referral for organ involvement is included or extra
- How results will be shared with your NHS GP
- What happens if results are inconclusive or further tests are needed
On the NHS? Connective tissue disease assessment is available on the NHS when symptoms warrant it, usually after a GP referral; private care may be used for a faster assessment but follows the same principles of interpreting tests alongside symptoms.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Treating a positive ANA as a diagnosis on its own.
- Testing without a clear clinical reason and then over-investigating a false positive.
- Not explaining what a positive or normal result actually means for the individual.
- No plan for what happens if results are unclear or borderline.
- Not discussing how results will be shared and who will act on them.
Marketing red flags
- Offering broad autoantibody panels as a general health check without symptoms.
- Implying a single blood test can confirm or exclude lupus or scleroderma by itself.
- Promising certainty from results that are often uncertain.
- Selling repeated testing without a clear clinical reason.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- Do my symptoms suggest a connective tissue disease, and which ones are you considering?
- What will a positive or a normal result actually mean for me?
- Which specific tests are you doing, and why?
- What happens next if the result is unclear or borderline?
- How will any related problems, such as Raynaud's or organ involvement, be checked?
- When should I be reviewed, and what symptoms should prompt me to come back sooner?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
