ANA Profile & ENA Panel Explained: Antibodies, Normal Range & Autoimmune Diseases — India 2026
ANA प्रोफाइल / ENA पैनल: एंटीबॉडी, नॉर्मल रेंज और ऑटोइम्यून बीमारियाँ — पूरी जानकारी हिंदी में
If your ANA Screen test came back Positive, your Rheumatologist has likely ordered the next step: the ANA Profile or ENA (Extractable Nuclear Antigen) Panel. This confirmatory test identifies exactly which specific autoantibodies are present — and which autoimmune disease they point toward. This guide explains every parameter in simple English and Hindi.
यदि आपका ANA स्क्रीन टेस्ट पॉजिटिव आया है, तो डॉक्टर ने संभवतः ANA प्रोफाइल या ENA पैनल की सलाह दी है। यह गाइड हर एंटीबॉडी और उससे जुड़ी ऑटोइम्यून बीमारी को सरल हिंदी-अंग्रेजी में समझाती है।👁 Table of Contents / विषय सूची
What Is the ANA Profile / ENA Panel? / ANA प्रोफाइल क्या है?
There are two levels to autoimmune antibody testing in India. The ANA Screen is a "Yes/No" first-step test — it tells the doctor whether antinuclear antibodies are present at all, along with their titer (concentration) and staining pattern. See our ANA Screen complete guide for a full explanation of titers and patterns.
The ANA Profile (ENA Panel) is the confirmatory deep-dive. Once the screen is positive, the profile identifies exactly which specific autoantibodies are present — each one pointing toward a different autoimmune disease. In 2026, major Indian labs run an 11- to 17-parameter panel covering antibodies like Anti-dsDNA, Anti-Sm, Anti-Ro/SSA, Anti-La/SSB, Anti-RNP, Anti-Scl-70, and Anti-Jo-1, among others.
भारत में ऑटोइम्यून एंटीबॉडी टेस्टिंग के दो स्तर हैं। ANA स्क्रीन एक "हां/ना" पहला टेस्ट है। ANA प्रोफाइल (ENA पैनल) पुष्टिकरण टेस्ट है जो बताता है कि कौन से विशिष्ट ऑटोएंटीबॉडी मौजूद हैं — और प्रत्येक किस बीमारी की ओर इशारा करता है।When Is the ANA Profile Ordered? / इसे कब किया जाता है?
Rheumatologists in India order an ANA Profile / ENA Panel in the following situations:
भारत में रुमेटोलॉजिस्ट इन स्थितियों में ANA प्रोफाइल / ENA पैनल की सलाह देते हैं:The most common trigger. When the ANA Screen shows a titer of 1:160 or higher, the profile is essential to identify which specific antibody is responsible. Low-titer positives (1:40, 1:80) may be observed clinically before ordering the profile.
Young women (20–45) with butterfly facial rash (malar rash), photosensitivity, joint pain, and fatigue — the classic Lupus presentation in India. Anti-dsDNA and Anti-Sm are the key antibodies being sought.
Persistent dry eyes, dry mouth, and fatigue — especially in middle-aged women. Anti-Ro/SSA and Anti-La/SSB are the specific markers being checked. Increasingly recognised in India as an underdiagnosed condition.
Progressive skin tightening, Raynaud's phenomenon (fingers turning white/blue in cold), and breathlessness prompt testing for Anti-Scl-70 to confirm Scleroderma (Systemic Sclerosis).
Proximal muscle weakness (difficulty climbing stairs, raising arms), elevated CPK levels, and fatigue suggest inflammatory myopathy. Anti-Jo-1 and other myositis-specific antibodies confirm the diagnosis.
When a patient shows features of multiple autoimmune diseases simultaneously — some Lupus features, some Scleroderma features, some myositis features. Anti-RNP positivity classically points toward Mixed Connective Tissue Disease (MCTD).
Specific Antibodies & Diseases They Pinpoint / एंटीबॉडी और संबंधित बीमारियाँ
Most parameters in the ANA Profile report a Qualitative result — either Negative or Positive (with some labs also providing a Ratio or Index value). The critical column is which specific antibody is positive and what clinical significance it carries.
ANA प्रोफाइल के अधिकांश पैरामीटर एक क्वालिटेटिव परिणाम देते हैं — नेगेटिव या पॉजिटिव। महत्वपूर्ण यह है कि कौन-सी एंटीबॉडी पॉजिटिव है और उसका क्लिनिकल महत्व क्या है।| Antibody / एंटीबॉडी | Clinical Significance | Primary Disease / मुख्य बीमारी | Additional Notes |
|---|---|---|---|
| Anti-dsDNA डबल-स्ट्रैंडेड DNA |
Highly specific. Rising levels may indicate active disease or kidney involvement (lupus nephritis). | SLE (Lupus) ल्यूपस |
Used to monitor Lupus disease activity over time, not just diagnosis. |
| Anti-Sm स्मिथ एंटीबॉडी |
Highly specific for Lupus — rarely positive outside SLE. Low sensitivity but very high specificity. | SLE (Lupus) ल्यूपस |
Positive Anti-Sm alone can confirm Lupus diagnosis in clinical context. |
| Anti-Ro / SSA एंटी-Ro |
Causes dry eyes and mouth. Critically important in pregnant women — can cross placenta and affect foetal heart. | Sjogren's Syndrome, SLE जोग्रेन सिंड्रोम, ल्यूपस |
Checked routinely in all pregnant women with Lupus for foetal monitoring. |
| Anti-La / SSB एंटी-La |
Almost always tested alongside Anti-Ro. More specific for primary Sjogren's than Anti-Ro alone. | Sjogren's Syndrome जोग्रेन सिंड्रोम |
Rarely positive without Anti-Ro also being positive. |
| Anti-RNP राइबोन्यूक्लियोप्रोटीन |
High-titer positivity is the defining antibody of Mixed Connective Tissue Disease. Also seen in Lupus. | MCTD (Mixed CTD) मिश्रित संयोजी ऊतक रोग |
MCTD = overlap of Lupus + Scleroderma + Myositis features. |
| Anti-Scl-70 टोपोइज़ोमेरेज़ I |
Indicates diffuse skin thickening and high risk of internal organ fibrosis (lungs, kidneys, heart). | Scleroderma / Systemic Sclerosis स्क्लेरोडर्मा |
Associated with severe, rapidly progressing form of Scleroderma. |
| Anti-Jo-1 एंटी-Jo-1 |
Marker of inflammatory muscle disease. Often associated with lung involvement (interstitial lung disease). | Polymyositis / Dermatomyositis मायोसिटिस |
Part of the "anti-synthetase syndrome" — muscle + lung + arthritis triad. |
| Anti-Centromere (ACA) एंटी-सेंट्रोमेयर |
Associated with limited skin disease and Raynaud's phenomenon. Better prognosis than Anti-Scl-70. | Limited Scleroderma (CREST Syndrome) लिमिटेड स्क्लेरोडर्मा |
More slowly progressive than diffuse Scleroderma. |
| Anti-Histone | Specific for drug-induced lupus — caused by certain long-term medications (procainamide, hydralazine, isoniazid). | Drug-Induced Lupus दवा-प्रेरित ल्यूपस |
Symptoms usually resolve once the causative drug is stopped. |
How to Read Your ANA Profile Report / रिपोर्ट कैसे पढ़ें
Understanding your report requires looking at several things together — no single positive result tells the complete story:
रिपोर्ट समझने के लिए कई चीज़ें एक साथ देखनी होती हैं — कोई एक पॉजिटिव परिणाम पूरी कहानी नहीं बताता:List every parameter marked Positive. The combination matters — Positive Anti-Ro alone vs Positive Anti-Ro + Anti-dsDNA + Anti-Sm together points to very different clinical scenarios. Share the full list with your Rheumatologist, not just one value.
Some labs (SRL, Metropolis) also report a numeric index alongside Negative/Positive. A ratio of 1.0–2.0 is weakly positive; above 3.0 is strongly positive. Higher ratios for disease-specific antibodies like Anti-dsDNA carry more clinical weight.
A positive Anti-Scl-70 in a patient with no skin changes and no Raynaud's is less significant than the same result in a patient actively experiencing skin tightening. The laboratory finding must match the clinical picture for a diagnosis to be made.
For patients with confirmed Lupus, Anti-dsDNA levels are monitored over time — rising levels can signal an upcoming disease flare before symptoms appear. Always use the same lab for serial tracking to ensure comparability.

Test Preparation / टेस्ट की तैयारी
-
Fasting NOT required
No fasting is required for the ANA Profile or ENA Panel. You can give your blood sample at any time of the day. If the ANA Profile is being ordered alongside a fasting panel (Lipid Profile, Blood Sugar, LFT), follow the fasting instructions for those tests — the thyroid and ANA components themselves do not require fasting.
ANA प्रोफाइल या ENA पैनल के लिए उपवास (फास्टिंग) की आवश्यकता नहीं है। यदि यह लिपिड प्रोफाइल जैसे अन्य टेस्ट के साथ है, तो उन टेस्ट के निर्देशों का पालन करें। -
Inform your lab about all current medications
Certain drugs — particularly prolonged use of hydralazine, procainamide, isoniazid, minocycline, and some anticonvulsants — can cause drug-induced lupus and produce a positive Anti-Histone result. Always inform both your doctor and the lab about your current medication list so results can be interpreted correctly.
अपनी सभी मौजूदा दवाओं के बारे में डॉक्टर और लैब को बताएं। कुछ दवाएं (जैसे INH/आइसोनियाज़िड) Anti-Histone को गलत तरीके से पॉजिटिव दिखा सकती हैं। -
Use the same lab for serial monitoring
If you are already diagnosed with Lupus and are being monitored with Anti-dsDNA levels over time, always use the same laboratory. Different labs use different assay platforms — Anti-dsDNA values are not directly comparable across labs, and a numerical change at the same lab is the only reliable signal of disease activity change.
यदि Lupus की निगरानी के लिए Anti-dsDNA बार-बार किया जा रहा है, हमेशा एक ही लैब का उपयोग करें। विभिन्न लैब के मान सीधे तुलनीय नहीं होते। -
Bring previous reports to your Rheumatologist appointment
The ANA Profile is most meaningful when reviewed alongside your ANA Screen titer and pattern, clinical history, CBC, kidney function, and any prior autoimmune tests. Bring all previous reports — including the original ANA Screen that prompted this test — to ensure your Rheumatologist has the complete picture.
रुमेटोलॉजिस्ट के पास जाते समय सभी पुरानी रिपोर्टें लेकर जाएं — ANA स्क्रीन, CBC, किडनी फंक्शन, और पिछले सभी ऑटोइम्यून टेस्ट सहित।

These tests are commonly ordered alongside or after an ANA Profile in India:
ANA प्रोफाइल के साथ या बाद में ये जांचें अक्सर करवाई जाती हैं:Frequently Asked Questions / अक्सर पूछे जाने वाले सवाल
The ANA Screen (done by IFA method) is a first-step "Yes/No" test — it detects whether antinuclear antibodies are present, their concentration (titer), and fluorescence pattern. It does not tell you which specific antibody is present. The ANA Profile (ENA Panel) is the second-step confirmatory test — it identifies exactly which specific autoantibodies (Anti-dsDNA, Anti-Sm, Anti-Ro, Anti-La, etc.) are present. The profile is typically ordered only after a positive ANA Screen result, usually with a titer of 1:160 or higher.
उत्तर: ANA स्क्रीन "हां/ना" पहला कदम है — बताता है कि एंटीबॉडी हैं या नहीं। ANA प्रोफाइल दूसरा कदम है — बताता है कि ठीक कौन-सी एंटीबॉडी है।Anti-dsDNA is highly specific for Lupus (SLE) — meaning it very rarely appears in other conditions. However, a positive result alone does not confirm the diagnosis. Lupus is diagnosed using the ACR/EULAR classification criteria, which requires a combination of clinical features (butterfly rash, kidney involvement, blood count changes) plus laboratory findings. Your Rheumatologist will assess whether you meet the criteria. A positive Anti-dsDNA is a strong signal — but it must be matched with symptoms and other findings.
उत्तर: Anti-dsDNA Lupus के लिए बहुत विशिष्ट है लेकिन यकीनी नहीं। Lupus का निदान लक्षणों और कई टेस्ट को मिलाकर ACR/EULAR मानदंडों के आधार पर होता है।No — fasting is not required for the ANA Profile or any of the specific antibody parameters within the ENA Panel. You can give your blood sample at any time of day. If the ANA Profile is being combined with fasting tests (Lipid Profile, Fasting Blood Sugar, LFT), fast only for those add-on components. The ANA itself does not require fasting.
उत्तर: नहीं — ANA प्रोफाइल / ENA पैनल के लिए उपवास आवश्यक नहीं। दिन के किसी भी समय ब्लड सैंपल दे सकते हैं।For most disease-specific antibodies — particularly Anti-dsDNA in Lupus — levels can decrease with effective immunosuppressive treatment (hydroxychloroquine, steroids, mycophenolate). Anti-dsDNA is actively monitored over time to track disease activity. However, antibodies like Anti-Sm or Anti-Ro tend to remain positive even in remission and are not as useful for tracking disease activity. Your Rheumatologist will decide which parameters to monitor and at what frequency.
उत्तर: Anti-dsDNA इलाज से कम हो सकती है और बीमारी की सक्रियता को ट्रैक करने के लिए मॉनिटर की जाती है। Anti-Sm जैसी कुछ एंटीबॉडी रिमिशन में भी पॉजिटिव रहती हैं।Anti-Ro/SSA antibodies are critically important in pregnant women with Lupus or Sjogren's Syndrome because they can cross the placenta and affect the developing baby. The most serious risk is neonatal lupus and congenital heart block — a condition where the baby's heart develops an abnormal rhythm in the womb. Women with known Anti-Ro positivity are monitored with foetal echocardiography (heart ultrasound) from around 16–18 weeks of pregnancy. This is a planned, manageable risk — not an automatic cause for alarm — when monitored properly by a high-risk obstetrics team.
उत्तर: Anti-Ro/SSA एंटीबॉडी प्लेसेंटा पार कर सकती है और नवजात ल्यूपस या जन्मजात हार्ट ब्लॉक का कारण बन सकती है। पॉजिटिव महिलाओं में गर्भावस्था के दौरान फीटल इको-कार्डियोग्राफी से निगरानी की जाती है।A low-level positive on the ANA Screen (1:40 or 1:80) can appear in 5–15% of healthy adults — this is especially common in older women and is usually not clinically significant. However, disease-specific ANA Profile parameters — particularly Anti-dsDNA, Anti-Sm, Anti-Scl-70, and Anti-Jo-1 — are very rarely positive in healthy individuals without an underlying autoimmune condition. A positive disease-specific parameter should always be evaluated by a Rheumatologist in context of clinical symptoms, even if mild.
उत्तर: ANA स्क्रीन 5-15% स्वस्थ लोगों में हल्का पॉजिटिव आ सकता है। लेकिन ANA प्रोफाइल के रोग-विशिष्ट पैरामीटर (Anti-dsDNA, Anti-Sm आदि) स्वस्थ लोगों में बहुत कम पॉजिटिव होते हैं।- Mayo Clinic: ANA (Antinuclear Antibody) Test
