What Is an ANA IFA Reflex to ANA Immunoblot Test?
The ANA IFA reflex to ANA Immunoblot test is a two-step blood test used to detect antinuclear antibodies (proteins the immune system produces that may attack the body's own cells). A doctor typically orders this test when a patient shows symptoms that suggest an autoimmune condition. It is also known as the Antinuclear Antibody Reflex Panel or ANA Screen IFA with Reflex to ENA Panel. A small serum sample drawn from a vein is used for both steps.
What Does an ANA IFA Reflex to ANA Immunoblot Test Measure?
This test works in two stages. The first stage screens for the presence of antinuclear antibodies; the second stage identifies exactly which antibodies are present if the screen is positive.
The table below lists the key antigens examined in the immunoblot step.
| Antigen | What It May Indicate |
|---|---|
| Anti-Sm (Smith) | Highly specific for systemic lupus erythematosus (SLE) |
| Anti-RNP (Ribonucleoprotein) | Associated with mixed connective tissue disease |
| Anti-SS-A/Ro and Anti-SS-B/La | Linked to Sjögren's syndrome (causes dry eyes and mouth) |
| Anti-Scl-70 (Topoisomerase I) | Associated with scleroderma (skin and tissue hardening) |
| Anti-Jo-1 | Linked to polymyositis and dermatomyositis (inflammatory muscle diseases) |
| Anti-dsDNA | Specific for lupus (SLE) |
| Anti-CENP-B (Centromere) | Associated with limited scleroderma |
| Additional antigens (up to 18 total) | Nucleosome, histone, ribosomal P-protein, AMA M2, Ro-52, PM/Scl, PCNA, Ku, Mi-2, DFS70 |
Why Is an ANA IFA Reflex to ANA Immunoblot Test Done?
Doctors order this test when a patient's symptoms point to a possible autoimmune disorder. The ANA IFA reflex to ANA Immunoblot test procedure helps both screen and confirm the presence of specific autoantibodies in a single, efficient workflow.

The following symptoms are among the most frequent reasons a doctor may request this test.
- Persistent joint pain or swelling
- Unexplained fatigue lasting several weeks
- Skin rashes, particularly a butterfly-shaped rash on the face

How to Prepare and What to Expect
The ANA IFA reflex to ANA Immunoblot test requires minimal preparation. A brief overview of what to do before and during the test is provided below.
Do You Need to Fast?
No, fasting is not required before this test. You can eat and drink normally on the day of your sample collection.
Practical Tips Before Your Test
A few simple steps before your appointment will help ensure accurate results.
- Bring a detailed clinical history, including your symptoms, previous test results, and family history, as this is required for the test.
- Inform your doctor about all medications, vitamins, and supplements you currently take, as some (such as hydralazine, procainamide, isoniazid, and minocycline) may affect results.
- Let your doctor know about any recent or current infections.
- Drink water before your appointment; staying well-hydrated makes the blood draw easier.
- Wear a loose-sleeved top so the phlebotomist can access your arm easily.
Step-by-Step Procedure
Here is what to expect during the sample collection for the ANA IFA reflex to ANA Immunoblot test procedure.
- A trained phlebotomist (blood collection specialist) will ask you to sit comfortably and rest your arm on a flat surface.
- The area on your inner arm, near the elbow, is cleaned with an antiseptic wipe.
- A tourniquet (a soft band) is placed around your upper arm to make the vein more visible.
- A small needle is inserted into the vein and a serum sample of approximately 3 ml is drawn into a collection tube.
- The needle is removed, and a small cotton pad is pressed over the site. The entire process usually takes less than five minutes.
- The labelled sample is stored at 2 to 8°C and sent to the NABL-accredited laboratory. If the ANA IFA screen returns positive, the immunoblot step is automatically performed on the same sample.
Factors That Can Affect Accuracy
Several factors can influence your test results.
- Certain medications, including hydralazine, procainamide, isoniazid, and minocycline
- Recent viral illnesses or ongoing chronic infections
- Age (positive ANA results are more common in older adults, even without disease)
- Improper sample handling or storage
- High levels of physical or emotional stress around the time of the test
Understanding Your ANA IFA Reflex to ANA Immunoblot Test Results
Results from this test must always be reviewed by your doctor alongside your symptoms, medical history, and any other investigations. The table below shows general reference ranges.
| Parameter | Normal / Expected Result |
|---|---|
| ANA IFA Screen | Negative |
| ANA Titre | Less than 1:80 (negative) |
| Individual Immunoblot Antigens | Negative (qualitative) |
A titre of 1:80 or below is generally considered negative. Titres above 1:80 may be consistent with an autoimmune condition, though results must be read in full clinical context. A positive ANA IFA triggers the immunoblot step automatically; specific antigen results then help narrow down the possible diagnosis.
A negative result makes an autoimmune disorder less likely, but it does not completely rule one out.
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how results are interpreted.
Up to 15% of completely healthy individuals may show a positive ANA result. This rate rises with age, particularly in women over 40, where positive results may be seen in 15% to 20% of those without any diagnosed condition. A positive ANA following a recent viral illness or during treatment with certain medications does not automatically indicate autoimmune disease.
How to Maintain Healthy Levels
These are general wellness tips to support your immune system.
- Eat a balanced diet with plenty of vegetables, whole grains, and lean proteins to support overall immune function.
- Engage in regular moderate exercise, as physical activity helps regulate the immune response.
- Practise stress management techniques such as adequate sleep, relaxation, and avoiding overexertion.

Frequently Asked Questions
The ANA IFA (Indirect Immunofluorescence Assay) is the first-line screen that detects whether antinuclear antibodies are present in your blood. The ANA Immunoblot is performed only if the IFA is positive, and it identifies which specific autoantibodies are present, helping doctors narrow down a possible diagnosis.
In the ANA IFA reflex to ANA Immunoblot test, the immunoblot step runs automatically only when the IFA screen is positive. This approach avoids unnecessary testing, saves time, and ensures appropriate follow-up is done on the same sample without requiring a repeat blood draw.
Yes. Up to 15% of healthy individuals can show a positive ANA result. A positive result on its own does not confirm an autoimmune disease. Your doctor will consider the titre level, the staining pattern, immunoblot findings, and your symptoms together before reaching any conclusion.
Do not stop any medication without first speaking to your doctor. However, certain medicines such as isoniazid, hydralazine, and minocycline can affect results. Your doctor will advise whether any adjustments are needed before the test.
Not entirely. A negative result makes an autoimmune disorder less likely, but some autoimmune conditions can still be present even when the ANA screen is negative. Your doctor will review your results alongside your clinical picture and may order further tests if needed.
Clinical history helps the laboratory and your doctor interpret the results accurately. Symptoms, existing conditions, medications, and family history all provide important context. Without this information, even an experienced clinician may find isolated test results difficult to interpret correctly.
The ANA IFA reflex to ANA Immunoblot report is typically delivered within 1 day of sample collection at Lupin Diagnostics. Your report will be sent digitally to your registered email address or WhatsApp number.
