Description
Antinuclear Antibodies (ANA)
Sample Type:Serum
Tests Included:
Antinuclear Antibodies measurement.
Sample Required:
Blood sample.
Test Time:
Results are typically available within a few days.
Test Range Values:
Results are reported as a titer (e.g., 1:40, 1:80). Higher titers indicate a higher concentration of antinuclear antibodies.
What is the test?
This test detects antinuclear antibodies that target the nucleus of cells. Elevated levels may indicate autoimmune diseases, such as lupus or rheumatoid arthritis.
Test Procedure:
A blood sample is drawn from a vein, and the presence and pattern of antinuclear antibodies are examined in the laboratory.
When to ta
ke the test:
When a healthcare provider suspects an autoimmune disorder, especially if a patient presents symptoms like joint pain, skin rashes, or fatigue.
Who should take the test:

Precautions for exceptional cases (pregnancy, etc.):
The test is generally safe for pregnant individuals, but it’s essential to inform healthcare providers about pregnancy to ensure appropriate interpretation.
Frequently Asked Questions (FAQs) for Antinuclear Antibodies (ANA) Test:
Q1: What conditions are associated with a positive ANA test?
A: ANA positivity can be linked to autoimmune disorders like lupus, rheumatoid arthritis, or Sjogren’s syndrome.
Q2: Can medications affect ANA test results?
A: Yes, certain medications, such as some blood pressure medications and anticonvulsants, may cause a false-positive ANA result.
Q3: Is a positive ANA test definitive for an autoimmune disease?
A: No, a positive ANA test alone does not diagnose a specific autoimmune disease. Further testing and clinical evaluation are needed.
Q4: Can ANA levels fluctuate over time?
A: Yes, ANA levels can vary, and a positive result may not always indicate an active autoimmune disease.
Q5: Are there lifestyle changes that can impact ANA levels?
A:While lifestyle changes may not directly affect ANA levels, managing stress and maintaining a healthy lifestyle can contribute to overall well-being.
