An antinuclear antibodies (ANA) 17 blot test, also known as an ANA-17 Pro test, is a blood test used to detect autoantibodies that target specific antigens within the cell nucleus, helping diagnose and differentiate between various autoimmune diseases.
Here’s a more detailed explanation:
What it is:
ANA Blot 17 antigens test:
This test detects the presence of antinuclear antibodies (ANAs) in the blood, which are autoantibodies that the body produces that attack its own healthy cells.
Purpose:
It helps diagnose and differentiate between various autoimmune diseases, including systemic lupus erythematosus (SLE), Sjogren’s syndrome, mixed connective tissue disease (MCTD), scleroderma, and others.
How it works:
The test uses a strip with 17 specific antigens, allowing for the identification of antibodies against these antigens, which can help determine the type of autoimmune condition.
Antigens:
The test detects antibodies against antigens like dsDNA, nucleosomes, histones, rib, SS-A, Ro-52, Scl-70, and PM-Scl.
Interpretation:
A positive result indicates the presence of ANAs, suggesting a possible autoimmune disease.
Why it’s done:
Diagnosis:
To help diagnose autoimmune diseases when symptoms like joint pain, fatigue, fever, and skin rashes are present.
Confirmation:
To confirm a diagnosis after a preliminary ANA screening test (like ANA IFA or ELISA) is positive.
Differentiation:
To help differentiate between different autoimmune conditions based on the specific antibodies detected.
Important Considerations:
Positive Results:
A positive ANA test result doesn’t necessarily mean you have an autoimmune disease, as many healthy individuals also have ANAs in their blood.
Further Testing:
A positive ANA test often requires further testing to determine the specific type of autoimmune disease and the severity of the condition.

An antithyroid microsomal antibody (AMA) test, also known as a thyroid peroxidase test, measures the level of antibodies in the blood that attack thyroid peroxidase.
Purpose
To confirm the cause of thyroid problems
To determine if an autoimmune disorder is damaging the thyroid
When to get tested
If you are experiencing symptoms like sweating, fatigue, sudden weight gain or loss, hair loss, anxiety, itching, abdominal pain, jaundice, dry eyes or dry mouth, or fluid buildup around the abdomen, feet, or ankles
Test procedure
A blood sample is drawn from a vein, usually from the inside of the elbow or the back of the hand
No fasting is required
Results
The normal range of AMA is < 9 IU/mL
The presence of these antibodies indicates damage to the thyroid cells or the presence of other autoimmune diseases
Associated conditions Hashimoto’s thyroiditis and Grave’s disease.
Other tests
A doctor may order this test along with other tests to help diagnose thyroid problems or other autoimmune conditions
