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.
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.
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.
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.
The test detects antibodies against antigens like dsDNA, nucleosomes, histones, rib, SS-A, Ro-52, Scl-70, and PM-Scl.
A positive result indicates the presence of ANAs, suggesting a possible autoimmune disease.
To help differentiate between different autoimmune conditions based on the specific antibodies detected.
A positive ANA test result doesn’t necessarily mean you have an autoimmune disease, as many healthy individuals also have ANAs in their blood.

An arthritis profile is a series of blood tests used to help diagnose and assess arthritis, focusing on inflammatory markers and autoimmune activity. It can help determine the type and severity of arthritis and guide treatment plans.
The arthritis profile helps doctors understand the underlying causes of arthritis, differentiate between different types (like rheumatoid arthritis and osteoarthritis), and monitor the effectiveness of treatment.
Common tests in an arthritis profile include:
The arthritis profile is typically a blood test, but may also include a urine sample.
Elevated levels of inflammatory markers (CRP, ESR) or the presence of certain autoantibodies (RF, anti-CCP) can suggest arthritis or other autoimmune conditions.
Arthritic disorders affect majority of the population, varying in severity. Many of these disorders are self limiting conditions requiring minimal evaluation and symptomatic therapy. However several patients show persistent musculo-skeletal symptoms that requires laboratory testing to establish diagnosis and document the pathological process. Complement mediated immune complex deposition may also result in arthritic changes.
