The analysis of 17-hydroxyprogesterone (17-OHP) is 1 of the 3 analytes along with Cortisol and Androstenedione that constitutes the best screening test for Congenital Adrenal Hyperplasia (CAH), caused by either 11- or 21-hydroxylase deficiency. Analysis for 17-OHP is also useful as part of a battery of tests to evaluate females with hirsutism or infertility; both can result from adult-onset CAH.
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.
.
ANAs are a special class of autoantibodies that bind and destroy certain parts in the nucleus of the cell. Although a little amount of ANA is found in the normal population, an increased level is normally observed in people with connective tissue disease (CTD).

Antinuclear antibodies (ANA) are autoantibodies that bind to components within the cell nucleus, and a positive ANA test can indicate an autoimmune condition, though it’s not specific for any particular disease.
ANAs are a type of autoantibody, meaning they are antibodies that your immune system mistakenly produces against your own body’s tissues.
Specifically, ANAs target the cell nucleus, which contains DNA and other important components.
A positive ANA test can be a sign of an autoimmune disease, where the immune system attacks healthy cells and tissues.
ANAs are often associated with autoimmune diseases like systemic lupus erythematosus (SLE), Sjögren’s syndrome, and systemic sclerosis (SSc), among others.
The ANA test is a blood test that looks for the presence and amount of antinuclear antibodies in your blood.
A positive ANA test means that the test detected a higher-than-normal level of antinuclear antibodies in your blood.
A positive ANA test may indicate a need for follow up blood tests, physical exam, and a review of history and symptoms.
No, not always. Many healthy individuals can have detectable levels of ANAs, and the presence of ANAs alone doesn’t necessarily mean you have an autoimmune disease.
The ANA test is used as a screening tool for autoimmune diseases, but it’s important to note that a positive ANA test doesn’t confirm a specific diagnosis.
If you have a positive ANA test, your doctor may order further tests to help determine the cause of the elevated ANA levels and to rule out or confirm specific autoimmune diseases.
