What are anti-nuclear antibodies (ANA)?
Anti-nuclear antibodies (ANA) are proteins in the blood that can attack the nuclei of cells, leading to inflammation and damage. The Anti-nuclear Antibodies Test is used to detect the presence of these antibodies, which can indicate an autoimmune disease.
Conditions associated with positive ANA test results
A positive ANA test can be associated with various autoimmune diseases, including:
- Sjögren’s syndrome
- Juvenile arthritis
- Polymyositis and dermatomyositis
Test procedure and interpretation
The ANA test is a blood test that looks for certain patterns and intensity of antibodies under a microscope. A doctor will interpret the results based on the patient’s clinical history. While a positive ANA test indicates the presence of anti-nuclear antibodies, it does not confirm a diagnosis of an autoimmune disease.
Accuracy and limitations
Our Anti-nuclear Antibodies Test is a reliable and accurate diagnostic tool for assessing potential autoimmune diseases. However, only about 11-13% of people with a positive ANA test have an autoimmune disease, and up to 15% of healthy individuals have a positive ANA test. Therefore, the test does not confirm a diagnosis of an autoimmune or connective tissue disease. Choose our Anti-nuclear Antibodies Test for a comprehensive analysis of your autoimmune health and early detection of potential autoimmune diseases.
