Description
The antinuclear antibody (ANA) panel helps diagnose autoimmune conditions like lupus or rheumatoid arthritis; patients in China may need it for unexplained rashes, joint pain, or fatigue, with costs typically ranging ¥500–¥1,000 and ChinaMedicalHub assisting with hospital booking and interpreter support.
Main Uses
The primary purpose of the ANA panel is to help diagnose autoimmune diseases, particularly systemic lupus erythematosus (SLE). It is also used to monitor the progression of these conditions and to evaluate the effectiveness of treatment. The test is applicable in scenarios where patients present with symptoms suggestive of an autoimmune disorder, such as joint pain, fatigue, and skin rashes.
Normal Range
The normal range for an Antinuclear Antibody (ANA) panel is typically negative or a titer of less than 1:40. Specific patterns and their titers may vary, but generally, a titer below 1:80 is considered within the normal range for most laboratories.
Low Values - Possible Causes
Low values in an ANA test are usually not clinically significant as the test is designed to detect the presence of autoantibodies. However, a negative or low result can indicate: absence of autoimmune disease, early stage of an autoimmune condition, or that the patient's immune response is too weak to produce detectable levels of antibodies.
High Values - Possible Causes
High values in an ANA test can be caused by: Systemic Lupus Erythematosus (SLE), Sjögren's syndrome, Rheumatoid Arthritis, Mixed Connective Tissue Disease, and other autoimmune disorders. Additionally, some infections, certain medications, and even healthy individuals (especially elderly) can have elevated ANA levels without having an autoimmune disease.
