The SS-B/La measures the presence of antibodies against the SS-B antigen in the blood. These antibodies are often associated with autoimmune disorders, particularly Sjorgen's syndrome. This test is used alongside SS-A (Ro) antibody test to help in the diagnosis of Sjogren's syndrome and other autoimmune diseases like Systemic lupus erythematosus (SLE). Detecting SS-B antibodies helps doctors assess autoimmune activity, confirm diagnosis and differentiate between various autoimmune conditions. However, the presence of SS-B antibodies alone is not definitive, and results should be interpreted in conjunction with clinical symptoms and other laboratory findings.

The ds-DNA test detects the presence of antibodies specifically directed against the genetic material called double-stranded DNA (dsDNA) found in the nucleus of cells. These antibodies are often found in systemic lupus erythematosus (SLE), an autoimmune disease where the immune system mistakenly attacks its own DNA. A positive result means that these antibodies are present, suggesting active disease or flare-ups, especially in the kidneys. A negative result means the antibodies were not found, making SLE less likely but not ruling it out completely. This test helps doctors understand if the disease is active and monitor how well treatments are working.

An Anti-Nuclear Antibody (ANA) by IFA - End Point Titer test checks for antinuclear antibodies (ANA) in your blood. These antibodies, different from typical ones that fight off invaders in the body, can attach to structures inside the body’s own cell nuclei. If ANAs are present in the blood, it may suggest that your immune system is overly sensitive, causing inflammation against your own tissues and possibly indicating autoimmune diseases.
