Laboratory

rheumatologic-disease-commercial-laboratory-medical-care

CAA has an on-site laboratory capable of processing routine studies for general medical care. We also offer specialized autoantibody testing needed to follow patients with rheumatologic diseases.

If only a portion of the lab results are performed in our office, we will draw the blood tests in our office and send them to the appropriate commercial laboratory.

When paired with physical examinations, blood tests are an effective way to confirm and diagnose potential disease activity. Our on-site laboratory helps determine results, which are classified as positive or negative. If a rheumatic disease is diagnosed due to positive test results, further laboratory testing can show our physicians the extent of the disease and guide their treatment process.

Antinuclear Antibody Testing

Antibodies are proteins that develop in the body’s immune system to combat infectious germs. Sometimes antibodies make the mistake of identifying normal proteins in the body as “foreign,” which causes the body to attack itself. These antibodies are identified as autoantibodies, and they incorrectly work to target “normal” proteins within the nucleus of a cell. They’re also known as antinuclear antibodies, and most people have them in small amounts within the body. When there’s a large presence found, it can indicate existing autoimmune diseases, including Sjogren’s Syndrome, lupus, scleroderma, connective tissue diseases, and cases of juvenile arthritis.

Sometimes patients get a “false positive” ANA test result, which means an autoimmune disease does not actually exist in the body. Certain medications trigger false positive results, so it’s important to let your doctor know about any prescriptions you’re currently taking.

Testing Positive for an Autoimmune Disease

If you find out you’ve tested positive for an autoimmune disease, our doctors will work with you to determine the next steps. There are many available treatments to consider, so please talk to our physicians about any and all of your concerns.
