Laboratory tests in rheumatology in Barranquilla, Colombia

Which lab tests are used in rheumatology?

The most common are rheumatoid factor and anti-CCP antibodies (rheumatoid arthritis), antinuclear antibodies (ANA) and anti-DNA (lupus and other autoimmune diseases), ESR and CRP (inflammation), uric acid (gout), HLA-B27 (spondyloarthritis) and complement.

When are they ordered?

For joint pain and swelling lasting weeks, prolonged morning stiffness, unexplained fatigue with fever, skin rashes triggered by sun, very dry eyes or mouth, or persistent low back pain in young people.

Does a positive result mean I have the disease?

Not necessarily. Some antibodies, such as ANA, can be positive in healthy people, especially with age, and others can be negative even when the disease is present. That is why diagnosis always combines tests with symptoms and a physical exam.

Who interprets them?

A rheumatologist is the right specialist. A general practitioner or internist can order initial tests and refer you if findings are suggestive.
