Autoimmune Panel

Antinuclear Antibodies (ANA) is a blood test marker that measures autoantibodies directed against material in the cell nucleus. On a lab report, ANA is often used as a broad screening value within an autoimmune panel, helping show patterns in immune activity rather than one single condition. The ANA test result is usually reported as a titer and pattern, which makes the ANA normal range different from many routine blood values.

Rheumatoid Factor (RF) is a measured blood marker that reflects the amount of rheumatoid factor present in a sample. On a Rheumatoid Factor on a blood test or lab report, the RF result helps describe whether the level is within the normal range, above it, or below it. The value is often reviewed with other immune-related markers to build a broader picture of blood test results.

Anti-Cyclic Citrullinated Peptide (Anti-CCP) is a blood test marker that measures antibodies directed against citrullinated peptides. On an Anti-CCP lab report, the value helps describe immune activity in relation to certain joint-related conditions. The Anti-CCP test is usually reported in units per milliliter and is often read with other autoimmune markers.

Complement C3 (C3) is a complement system protein measured in blood. It is often reviewed as part of immune-related testing, where the Complement C3 test can help describe how much of this protein is present in circulation. On a lab report, C3 results are read alongside other markers to understand the broader blood profile.

Complement C4 (C4) is a blood protein in the complement system, which is part of the immune-related protein network in plasma. On a lab report, C4 is read as a concentration value that helps describe how much of this protein is present at the time of testing. The Complement C4 test is often used with other markers to show a broader pattern in blood results.

Anti-Double Stranded DNA (Anti-dsDNA) is a blood test marker that measures antibodies that bind to double-stranded DNA. It is usually reported as part of an autoimmune panel rather than a routine chemistry panel. Anti-dsDNA on a lab report helps describe immune activity, and the Anti-Double Stranded DNA normal range depends on the lab method used.

Anti-Smith Antibody (Anti-Sm) is a blood test marker that measures antibodies directed against Smith antigens in the body. Anti-Sm on a lab report is used as part of an autoimmune panel and helps show whether this immune marker is present and at what level. The Anti-Sm result is usually reported as positive, negative, or by index rather than a standard numeric concentration.
