Autoimmunity

The Antinuclear Antibodies (ANA) Pattern test analyzes the specific patterns of antibody staining on cells, providing detailed information that can aid in diagnosing and differentiating various autoimmune diseases. Different patterns, such as homogeneous, speckled, nucleolar, and centromere, are associated with specific autoimmune conditions, helping healthcare providers pinpoint the exact nature of the autoimmune response. This result is only processed if ANA screen is positive.

An ANA test assists in detecting autoimmune disorders. ANAs are autoantibodies produced by the immune system. While healthy antibodies protect the body from pathogens like viruses and bacteria, autoantibodies cause disease by mistakenly attacking healthy cells and tissues. This result is only processed if ANA screen is positive.

The Antinuclear Antibodies (ANA) Screen is a blood test that detects the presence of antibodies that mistakenly target and attack the nucleus of the body’s cells. A positive ANA test suggests an autoimmune response, but further tests are usually required to determine the specific condition and guide appropriate treatment.

Rheumatoid factors (RFs) are antibodies produced by the immune system. The presence of RFs can indicate autoimmune disorders such as rheumatoid arthritis, rheumatoid vasculitis, or Sjögren’s syndrome. Asymptomatic individuals with elevated RF levels may have pre-autoimmunity.
