The Methylmalonic Acid (MMA) Blood Test measures MMA levels in the bloodstream to help detect vitamin B12 deficiency, often before anemia or neurological symptoms appear. Elevated results may indicate poor B12 absorption, pernicious anemia, or metabolic disorders. Doctors order this test when patients present with fatigue, neuropathy, or unexplained anemia. Results provide early insight into nutritional status, metabolic health, and treatment needs.

The Myelin Associated Glycoprotein (MAG) SGPG IgM Antibody Test detects antibodies against MAG and sulfated glucuronyl paragloboside (SGPG), markers linked to demyelinating neuropathies. Elevated IgM antibodies may indicate autoimmune neurological disorders, including peripheral neuropathy or chronic inflammatory demyelinating polyneuropathy. This test supports diagnosis, monitoring, and evaluation of immune-mediated nerve damage.

The Protein Total Serum Test evaluates total protein concentration, reflecting both albumin and globulin, which play key roles in immune response, liver function, and nutrient transport. Abnormal findings may signal malnutrition, kidney or liver disease, or chronic inflammatory conditions. This test aids in assessing protein metabolism, systemic health, and overall physiological balance.

The Rheumatoid Factor (RF) Test measures RF antibodies in blood to help diagnose rheumatoid arthritis and other autoimmune conditions. High RF levels may indicate rheumatoid arthritis, Sjögren’s syndrome, or other connective tissue diseases, though they can also appear in some infections. Doctors order this test to investigate joint pain, stiffness, or swelling. Results provide important insight into autoimmune activity, joint health, and inflammatory disease management.

The Rheumatoid Factor IgA Antibody Test measures IgA-class rheumatoid factor, an autoantibody linked to rheumatoid arthritis and other autoimmune diseases.
