• Lupine Seed (f335) IgE Measures IgE antibodies to lupine (lupin) seed to check for allergic sensitization that may explain reactions to foods containing lupin flour.
• Lupus Anticoagulant Detects lupus anticoagulant, an antiphospholipid antibody that prolongs clotting tests in the lab but is linked to an increased risk of blood clots.
• Luteinizing HormoneLH A pituitary hormone that triggers ovulation in women and stimulates testosterone production in men. Used to evaluate fertility, menstrual irregularities, and reproductive hormone disorders.
• Lyme Disease Antibodies (IgG), Immunoblot The overall interpretation of an IgG Western blot (immunoblot) for Lyme disease, based on the pattern of antibody bands against Borrelia proteins.
• Lyme Disease Antibodies (IgM), Immunoblot The overall interpretation of an IgM Western blot (immunoblot) for Lyme disease, based on the pattern of antibody bands against Borrelia proteins, used mainly in early infection.
• Lyme IgG Line Blot Interp. The overall interpretation of a Lyme disease IgG line blot, based on the pattern of antibody reactions to Borrelia proteins under CDC criteria.
• Lyme IgM Line Blot Interp. The overall interpretation of a Lyme disease IgM line blot, based on the pattern of antibody reactions to Borrelia proteins, used mainly in early infection.
• Lymphocytes The number of lymphocytes, white blood cells central to your immune response (including T-cells, B-cells, and NK cells), in your blood.
• Lymphocytes (%) The percentage of your white blood cells that are lymphocytes, key immune cells including T-cells, B-cells, and NK cells.
• Lysozyme (rk208) IgE Measures IgE antibodies to lysozyme, an egg-white protein also used as a food and medicine additive, to check for allergic sensitization.
• Macadamia Nut (rf345) IgE Measures IgE antibodies to macadamia nut to check for allergic sensitization that may explain reactions after eating macadamia nuts.
• Mackerel (f206) IgE Measures IgE antibodies to mackerel to check for allergic sensitization that may explain reactions after eating mackerel or other fish.
• Macro CK Type 1 A less common, larger form of creatine kinase bound to an antibody. Usually a benign finding rather than a sign of tissue damage, but can cause a persistently elevated CK result.
• Macro CK Type 2 A less common, larger form of creatine kinase, typically seen in people who are critically ill; unlike Type 1, it can reflect a more serious underlying condition.
• Macrohepatic Isoenzymes A high-molecular-weight form of liver alkaline phosphatase, measured in serum and usually linked to slowed or blocked bile flow.
• Macroprolactin/Prolactin The percentage of your prolactin that's in a large, less biologically active form. Helps determine whether an elevated prolactin result is clinically significant.
• Magnesium Measures magnesium, a mineral essential for muscle, nerve, heart, and bone function.
• Magnesium RBC Measures magnesium stored inside red blood cells, considered a more accurate reflection of your body's magnesium status than a standard serum test.
• Maize/Corn (f8) IgE Measures IgE antibodies to corn (maize) to check for allergic sensitization to this food, helping explain reactions that happen after eating it.
• Maize/Corn (f8) IgG Measures IgG antibodies to corn (maize), which mainly reflect that you have eaten this food; their link to food-related symptoms is debated.
