• Beta-1 Globulin One of the protein groups measured in a protein electrophoresis test, which includes transferrin. Changes can relate to iron status or certain liver and kidney conditions.
• Beta 2 Globulin Measures the beta-2 globulin fraction on serum protein electrophoresis, a group of blood proteins that includes the immune protein complement C3.
• Beta-2-Glycoprotein I Antibody (IgA) Measures IgA antibodies against beta-2-glycoprotein I, one of the antiphospholipid antibodies, used to evaluate antiphospholipid syndrome and causes of blood clots.
• Beta-2-Glycoprotein I Antibody (IgG) Measures IgG antibodies against beta-2-glycoprotein I, one of the antiphospholipid antibodies, used to evaluate antiphospholipid syndrome and causes of blood clots.
• Beta-2-Glycoprotein I Antibody (IgM) Measures IgM antibodies against beta-2-glycoprotein I, one of the antiphospholipid antibodies, used to evaluate antiphospholipid syndrome and causes of blood clots.
• Beta 2 Microglobulin Measures beta-2 microglobulin in serum, a small protein shed by cells, used to look at kidney function and to assess certain blood cancers.
• Bile Acids, Total Measures the total bile acids in your blood, which the liver uses to help digest fat. Elevated levels can indicate liver dysfunction or impaired bile flow.
• Bilirubin Checks for bilirubin in your urine, which is normally absent and can appear when the liver or bile ducts are not working properly.
• Bioavailable Testosterone The portion of your testosterone that's either free or loosely bound to albumin — the amount actually usable by your body's tissues.
• Biotin (Vitamin B7) Measures biotin (vitamin B7) in your blood, a B vitamin needed for energy metabolism and healthy skin, hair and nails, used to assess deficiency or high intake.
• Birch (t3) IgE Measures IgE antibodies to birch tree pollen, used to check for allergic sensitization that may explain your symptoms.
• Blackberry (f211) IgE Measures IgE antibodies to blackberry, used to check for allergic sensitization that may explain your symptoms.
• Black Olive (rf342) IgE Measures IgE antibodies to black olive, from the olive tree, used to check for allergic sensitization that may explain your symptoms.
• Black Pepper (f280) IgE Measures IgE antibodies to black pepper to check for allergic sensitization to this common spice, helping explain reactions after eating seasoned foods.
• Black Pepper (f280) IgG4 Measures IgG4 antibodies to black pepper as part of a food panel; food IgG4 mainly reflects exposure, and its link to symptoms is debated.
• Blasts Counts the number of blasts, very immature blood cells, in your blood sample as part of a full differential blood count.
• Blasts (%) Shows blasts, very immature blood cells, as a percentage of your white blood cells, reported as part of a full differential blood count.
• Blomia tropicalis (d201) IgE Measures IgE antibodies to Blomia tropicalis, a dust mite common in warm, humid climates, to check for allergic sensitization linked to indoor allergy symptoms.
• Blood Group Antibody Screen Checks your blood plasma for antibodies against red blood cell antigens — commonly used before transfusions and during pregnancy to screen for Rh incompatibility.
• Blood Urea NitrogenBUN Blood urea nitrogen, a waste product filtered by your kidneys. Used along with creatinine to assess kidney function and hydration status.
