• ALDO/PRA Ratio A ratio calculated from aldosterone and plasma renin activity, used mainly to screen for primary aldosteronism as a cause of high blood pressure.
• Aldosterone, LC/MS/MS Measures aldosterone, the adrenal hormone that controls salt, potassium and blood pressure, using a precise mass spectrometry method.
• Alfalfa IgE Measures IgE antibodies to alfalfa, a legume plant, used to check for allergic sensitization that may explain your symptoms.
• A-Linolenic C18:3W3 Measures alpha-linolenic acid in serum, the plant-based omega-3 fatty acid that comes from foods like flaxseed, walnuts and canola oil.
• Alkaline PhosphataseALP An enzyme found mainly in the liver and bones. High levels can signal liver disease, bile duct blockage, or bone conditions.
• Allergen Specific IgE Hackberry Measures IgE antibodies to hackberry tree pollen, used to check for allergic sensitization that may explain your symptoms.
• Almond (f20) IgE Measures IgE antibodies to almond, a tree nut, used to check for allergic sensitization that may explain your symptoms.
• Almond (f20) IgG4 Measures IgG4 antibodies to almond, which mainly reflect that you have eaten it; their link to food-related symptoms is debated.
• Alpha-1-Antitrypsin, Quantitative Measures the level of alpha-1 antitrypsin, a protein made by the liver that protects the lungs, used to look for inherited deficiency.
• Alpha-1 Globulin One of the protein groups measured in a protein electrophoresis test. Changes in this fraction can be an early sign of inflammation or certain liver or lung conditions.
• Alpha-2 Globulin One of the protein groups measured in a protein electrophoresis test. Elevated levels are often seen with inflammation, kidney disease (nephrotic syndrome), or certain cancers.
• Alpha Fetoprotein, Tumor MarkerAFP Alpha-fetoprotein, a protein used to help detect and monitor liver cancer and certain germ cell tumors, and during pregnancy to screen for fetal conditions.
• Alternaria alternata (m6) IgE Measures IgE antibodies to the mould Alternaria alternata, used to check for allergic sensitization that may explain your symptoms.
• Aluminum Measures aluminum in your blood, used mainly to check for buildup in people with reduced kidney function or with occupational or medical exposure.
• American Cockroach (i206) IgE Measures IgE antibodies to the American cockroach, used to check for allergic sensitization that may explain your symptoms.

• Amoxicillin (c6) IgE Measures IgE antibodies to amoxicillin, a penicillin-type antibiotic, used to check for allergic sensitization that may explain your symptoms.
• Amylase An enzyme that helps digest carbohydrates, produced mainly by the pancreas and salivary glands. Elevated levels can signal pancreatitis or salivary gland problems.
• Amyloid Beta 40 Peptide Measures amyloid beta 40 in plasma, a common protein fragment from the brain used together with amyloid beta 42 to calculate the 42/40 ratio.
• Amyloid Beta 42/40 Ratio A ratio calculated from amyloid beta 42 and amyloid beta 40 in plasma, used to help estimate the likelihood of amyloid plaques in the brain.
