• Giant Ragweed (Tall) (w3) IgE Measures IgE antibodies to giant ragweed pollen to check for allergic sensitization linked to late-summer and fall hay fever.
• Giardia lamblia Antigen A stool test that detects Giardia antigen, used to look for giardiasis, an intestinal parasite infection that causes diarrhea.
• Ginger (f270) IgE Measures IgE antibodies to ginger to check for allergic sensitization that may explain reactions after eating ginger or foods that contain it.
• Gliadin (Deamidated) Antibody (IgA) Measures IgA antibodies to deamidated gliadin, a gluten fragment, used to help evaluate celiac disease alongside other celiac tests.
• Gliadin (Deamidated) Antibody (IgG) Measures IgG antibodies to deamidated gliadin, a gluten fragment, used to help evaluate celiac disease, especially when IgA is low.
• Glial Fibrillary Acidic ProteinGFAP A protein released by brain support cells (astrocytes) when they're injured. Studied as a marker of brain injury and certain neurological conditions.
• G Linolenic, C18:3W6 Measures gamma-linolenic acid (GLA), an omega-6 fatty acid, in serum to help assess omega-6 metabolism and overall fatty acid balance.
• Globulin A group of blood proteins that includes antibodies and various transport proteins. Assessed together with albumin to evaluate liver, kidney, and immune function.
• Glucagon Measures glucagon, a pancreatic hormone that raises blood sugar, used to investigate unusual blood sugar control or rare glucagon-producing tumors.
• Glucose Your blood sugar level at the time of the test — a core marker for diagnosing and monitoring diabetes and metabolic health.
• Glucose, 1-Hour (after 50 g Oral Glucose) Your blood glucose one hour after a 50 g glucose drink, used as a screening test for gestational diabetes during pregnancy.
• Glucose, 1-Hour (after 75 g Oral Glucose) Your blood glucose one hour after a 75 g glucose drink, part of an oral glucose tolerance test used to assess how your body handles sugar.
• Glucose, 1-Hour (Post-Challenge) Your blood glucose one hour after the 100 g glucose drink in a four-sample pregnancy glucose tolerance test for gestational diabetes.
• Glucose, 2-Hour (after 75 g Oral Glucose) Your blood glucose two hours after a 75 g glucose drink, a key value in the oral glucose tolerance test for diabetes and prediabetes.
• Glucose, 2-Hour (Post-Challenge) Your blood glucose two hours after the 100 g glucose drink in a four-sample pregnancy glucose tolerance test for gestational diabetes.
• Glucose, 2nd Specimen Your blood glucose in the second sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
• Glucose, 30-Minute (after 75 g Oral Glucose) Your blood glucose 30 minutes after a 75 g glucose drink, part of an extended glucose tolerance test that tracks your early sugar response.
• Glucose, 3-Hour Your blood glucose three hours after the 100 g glucose drink, the final sample of a pregnancy glucose tolerance test for gestational diabetes.
• Glucose, 3-Hour (after 75 g Oral Glucose) Your blood glucose three hours after a 75 g glucose drink, part of an extended glucose tolerance test that also looks for late drops in sugar.
• Glucose, 3rd Specimen Your blood glucose in the third sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
