• HLA DRB5-1 The first of two reported HLA-DRB5 allele results from HLA typing, describing an inherited immune gene used in transplant matching and some disease-association studies.
• HLA DRB5-2 The second of two reported HLA-DRB5 allele results from HLA typing, describing an inherited immune gene used in transplant matching and some disease-association studies.
• Homocysteine An amino acid byproduct of protein metabolism. Elevated levels are linked to increased cardiovascular risk and can reflect low B vitamin (B12, folate, B6) status.
• Honey Bee (I1) IgE Measures IgE antibodies to honey bee venom to check for allergic sensitization in people who have had a reaction to a bee sting.
• Horse Dander (e3) IgE Measures IgE antibodies to horse dander to check for allergic sensitization that may explain symptoms around horses, stables, or horse-hair products.
• House Dust (Greer) (h1) IgE Measures IgE antibodies to a house dust extract (Greer) to check for allergic sensitization to the mixture of allergens found in household dust.
• House Dust (Hollister-Stier) (h2) IgE Measures IgE antibodies to a house dust extract (Hollister-Stier) to check for allergic sensitization to the mixture of allergens found in household dust.
• Human Chorionic Gonadotropin (hCG), Beta Subunit, QuantitativehCG Measures total hCG, the pregnancy hormone, in your blood — used to confirm pregnancy or, in other contexts, to help detect certain tumors.
• Human Chorionic Gonadotropin (hCG), Qualitative A urine test that checks for human chorionic gonadotropin (hCG), the hormone made during pregnancy, to show whether you are likely pregnant.
• Human Chorionic Gonadotropin (hCG), Total, Qualitative A pregnancy test that simply reports whether hCG, the pregnancy hormone, is present in your blood — a positive or negative result rather than an exact number.
• Human Herpesvirus 7 (HHV-7) Antibody (IgG), Titer Measures IgG antibodies to human herpesvirus 7 as a titer, showing past infection and, when compared over time, possible recent infection.
• Human Herpesvirus 7 (HHV-7) Antibody (IgM), Titer Measures IgM antibodies to human herpesvirus 7 as a titer, which can suggest a recent or reactivated HHV-7 infection.
• Hyaline Casts Clear, cylinder-shaped protein structures formed in the kidney tubules, counted in urine microscopy as one of several clues to kidney function and hydration.
• Hydroxyitraconazole The main active breakdown product of the antifungal medicine itraconazole, measured in serum to help check that drug levels are in an effective range.
• IA-2 Antibody An autoantibody that attacks insulin-producing cells. Used along with other markers to help diagnose type 1 diabetes.
• IFNL3 Genotype A pharmacogenomic test reporting your IFNL3 (IL28B) gene variant, which has been linked to how well hepatitis C responds to interferon-based treatment.
• IFNL3 Phenotype The interpreted result of IFNL3 (IL28B) testing, describing whether your genotype is linked to a more or less favourable response to interferon-based hepatitis C treatment.
• IGF Binding Protein 3IGFBP 3 A protein that binds and regulates IGF-1. Tested alongside IGF-1 to evaluate growth hormone-related conditions.
• Immature Granulocytes The number of young, not-yet-mature white blood cells in circulation — a rise can be an early sign of infection or bone marrow stress.
• Immature Granulocytes (%) The percentage of young, not-yet-mature white blood cells in circulation — a rise can be an early sign of infection or bone marrow stress.
