• Hereditary Hemochromatosis DNA Analysis A genetic test for mutations that cause hereditary hemochromatosis, a condition that leads to excess iron absorption and buildup in the body.
• Hereditary Hemochromatosis (HFE) Gene A genetic test for variants in the HFE gene, which helps control iron absorption, used to check for inherited risk of hereditary hemochromatosis (iron overload).
• Herpes Simplex Virus 1 IgGHSV-1 Indicates past exposure to herpes simplex virus type 1, commonly associated with oral herpes/cold sores.
• Herpes Simplex Virus 1 (IgG), Type-Specific Antibody Measures IgG antibodies specific to herpes simplex virus type 1, showing whether you have been infected with HSV-1 at some point in your life.
• Herpes Simplex Virus 2 IgGHSV-2 Indicates past exposure to herpes simplex virus type 2, commonly associated with genital herpes.
• Herpesvirus 6 Antibodies (IgG)HHV-6 Indicates past exposure to human herpesvirus 6, a common virus best known for causing roseola in young children.
• Herpesvirus 6 Antibodies (IgM) Measures IgM antibodies to human herpesvirus 6, which can suggest a recent or reactivated HHV-6 infection.
• Herring (f205) IgE Measures IgE antibodies to herring to check for allergic sensitization that may explain reactions after eating this fish.
• Heterophile, Mono Screen A rapid screening test for infectious mononucleosis ('mono'), caused by Epstein-Barr virus.
• Hexacosanoic, C26:0 Measures hexacosanoic acid (C26:0), a very long-chain fatty acid, in serum; raised levels can point to inherited peroxisomal disorders.
• Hexacosenoic, C26:1 A very-long-chain monounsaturated fatty acid measured in serum as part of a comprehensive fatty acid profile, mainly to look at how your body handles very long fatty acids.
• Hexadecadienoic, C16:2 A minor 16-carbon polyunsaturated fatty acid measured in serum as part of fatty acid panels that look at nutrition and how your body breaks down fats.
• Hexadecenoic C16:1W9 A 16-carbon omega-9 monounsaturated fatty acid measured in serum as part of fatty acid panels that look at dietary fat intake and fat metabolism.
• H G Linolenic, C20:3W6 Dihomo-gamma-linolenic acid, an omega-6 fatty acid measured in serum fatty acid panels to look at essential fatty acid balance and omega-6 metabolism.
• Hickory/pecan Tree (t22) IgE Measures IgE antibodies to hickory and pecan tree pollen to check for allergic sensitization that may explain spring seasonal allergy symptoms.
• Hickory White (t41) IgE Measures IgE antibodies to white hickory tree pollen, indicating a possible allergic sensitivity to this tree.
• Histamine Measures histamine levels in your blood, a compound released during allergic reactions and by certain rare tumors (mast cell disorders).
• Histone Antibodies Measures antibodies against histones, proteins that package DNA, mainly used to help evaluate drug-induced lupus and other lupus-like autoimmune conditions.
• HLA A*31:01 Genotype A pharmacogenomic test showing whether you carry the HLA-A*31:01 gene variant, which is linked to a higher risk of serious reactions to carbamazepine.
• HLA A*31:01 Phenotype The interpreted result of HLA-A*31:01 testing, stating whether you carry this variant linked to a higher risk of serious reactions to carbamazepine.
