• Cystatin C An alternative marker of kidney function that, unlike creatinine, isn't affected by muscle mass — useful for a more precise eGFR estimate.
• Cytomegalovirus IgG AntibodyCMV Indicates past exposure or infection with cytomegalovirus (CMV), a common virus that's usually harmless but can be a concern during pregnancy or with a weakened immune system.
• Cytomegalovirus IgM AntibodyCMV Indicates a recent or active CMV infection, as opposed to past exposure.
• Dandelion (w8) IgE Measures IgE antibodies to dandelion pollen, a common weed, to check for allergic sensitization that may relate to spring and summer allergy symptoms.
• Date (f289) IgE Measures IgE antibodies to date fruit to check for allergic sensitization that may explain reactions after eating dates or foods made with them.
• D-Dimer, Quantitative A protein fragment released when a blood clot breaks down. Used mainly to help rule out blood clots like DVT or pulmonary embolism.
• Deamidated Gliadin Peptide IgADGP An antibody used to help screen for celiac disease, particularly useful in young children or when tissue transglutaminase results are unclear.
• Deamidated Gliadin Peptide IgGDGP An antibody used to help screen for celiac disease, especially useful in people with IgA deficiency.
• Decanoic, C10:0 Measures decanoic acid (C10:0), a medium-chain saturated fatty acid, as part of a serum fatty acid panel that can help look at fat metabolism.
• Decenoic, C10:1 Measures decenoic acid (C10:1), a medium-chain unsaturated fatty acid, as part of a serum fatty acid panel that can help look at fat metabolism.
• DehydroepiandrosteroneDHEA A hormone produced by the adrenal glands that serves as a building block for testosterone and estrogen. Reflects adrenal androgen production.
• Dehydroepiandrosterone SulfateDHEA-S The sulfated, more stable form of DHEA. A reliable marker of adrenal androgen production, used to evaluate adrenal function and androgen excess.
• Deoxycholic Acid A secondary bile acid formed by gut bacteria breaking down primary bile acids. Measured as part of detailed bile acid panels.
• Deoxycorticosterone Measures deoxycorticosterone (DOC), a mineralocorticoid made on the way to aldosterone, to help evaluate adrenal enzyme problems and some causes of high blood pressure.
• Deoxypyridinoline, Urine, Ratio to CRT Measures deoxypyridinoline, a bone collagen breakdown product, in urine relative to creatinine, to help look at the rate of bone resorption.
• Dermatophagoides farinae (d2) IgE Measures IgE antibodies to the American house dust mite (D. farinae) to check for allergic sensitization that often causes year-round indoor allergy symptoms.
• Dermatophagoides pteronyssinus (d1) IgE Measures IgE antibodies to the European house dust mite (D. pteronyssinus) to check for allergic sensitization that often causes year-round indoor allergy symptoms.
• Dexamethasone Measures blood levels of the steroid medication dexamethasone, often checked alongside cortisol testing (dexamethasone suppression test) to evaluate adrenal function.
• DHT, Percent Free Dialysis Reports the percentage of dihydrotestosterone (DHT) circulating unbound to proteins, measured by equilibrium dialysis, and used to calculate free DHT.
• DihydrotestosteroneDHT A potent form of testosterone converted by an enzyme in skin, hair follicles, and the prostate. Linked to hair loss, acne, and prostate growth.
