• Dihydrotestosterone (DHT), Free The portion of DHT that's unbound and biologically active in your tissues, rather than bound to carrier proteins.
• Dill (f277) IgE Measures IgE antibodies to dill, a herb and spice, to check for allergic sensitization that may relate to reactions after eating foods seasoned with it.
• Dilute Russell's Viper Venom Time (DRVVT) Screen A clotting test that helps screen for lupus anticoagulant, an antibody linked with a higher risk of blood clots and some pregnancy complications.
• Diphtheria Antitoxoid Measures antibodies against diphtheria toxin to check your immunity from vaccination, and sometimes how well your immune system responds to vaccines.
• Direct Bilirubin The form of bilirubin already processed by your liver. Elevated levels point toward a liver or bile-duct problem rather than red blood cell breakdown.
• Direct LDL Measures LDL cholesterol directly rather than calculating it, useful when triglycerides are high or you are not fasting, to help assess cardiovascular risk.
• DNase-B Antibody An antibody that shows evidence of a recent strep infection. Used to help diagnose post-strep conditions like rheumatic fever or kidney inflammation (glomerulonephritis).

• Docosahexaenoic Acid (DHA), C22:6 Omega-3 Measures DHA (C22:6 omega-3), a long-chain omega-3 fatty acid from fish and seafood, in serum as part of a fatty acid panel.
• Docosanoic Acid, C22:0 Measures docosanoic (behenic) acid, C22:0, a very long-chain saturated fatty acid, as part of a serum fatty acid panel.
• Docosapentaenoic AcidDPA Measures DPA, a long-chain omega-3 fatty acid between EPA and DHA, as a percentage of total fatty acids in whole blood.
• Docosapentaenoic Acid (DPA), C22:5 Omega-3 Measures omega-3 DPA (C22:5 omega-3), a long-chain fatty acid between EPA and DHA, in serum as part of a fatty acid panel.
• Docosapentaenoic Acid (DPA), C22:5 Omega-6 Measures omega-6 DPA (C22:5 omega-6), a long-chain omega-6 fatty acid, in serum as part of a fatty acid panel looking at fat balance.
• Docosatetraenoic Acid (DTA), C22:4 Omega-6 Measures DTA (adrenic acid, C22:4 omega-6), a long-chain omega-6 fatty acid made from arachidonic acid, in serum as part of a fatty acid panel.
• Docosenoic, C22:1 Measures docosenoic acid (C22:1), a very long-chain monounsaturated fatty acid such as erucic acid, as part of a serum fatty acid panel.
• Dog Dander (e5) IgE Measures IgE antibodies to dog dander to check for allergic sensitization that may explain sneezing, itchy eyes or asthma around dogs.
• Dog Fennel (w46) IgE Measures IgE antibodies to dog fennel pollen, a weed common in the southeastern US, to check for allergic sensitization linked to late-summer and autumn symptoms.
• Dog Serum Albumin (re221) IgE Measures IgE antibodies to dog serum albumin (Can f 3), a dog protein shared with other mammals, to help understand dog allergy and cross-reactivity.
• Dopamine Measures dopamine in plasma, part of a catecholamine panel that helps look for rare tumors producing these hormones; it does not reflect brain dopamine.
• Double-Stranded DNA (dsDNA) Antibodyanti-dsDNA Antibodies against double-stranded DNA. Highly specific for lupus and often used to track disease activity.
