• Cacao (Chocolate) (f93) IgG Measures IgG antibodies to cacao, the source of chocolate, as part of a food panel; food IgG reflects exposure, and its link to symptoms is debated.
• Cadmium Measures cadmium, a toxic metal, in your blood to check for recent or ongoing exposure, such as from smoking or certain workplaces.
• Calcitonin A hormone produced by the thyroid's C-cells that helps regulate calcium. Used mainly to screen for and monitor medullary thyroid cancer.
• Calcitriol (1,25 di-OH Vitamin D) The active, hormone form of vitamin D that directly regulates calcium absorption. Tested less often than 25-OH vitamin D, mainly for kidney or calcium-regulation disorders.
• Calcium Measures the total calcium in your blood, important for bone health, muscle function, nerve signaling, and blood clotting.
• Calcium (Adjusted For Albumin) A calculated calcium value that corrects your total calcium for your albumin level, giving a better estimate of calcium status when albumin is abnormal.
• Calcium, Ionized Measures the active, unbound form of calcium in your blood — considered a more precise reflection of calcium available to your body's cells than total calcium.
• Calcium Oxalate Crystals Reports calcium oxalate crystals seen when a urine sample is examined under the microscope, which can be normal or linked to kidney stone risk.
• Calprotectin Measures calprotectin in stool, a marker of inflammation in the intestines, used to help tell inflammatory bowel disease from non-inflammatory conditions.
• Canary Bird Feathers (e201) IgE Measures IgE antibodies to canary feathers to check for allergic sensitization in people exposed to pet birds or feather dust.
• Canary Grass (g71) IgE Measures IgE antibodies to canary grass pollen to check for allergic sensitization linked to seasonal hay fever symptoms.
• Cancer Antigen 125CA 125 A protein used mainly to monitor ovarian cancer treatment and detect recurrence; it can also be elevated by non-cancerous conditions like endometriosis.
• Cancer Antigen 15-3CA 15-3 A tumor marker used mainly to monitor breast cancer treatment and check for recurrence.
• Cancer Antigen 19-9CA 19-9 A tumor marker used mainly to monitor pancreatic cancer, and sometimes other gastrointestinal cancers, rather than to screen for them.
• Cancer Antigen 27-29CA 27-29 A tumor marker used to help monitor breast cancer treatment response and watch for recurrence.
• Candida albicans IgA Measures IgA antibodies to Candida albicans, a common yeast, to look at the immune response to this organism in suspected Candida infection.
• Candida albicans IgG Measures IgG antibodies to Candida albicans, a common yeast, to look at the immune response to this organism in suspected Candida infection.
• Candida albicans IgG4 Measures IgG4 antibodies to Candida albicans yeast as part of a food panel; IgG4 mainly reflects exposure, and its link to symptoms is debated.
• Candida albicans IgM Measures IgM antibodies to Candida albicans, a common yeast, to look at the immune response to this organism in suspected Candida infection.
• Candida albicans Immune Complex Measures circulating immune complexes containing Candida albicans, which form when antibodies bind to the yeast, to look at the immune response to Candida.
