• Crab (f23) IgE Measures IgE antibodies to crab, a shellfish, to check for allergic sensitization that may explain reactions after eating crab or other crustaceans.
• Crab (f23) IgG4 Measures IgG4 antibodies to crab, which reflect exposure to this shellfish; how food IgG4 relates to symptoms is debated.
• Cranberry (rf341) IgE Measures IgE antibodies to cranberry to check for allergic sensitization that may relate to reactions after eating cranberries, juice or cranberry-containing foods.
• Crayfish (rf320) IgE Measures IgE antibodies to crayfish, a freshwater crustacean, to check for allergic sensitization that may explain reactions after eating crayfish or similar shellfish.
• C-Reactive Protein, High Sensitivityhs-CRP A sensitive marker of low-grade inflammation in the body, commonly used to help assess cardiovascular disease risk.
• C-Reactive Protein, InflammationCRP A general marker of inflammation in the body, elevated with infections, injuries, and many inflammatory or autoimmune conditions.
• Creatine KinaseCK An enzyme found in muscle, heart, and brain tissue. Elevated levels typically indicate muscle damage, from injury, intense exercise, or certain medical conditions.
• Creatine Kinase BBCK-BB A form (isoenzyme) of creatine kinase found mainly in brain tissue. Less commonly used clinically than the heart- and muscle-specific forms.
• Creatine Kinase MBCK-MB A form of creatine kinase found mainly in heart muscle. Historically used to help detect heart muscle damage, such as a heart attack.
• Creatine Kinase MMCK-MM A form of creatine kinase found mainly in skeletal muscle. Elevated levels typically reflect muscle injury or strenuous exercise rather than heart damage.
• Creatinine A waste product from muscle metabolism, filtered by your kidneys. One of the main markers used to assess kidney function.
• Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
• Creatinine, Random Measures creatinine in a random urine sample, mainly used as a reference to adjust other urine results for how concentrated or dilute the sample is.
• Creatinine, Urine Random Measures creatinine in a random urine sample, used here as a reference to adjust the methylmalonic acid result for how dilute the urine is.
• Cryptosporidium Antigen Looks for Cryptosporidium antigen in a stool sample, used to help find this waterborne parasite as a cause of watery diarrhea.
• Crystals Looks for crystals in your urine under the microscope, which are often harmless but can sometimes relate to kidney stones, metabolism or medications.
• C-TelopeptideCTx Measures C-telopeptide (CTx), a fragment released when bone is broken down, used to help look at bone turnover and monitor osteoporosis treatment.
• Cucumber (f244) IgE Measures IgE antibodies to cucumber to check for allergic sensitization that may explain mouth itching or other reactions after eating raw cucumber.
• Cucumber (f244) IgG4 Measures IgG4 antibodies to cucumber, which reflect exposure to this food; how food IgG4 relates to symptoms is debated.
• Cultivated Oat (g14) IgE Measures IgE antibodies to cultivated oat pollen to check for allergic sensitization that may relate to seasonal hay fever symptoms, particularly in farming areas.
