Coriander/Cilantro (f317) IgE
Labcorp
Not offered
This test measures your body's allergic reaction to coriander/cilantro by checking for specific antibodies called IgE. This test is done in a lab and helps providers figure out if you have a food allergy. It's especially useful when other tests might not be suitable, like if you have skin conditions, have taken certain medicines recently, can't do skin tests, or if there's a high risk of a severe allergic reaction.
Corn,Grass(g202) IgE
Labcorp
Not offered
This test measures the IgE antibody levels in the blood to identify allergic reactions to corn and grass. It's crucial for diagnosing and managing allergies effectively.
Corn Smut, Tilletia tritici (m201), IgE
Labcorp
Not offered
This test measures the IgE antibody response to corn smut, helping to identify allergic reactions to this specific allergen. It's a quantitative assay, meaning it provides precise measurement of IgE levels, and is used alongside other clinical information to assist in diagnosing allergic conditions.
Cortisol
Cortisol is a hormone that helps regulate the body's response to stress. This test can help diagnose conditions such as adrenocortical insufficiency, Addison's disease, adrenocortical hypersecretion, and Cushing's syndrome.
- Cortisol, Total Your main stress hormone, produced by the adrenal glands. Reflects adrenal function and helps evaluate conditions like Cushing's syndrome or adrenal insufficiency.

Cortisol, 2 Specimens
Labcorp
Not offered
Cortisol is increased in Cushing's disease and decreased in Addison's disease (adrenal insufficiency).
Cortisol, 3 Specimens
Labcorp
Not offered
Cortisol is increased in Cushing's disease and decreased in Addison's disease (adrenal insufficiency).
Cortisol, 4 Specimens
Labcorp
Not offered
Cortisol is increased in Cushing's disease and decreased in Addison's disease (adrenal insufficiency)
Cortisol, 5 Specimens
Labcorp
Not offered
Cortisol is increased in Cushing's Disease and decreased in Addison's Disease (adrenal insufficiency).
Cortisol, 6 Specimens
Labcorp
Not offered
Cortisol is increased in Cushing's disease and decreased in Addison's disease (adrenal insufficiency).
Cortisol, A.M.
Labcorp
Not offered
This test measures the level of cortisol in the blood in the morning when it's typically highest. High levels of cortisol may indicate Cushing's Disease, while low levels could suggest Addison's Disease (adrenal insufficiency), both of which affect your adrenal glands.
Cortisol,LC/MS, Saliva
Labcorp
Not offered
This test measures the level of cortisol in saliva, which can be particularly telling when taken late at night. It's a key tool in screening for Cushing syndrome, a condition where your body makes too much cortisol. If two or more positive results are received, it could confirm Cushing syndrome. This test is also used to check if Cushing disease comes back after treatment.
Cortisol, LC/MS, Saliva, 2 Samples
Labcorp
Not offered
Salivary cortisol level, particularly late-night salivary cortisol (LNSC) level, is useful in screening for endogenous Cushing syndrome. Two or more positive results of LNSC tests may be used to confirm Cushing syndrome. LNSC measurement may also be used to monitor for recurrence of Cushing disease [1].
Cortisol, LC/MS, Saliva, 3 Samples
Labcorp
Not offered
Salivary cortisol level, particularly late-night salivary cortisol (LNSC) level, is useful in screening for endogenous Cushing syndrome. Two or more positive results of LNSC tests may be used to confirm Cushing syndrome. LNSC measurement may also be used to monitor for recurrence of Cushing disease [1].
Cortisol, LC/MS, Saliva, 4 Samples
Labcorp
Not offered
Salivary cortisol level, particularly late-night salivary cortisol (LNSC) level, is useful in screening for endogenous Cushing syndrome. Two or more positive results of LNSC tests may be used to confirm Cushing syndrome. LNSC measurement may also be used to monitor for recurrence of Cushing disease [1].
Cortisol, P.M.
Labcorp
Not offered
This test measures the level of cortisol in the body during the afternoon. High levels of cortisol can indicate Cushing's Disease, while low levels may suggest Addison's Disease (adrenal insufficiency), which affects the adrenal glands.
Cotton, Crude Fibers (o1) IgE
Labcorp
Not offered
This test measures the body's immune response to cotton fibers by checking for specific IgE antibodies in the serum. It's useful for individuals who may have allergic reactions to cotton.
Cotton Seed (k83) IgE
Labcorp
Not offered
This test measures the body's immune response to cotton seed through the detection of specific IgE antibodies. It's crucial for identifying potential allergic reactions to cotton seed, which can be important for individuals showing symptoms of allergies when exposed to cotton seed or related products.
Cottonwood (t14) IgE
Labcorp
Not offered
This test measures the body's immune response to cottonwood pollen by checking the level of specific IgE antibodies in the serum. It's particularly useful for individuals who may be experiencing seasonal allergies, helping to confirm the cause of symptoms.
- Cottonwood (t14) IgE Measures IgE antibodies to cottonwood tree pollen, a common spring allergy trigger.
Cow Dander (e4) IgE
Labcorp
Not offered
This test measures the immune system's response to cow dander helping to identify allergic reactions. It's a quantitative assay used alongside a patient’s medical history to assist in diagnosing allergic diseases.
Cow's Milk (f2) IgE
Labcorp
Not offered
The test measures an individual's allergic reaction to cow's milk by quantifying IgE antibodies. This test is performed in a lab and helps in diagnosing food allergies when combined with other clinical evaluations.
- Cow's Milk (f2) IgE Measures IgE antibodies specific to milk proteins, used to check for a milk allergy.
Coxsackie A Antibodies, Serum
Labcorp
Not offered
Panel currently includes testing against A-2, 4, 7, 9, 10, and 16 antigens. Although there is cross-reactivity among the enteroviruses by CF, most healthy people do not have titers >1:8. Therefore, detectable titers, especially those >1:32, should be considered diagnostic. Confirmed serodiagnosis is made by demonstration of a four-fold change in titers between acute and convalescent sera.
Coxsackie B Virus Antibodies
Labcorp
Not offered
This test detects neutralizing antibodies to coxsackie B virus. PCR testing is preferred for diagnosis of acute infection.
C-Peptide
C-Peptide is a substance produced in the pancreas, released into the bloodstream in equal amounts to insulin. Measuring C-peptide levels helps assess how much insulin the body is producing, which can aid in distinguishing between type 1 and type 2 diabetes or evaluating insulin-producing tumors (insulinomas).
- C-Peptide A byproduct made in equal amounts to insulin when your pancreas produces it. Helps distinguish how much insulin your body is actually making, useful in diabetes evaluation.
