Calprotectin, Stool
Labcorp
Not offered
This test measures the level of calprotectin, a protein found in white blood cells, in your stool. High levels of calprotectin indicate inflammation in the intestines, which can help diagnose conditions like inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, as well as distinguish these conditions from irritable bowel syndrome (IBS).
Canary Bird Feathers (e201) IgE
Labcorp
Not offered
This test measures the body's allergic response to canary bird feathers by quantifying IgE antibodies in serum, helping to identify allergic reactions to those specific proteins. It's particularly useful for individuals who may be experiencing environmental allergies, helping to confirm the cause of symptoms. It is intended to be used in conjunction with other clinical information to aid in the diagnosis of allergic diseases.
Canary Grass (g71) IgE
Labcorp
Not offered
This test is designed to identify allergic reactions to Canary Grass 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.
Cancer Antigen 125 (CA 125)
Quest
Not offered
CA 125 (Cancer Antigen 125) is a protein that may be elevated in the blood of individuals with certain cancers, most commonly ovarian cancer. It is used to monitor treatment response, detect recurrence, and sometimes assist in diagnosis, although elevated levels can also be seen in non-cancerous conditions like menstruation, endometriosis, and pelvic inflammatory disease.
- Cancer Antigen 125 (CA 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 19-9 (CA 19-9)
CA 19-9 (Cancer Antigen 19-9) is a protein that may be elevated in the blood of individuals with gastrointestinal cancers, particularly pancreatic cancer. It is mainly used to monitor treatment response and disease progression, but it is not specific enough for early cancer detection, as levels can also rise in non-cancerous conditions like pancreatitis or liver disease.
- Cancer Antigen 19-9 (CA 19-9) A tumor marker used mainly to monitor pancreatic cancer, and sometimes other gastrointestinal cancers, rather than to screen for them.

Candida Immune Complex
Labcorp
Not offered
Candida Immune Complexes which form in vivo are comprised of Candida Albicans antigen, anti-Candida IgG antibodies, and complement. The presence of these complexes is an indication of overgrowth of C. albicans in the gut. Candida overgrowth was first described by Brabander and associates in 1957. Diagnosis of the condition has been difficult due to the ubiquitous nature of Candida resulting in the existence of antibodies to it in a large percentage of the normal population. It is also difficult to isolate by culture from stool due to the overgrowth by normal intestinal flora. Symptoms of Candida intestinal overgrowth include bloating, itching, and skin rashes. Lehman and Reiss suggested that the presence of immune complexes to Candida is an objective means of diagnosing the condition. The results of Broughton and Lanson concluded that the marker for Candida immune complexes not only aid in diagnosing intestinal overgrowth, but that levels of complexes decrease during successful treatment.
