Clinical Significance
Giardiasis is an important human intestinal disease in most areas of the world and giardia lamblia is the most frequently identified parasite in the U.S. The giardia antigen test is the most sensitive method to detect this agent. This test may be useful to physicians whose patient a) lives in or has traveled to an area where giardia incidence is high, b) is a child c) during seasons of highest giardia incidence or d) has other risk factors as described in MMWR Surveillance Summaries from January 28, 2005.
CRYPTOSPORIDIOSIS (CRYPTOSPORIDIUM OR CRYPTO) CAUSES WATERY DIARRHEA. ALTHOUGH CRYPTO CAN AFFECT ALL PEOPLE, SOME GROUPS ARE LIKELY TO DEVELOP MORE SERIOUS ILLNESS. FOR PEOPLE WITH WEAKENED IMMUNE SYSTEMS, SYMPTOMS CAN BE SEVERE AND COULD LEAD TO SEVERE OR LIFE-THREATENING ILLNESS. EXAMPLES OF PEOPLE WITH WEAKENED IMMUNE SYSTEMS INCLUDE THOSE WITH AIDS; THOSE WITH INHERITED DISEASES THAT AFFECT THE IMMUNE SYSTEM; AND CANCER AND TRANSPLANT PATIENTS WHO ARE TAKING CERTAIN IMMUNOSUPPRESSIVE DRUGS
