77952-0Trypanosoma cruzi Ab [Presence] in Serum, Plasma or Blood by Rapid immunoassayActive

Term Description

There is a post infection window in which antibody concentration is too low to detect, therefore a negative result cannot exclude the possibility of a very recent infection. This term was created for, but not limited in use to, the submitter's Operon Simple Chagas WB (whole blood) test kit, which rapid test that can be performed in a little over 10 minutes.Serum and plasma specimens may also be used.

Part Description

LP14287-4   Trypanosoma cruzi
The kinetoplastid protozoan parasite Trypanosoma cruzi is the organism that causes Chagas disease. It was discovered in 1909 in Brazil by Carlos Chagas. T cruzi is transmitted to mammals, birds, and reptiles by many of the over 130 species of triatomine bugs. T cruzi can be found in the United States, Mexico, Central America, and South America. The highest density of vector diversity of T cruzi is in the western United States where woodrats are its most common reservoir. Other animals that harbor T cruzi include raccoons, skunks, and coyotes. Infection with T cruzi may be mild or asymptomatic, or rarely can be acute with severe inflammation of the heart muscle, the brain, and the lining around the brain. Approximately 8 million people are infected with T cruzi in Mexico, Central America, and South America, of whom 20-30% will develop symptoms and possibly life-threatening disease. T cruzi is visible on thin or thick blood smears during the acute phase of infection. There are also serological tests used to diagnose past or present infection with T cruzi.[https://www.cdc.gov/parasites/chagas/treatment.html] [PMID: 21976603] Source: Regenstrief LOINC

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
