Part Description

LP14252-8   Toxoplasma gondii
Toxoplasma gondii is an intestinal coccidium that multiplies within cats as definitive hosts as well as within many other mammals and birds as intermediate hosts. T. gondii reproduces sexually only in cats. It infects the intestinal epithelium and produces oocysts which are shed in the feces. Humans acquire infections most often by consumption of undercooked meat containing tissue cysts or food contaminated by cat feces. Less than 0.1 percent of human cases are acquired congenitally. Toxoplasmosis is minor and self-limiting in immunocompetent individuals who may be asymptomatic or present with fever, lymphadenopathy, muscle aches and headache. Toxoplasma may manifest as encephalitis in immunosuppressed individuals including patients with acquired immune deficiency syndrome (AIDS) and may lead to coma or death. T. gondii often infects the brain and retina in congenitally infected children. Mild symptoms include slightly diminished vision while severely diseased children exhibit a pattern of retinochoroiditis, hydrocephalus, convulsions and intracerebral calcifications. Ocular disease may also occur. Toxoplasma is diagnosed through serology and upon histologic examination of tissues. Prevention includes thorough cooking of meat and proper management of cats. Sulfadiazine and pyrimethamine can be used to treat acute cases. [NCBI Books:NBK7627] 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.
Order vs. Observation
Both
