76772-3Plasmodium falciparum Ag [Presence] in Blood by Rapid immunoassayActive

Term Description

Detects Plasmodium falciparum specific histidine rich protein-2 (Pf. HRP-2) in whole blood samples. Pf. HRP-2 is a water soluble protein that is release from parasitized erythrocytes of infected individuals and is specific to P. falciparum species. This term was created for, but not limited in use to, the Nova Century Scientific Rapid test for P. Falciparum Malaria kit, which can deliver results within 30 minutes once the kit has been brought to room temperature.

Part Descriptions

LP14839-2   Plasmodium falciparum
Four species of the Plasmodium protozoa are considered true parasites of humans as they use humans almost exclusively as a natural intermediate host: P. falciparum, P. vivax, P. ovale and P. malariae. Malaria today is usually restricted to tropical and subtropical areas and altitudes below 1,500 m., although in the past malaria was endemic in much of North America, Europe and even parts of northern Asia, and today is still present on the Korean peninsula. However, this present distribution could be affected by climatic changes and population movements. P. falciparum is the most prevalent species and responsible for the most morbidity and mortality worldwide. Early detect is of paramount importance due to the incidence of cerebral malaria and drug resistance. Malarial infections caused by P. falciparum are the most likely to progress to severe, potentially fatal forms with central nervous system involvement (cerebral malaria), acute renal failure, severe anemia, or acute respiratory distress syndrome.[CDC] Source: Regenstrief LOINC, CDC

LP20149-8   Plasmodium
Malaria is a parasitic disease that is passed from one human to another by the bite of an infected Anopheles mosquito with one of four protozoan parasites: Plasmodium falciparum, vivax, malariae or ovale. The parasites enter the bloodstream and infect red blood cells where they multiply and infect more red blood cells. Symptoms usually occur 10 days to 4 weeks after infection and include anemia, high fevers, shaking chills, muscle pain, and nausea. Antimalarial agents used to treat malaria include Quinine, Quinidine, Mefloquine, Chloroquine, and Hydroxychloroquine. The effectiveness of the agents depends on which phase or phases of the Plasmodium life cycle is interrupted. In most cases, treatment outcome is expected to be good except in cases of a p. falciparum infection. Adverse effects from antimalaria medications include vomiting, diarrhea, headaches, cardiac arrhythmias, EKG abnormalities, deafness, damage to liver and kidney and muscle weakness. Source: NMS labs

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.
