LP28423-9 West Nile virus
The West Nile Virus (WNV) is an arbovirus that was first identified in the West Nile District of Uganda in 1937. In the fall of 1999, the National Veterinary Services Laboratory (NVLS) isolated WNV in a dead crow in New York City.(http://www.who.int/mediacentre/factsheets/fs354/en/) Over the following ten years, WNV spread throughout the United States, Canada, Mexico and the Carribbean. WNV is usually transmitted through the bite of the Culex mosquito, but can also be spread in blood transfusions, organ transplants, breast milk, intrauterine exposure and laboratory-acquired infections. Birds are the preferred host of WNV, and the American robin is an important amplifier host since it develops enough virus in its serum to infect feeding mosquitoes. Though most infections with WNV are subclinical for humans, between 2005 and 2009 there were 12,975 people infected with WNV, of which 35% had severe cases of neuroinvasive disease and 496 people died. For individuals who are 70 years of age or older, infection with WNV has a 15-29% fatality rate. For infants and immunocompromised patients infected with WNV, the fatality rate is even higher. Diagnosis of WNV is based on clinical symptoms and antibody titers. The IgM antibody-capture enzyme-linked immunosorbent assay (MAC-ELISA) is the key method used to diagnosis WNV in clinical settings. Antibody titers to WNV NS5 are detectable long-term in vivo and can be used to distinguish past infection with WNV from current infection. RNA is usually undetectable in serum after 13.2 days, but on rare occasions, has been found in serum beyond 40 days. Treatment of infection with WNV is mostly supportive. There are no FDA-approved drugs or vaccines available. PMID: 12089283 PMID: 23034323

LP7238-1 Body fld
The LOINC "Body fld" System represents body fluids other than serum, plasma, blood, urine, and cerebrospinal fluid. When a LOINC term with the System "Body fld" is used, the specific specimen source or body fluid type should be reported elsewhere with the result. Where more specific terms for pleural, peritoneal, synovial fluid, etc. exist, we encourage you to use the more specific terms. In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst. "Asp" is used for abnormal fluid collections that are aspirated, while "Body fld" is used for named body fluids, such as synovial fluid or peritoneal fluid, that are not inherently pathologic.

- 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.
