80619-0Zika virus IgM Ab [Units/volume] in Serum or Plasma by ImmunoassayActive

Term Description

Quantitative analysis of Zika virus IgM antibodies in serum or plasma specimens by immunoassay-based methods. Similar to most EIA tests, results are reported as a ratio of optical densities.

Zika virus IgM antibodies become detectable 4-8 days after the onset of symptoms and persist for months. Serological cross-reactivity is strong between Zika and other flaviviruses, especially Dengue virus. Therefore, positive results for this test are presumptive and should be confirmed by neutralizing antibody testing [LOINC:80620-8]. Negative results for this test on a sample taken during the first week of illness does not rule out infection and the test should be repeated on a convalescent sample.

Part Description

LP200137-0   Zika virus
Zika virus (ZIKV) is a flavivirus transmitted primarily by the Aedes mosquito which was first identified in a sentinel monkey in the Zika forest in Uganda in 1947. Since 2014 it has spread explosively in the Americas where it has infected hundreds of thousands of people. About 80% of those infected are asymptomatic. Common symptoms include fever, headache, rash, arthralgia and conjunctivitis. Since the end of 2015, there has been an increase in ZIKV-associated cases of Guillain-Barre syndrome and a tremendous increase in cases of microcephaly in fetuses and newborns in Brazil, raising worldwide public health concern. Recent predictions are that the mosquito species A. Albopictus, which can hibernate and survive cool temperatures, will carry ZIKV to more temperate areas of North America, Australia and Southern Europe. It is still not clear whether ZIKV in humans increases viral titers enough to trigger a new cycle when an infected person is bitten by a naïve mosquito. Direct human-to-human transmission has been documented to occur perinatally, sexually (primarily through semen), through breastfeeding, blood transfusion and through occupational transmission in the laboratory setting. There are currently no specific anti-viral agents, vaccination or medical prophylaxis available.
