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

LOINC Code


LOINC code80619-0
nameZika virus IgM Ab [Units/volume] in Serum or Plasma by Immunoassay
descriptionQuantitative 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.

Fully-Specified Name

componentZika virus Ab.IgM
propertyACnc  =  Arbitrary Concentration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemSer/Plas
    Ser  =  Serum
    Plas  =  Plasma
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
methodIA  =  Immunoassay:  Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage.
