nameEpstein-Barr virus-encoded RNA 1 [Presence] in Tissue by Probe
descriptionThis term is used for the detection of nuclear Epstein-Barr virus-encoded RNA 1 (EBER1) by in situ hybridization on tissue. Presence of EBER1 indicates a latent EBV infection. EBV encodes two small nuclear RNAs, EBER1 and EBER2, which are the most abundant viral transcripts in latently infected cells. They are non-polyadenylated and thus not translated into protein. Their function is to inhibit interferon-mediated antiviral effects and apoptosis. Since they are expressed at high levels (around a million copies per latently infected cell), they are considered to be an ideal marker of latent EBV infection. In situ hybridization targeting one or both EBERs is used to determine whether a biopsied tumor is EBV-related.

Fully-Specified Name

componentEpstein-Barr virus-encoded RNA 1
propertyPrThr  =  Present or threshold:  The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold.
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.
systemTiss  =  Tissue, unspecified
scaleOrd  =  Ordinal:  Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive.
methodProbe  =  DNA Nucleic Acid Probe

Associated Observations

LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.

last change typeMIN  - change to field other than name
change reasonThe 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.
