name
Choriogonadotropin (pregnancy test) [Presence] in Serum by Rapid immunoassay
description
This term was created for, but is not limited in use to, the bioMerieux bioNexia hCG Combo kit, which is intended for the qualitative detection of human chorionic gonadotropin (hCG) in urine [LOINC: 80384-1] or serum to aid in the early detection of pregnancy. The bioNexia hCG Combo assay has a sensitivity of 25 mIU/mL, at which level there is no cross-reactivity interference from the structurally related glycoprotein hormones FSH, LH and TSH, and which allows detection of pregnancy as early as one day after the first missed menses. The assay result should be read 5 minutes after the serum sample is applied to the sample well.

component
Choriogonadotropin (pregnancy test)
property
PrThr = 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.
time
Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
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.

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.
