LOINC Code


LOINC code81320-4
nameInfluenza virus A H5 Asian RNA [Cycle Threshold #] in Respiratory system specimen by Nucleic acid amplification using primer-probe set H5a
descriptionThis term represents the identification of the Influenza A H5 subtype based on the H5a probe and primer set provided by the Centers for Disease Control and Prevention. "H5a" does not refer to a more specific type of the H5 virus, rather it is the name of one of the two primer and probe sets (the other is H5b) that are used to detect the Influenza A H5 subtype. For presumptive positive identification of the H5 subtype, results for both the H5a and H5b assays should be positive. If one is positive and one is negative, the result is inconclusive for the H5 subtype. Possible specimens include: upper respiratory tract clinical specimens (including nasopharyngeal swabs, nasal swabs, throat swabs, nasal aspirates, nasal washes, and dual nasopharyngeal/throat swabs), and lower respiratory tract specimens (including bronchoalveolar lavage, bronchial wash, tracheal aspirate, sputum, and lung tissue.)

Fully-Specified Name

componentInfluenza virus A H5 Asian RNA
propertyThreshNum  =  Threshold Number
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.
systemRespiratory System Specimen
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

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.

History/Usage

first released
last updated2.75
last change typeMAJ  - change to name field other than Component;
change reasonRelease 2.75: SYSTEM: There are 2 similar system's in LOINC: 1- Respiratory system 2- Respiratory specimen Due to an applied logic, the display in the System axis for 1 is Respiratory (adjective) without specification of sample, specimen, or other specific noun, while 2 is displayed fully as Respiratory specimen. Therefore for now we replaced 1 with Respiratory system specimen, which will affect 83 term. The result is replacing "Respiratory" with "Respiratory system specimen". This is the short approach. The bigger project is to potentially merge data that has either 1 or 2 together. This is a project to pass by the laboratory committee and will involve about 1500 concepts.;
