Part Descriptions

LP30923-4   Yersinia pestis
Yersinia pestis is a Gram-negative bacterium belonging to the family Enterobacteriaceae. The infectious agent of bubonic plague, it can also cause pneumonic and septicemic plague. All three forms have been responsible for high mortality rates in epidemics throughout human history, for example, the Great Plague and the Black Death, the latter of which accounted for the death of approximately one third of the European population in 1347 to 1353. The role of Y. pestis in the Black Death is debated among historians; some have suggested that the Black Death spread far too rapidly to be caused by Y. pestis. DNA from Y. pestis has been found in the teeth of those who died from the Black Death, however, and medieval corpses who died from other causes did not test positive for Y. pestis. , This suggests that Y. pestis was, at the very least, a contributing factor in some (though possibly not all of) the European plagues.

LP6304-2   HAI
The hemagglutination-inhibition assay (HAI) can be used to identify subtypes of hemagglutinin producing viruses, such as Influenza. HAI can also be used to identify the subtype-specificity of antibodies against the virus. Normally, Influenza's hemagglutinin glycoprotein binds to receptors on the surface of red blood cells, causing them to agglutinate. If antibodies specific to the virus are present in the patient sample, they will bind to the virus, which prevents the virus from binding to the red blood cells and therefore prevents agglutination. To determine which subtype of virus is present, a viral isolate is tested against a series of antibodies with known subtype specificities. Whichever antibody inhibits red cell agglutination identifies the viral subtype. Similarly, antibody specificity is identified by testing the patient sample against known virus subtypes.

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.; Updated Answer list type from NORMATIVE to EXAMPLE because the Answers in the list (Positive, Negative) are only examples of possible answers and not an exclusive list
