LP16715-2   HIV 1+2
Two types of human immunodeficiency viruses (HIV) have been characterized: HIV-1 and HIV-2. HIV-1 was initially discovered in the early 1980s and thought to be the sole causative agent of HIV infections and ultimately AIDS. In 1986, HIV-2 was isolated and also found to cause AIDs. HIV-1 is more virulent and the predominant cause of the HIV infections worldwide. HIV-2 is poorly transmitted and is primarily concentrated in West Africa.

Presently (2012), HIV-1 strains are divided into four groups, including group M (major) with subtypes A through K, group O (outlier), group N (non-M or O), and group P. HIV-2 is divided into subtypes A through E. Occasionally, two viruses of different subtypes can "cross react" and blend their genetic material to create a new hybrid HIV virus. However, many of these new strains do not survive for long. Studies have also shown that the core proteins of HIV-1 and HIV-2 display frequent cross-reactivity whereas the envelope proteins are more type-specific. Source: Regenstrief LOINC

Change Reason
Updated system from Ser to Ser/Plas; 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.

56888-1 HIV 1+2 Ab+HIV1 p24 Ag [Presence] in Serum or Plasma by Immunoassay

Part Descriptions

LP96332-9   HIV 1+2 Ab+HIV1 p24
This test detects HIV-1 core protein, p24, antigen and/or HIV-1 groups M and O Ab and/or HIV-2 Ab in serum or plasma as one combined positive or negative result based on a signal to cut-off (S/CO) value of 1.00. The p24 antigen can be detected in HIV infected persons before seroconversion, thus reducing the window of non-detectability in early infection. Viral transmembrane proteins (TMP) are among the first to appear at seroconversion and remain strong throughout the asymptomatic and symptomatic stages of HIV infection. They are the principle target of HIV antibody tests. Source: Regenstrief Help

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.
