Part Descriptions

LP16237-7   Penicillin G
A penicillin derivative commonly used as sodium or potassium salts in the treatment of a variety of infections. It is effective against most gram-positive bacteria. It has also been used as an experimental anti-convulsant because of its actions on gamma-aminobutyric acid mediated synaptic transmission. Source: National Library of Medicine, MeSH 2006

LP6300-0   Gradient strip
A gradient strip is a reagent strip that contains a predefined concentration gradient of a specific antibiotic or combination of antibiotics that is used for antimicrobial susceptibility testing (AST) and antimicrobial resistance detection (ARD).
For AST, the result is reported in terms of the minimum inhibitory concentration (MIC) of a specific antimicrobial that prevents the visible growth of bacteria. In LOINC, the "Gradient strip" method is used for AST gradient strips that result in an MIC result.
For ARD, the result is reported as the presence or absence of a specific enzyme or other mechanism that confers resistance, which is determined based on comparing the inhibitory concentration (IC) of a specific antimicrobial with the IC of that antimicrobial plus a resistance inhibitor. In LOINC, the "Gradient strip ARD" method is used for ARD gradient strips, which are not intended for determining individual MIC values. Source: Regenstrief LOINC

Change Reason
Feb 2016-removed "E-test" from the short and long names because the "ETEST" name is trademarked; Assigned COMMON_TEST_RANK and COMMON_SI_TEST_RANK of 1641 since LOINC 23925-1 was deprecated and mapped to this term as well as LOINC 7042-5.
