Part Descriptions

LP16041-3   Aztreonam
Aztreonam (Azactam®) is a monocyclic beta-lactam antibiotic (a monobactam) originally isolated from Chromobacterium violaceum. It is resistant to some beta-lactamases, but is inactivated by extended-spectrum beta-lactamases. Aztreonam is effective against gram-negative bacteria, including Pseudomonas aeruginosa. It is not effective against gram-positive bacteria or anaerobes. Aztreonam has to be administered intravenously, as the compound is poorly absorbed when given orally. Side-effects include reactions at the injection site, diarrhea and other gastro-intestinal symptoms. There is limited cross-reactivity between aztreonam and other beta-lactam antibiotics, and it is generally considered safe to admininister aztreonam to patients allergic to penicillin.

LP16041-3   Aztreonam
A monocyclic beta-lactam antibiotic originally isolated from Chromobacterium violaceum. It is resistant to beta-lactamases and is used in gram-negative infections, especially of the meninges, bladder, and kidneys. It may cause a superinfection with gram-positive organisms.

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
