  2. Antibiotic sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Antibiotic_sensitivity_testing

    Once a bacterium has been identified following microbiological culture, antibiotics are selected for susceptibility testing. [5] Susceptibility testing methods are based on exposing bacteria to antibiotics and observing the effect on the growth of the bacteria (phenotypic testing), or identifying specific genetic markers (genetic testing). [6]

  3. Laboratory specimen - Wikipedia

    en.wikipedia.org/wiki/Laboratory_specimen

    Some specimen types also require special treatment, such as immediate mixture with an additive, or storage at a certain temperature. [5] After extraction, all specimen containers must be labeled with at least two of the following identifiers (at the time of collection): patient's name, date of birth, hospital number, test request form number ...

  4. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.

  5. Inoculation loop - Wikipedia

    en.wikipedia.org/wiki/Inoculation_loop

    An inoculation loop (also called a smear loop, inoculation wand or microstreaker) is a simple tool used mainly by microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate.

  6. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    Microbial cultures on solid and liquid media. A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions.

  7. Etest - Wikipedia

    en.wikipedia.org/wiki/Etest

    Etest is a quantitative technique for determining the MIC of microoganisms. It is used for a range of Gram-negative and Gram-positive bacteria such as Pseudomonas, [2] [3] Staphylococcus, [4] and Enterococcus species, [5] as well as fastidious bacteria, such as Neisseria and Streptococcus pneumoniae. [1]

  8. Biological specimen - Wikipedia

    en.wikipedia.org/wiki/Biological_specimen

    A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are stored, ideally they remain equivalent to freshly-collected ...

  9. Diagnostic microbiology - Wikipedia

    en.wikipedia.org/wiki/Diagnostic_Microbiology

    The chemical 5-bromo-4-chloro-3-indolyl-beta-D-galactoside is used in the test because N. lactamica can hydrolyze it with the production of β-galactosidase, turning the solution into a blue color. Gamma-glutamyl-p-nitroanilide is added to the solution to indicate whether the bacteria is N. meningitides, which hydrolyzes the molecule with the ...
