  2. 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.

  3. Multiplex ligation-dependent probe amplification - Wikipedia

    en.wikipedia.org/wiki/Multiplex_ligation...

    Example of exon deletions detected by Multiplex ligation-dependent probe amplification in a Duchenne muscular dystrophy patient. MLPA quantifies the presence of particular sequences in a sample of DNA, using a specially designed probe pair for each target sequence of interest.

  4. ELISA - Wikipedia

    en.wikipedia.org/wiki/ELISA

    As an analytical biochemistry assay and a "wet lab" technique, ELISA involves detection of an analyte (i.e., the specific substance whose presence is being quantitatively or qualitatively analyzed) in a liquid sample by a method that continues to use liquid reagents during the analysis (i.e., controlled sequence of biochemical reactions that will generate a signal which can be easily ...

  5. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    The amount of labelled antibody on the site is then measured. It will be directly proportional to the concentration of the analyte because the labelled antibody will not bind if the analyte is not present in the unknown sample. This type of immunoassay is also known as a sandwich assay as the analyte is "sandwiched" between two antibodies.

  6. Molecular diagnostics - Wikipedia

    en.wikipedia.org/wiki/Molecular_diagnostics

    Advances in molecular biology have helped show that some syndromes that were previously classed as a single disease are actually multiple subtypes with entirely different causes and treatments. Molecular diagnostics can help diagnose the subtype—for example of infections and cancers—or the genetic analysis of a disease with an inherited ...

  7. Antibiotic sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Antibiotic_sensitivity_testing

    Traditional techniques typically take between 12 and 48 hours, [6] although it can take up to five days. [28] In contrast, rapid testing using molecular diagnostics is defined as "being feasible within an 8-h(our) working shift". [6] Progress has been slow due to a range of reasons including cost and regulation. [40]

  8. Bioassay - Wikipedia

    en.wikipedia.org/wiki/Bioassay

    If the measured response is binary, the assay is quantal; if not, it is quantitative. [3] A bioassay may be used to detect biological hazards or to give an assessment of the quality of a mixture. [4] A bioassay is often used to monitor water quality as well as wastewater discharges and its impact on the surroundings. [5]

  9. Bioanalysis - Wikipedia

    en.wikipedia.org/wiki/Bioanalysis

    Initially, nonspecific assays were applied to measuring drugs in biological fluids. These were unable to discriminate between the drug and its metabolites; for example, aspirin (c. 1900) and sulfonamides (developed in the 1930s) were quantified by the use of colorimetric assays. Antibiotics were quantified by their ability to inhibit bacterial ...
