  2. Official Medicines Control Laboratory - Wikipedia

    en.wikipedia.org/wiki/Official_Medicines_Control...

    Official Medicines Control Laboratory (OMCL) is the term coined in Europe for a public institute in charge of controlling the quality of medicines and, depending on the country, other similar products (for example, medical devices). They are part of or report to national competent authorities (NCAs).

  3. Laboratory quality control - Wikipedia

    en.wikipedia.org/wiki/Laboratory_quality_control

    An example of a Levey–Jennings chart with upper and lower limits of one and two times the standard deviation. A Levey–Jennings chart is a graph that quality control data is plotted on to give a visual indication whether a laboratory test is working well.

  4. Calibration curve - Wikipedia

    en.wikipedia.org/wiki/Calibration_curve

    A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration. [1]

  5. Ultraviolet–visible spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet–visible...

    A UV-Vis spectrophotometer is an analytical instrument that measures the amount of ultraviolet (UV) and visible light that is absorbed by a sample. It is a widely used technique in chemistry, biochemistry, and other fields, to identify and quantify compounds in a variety of samples.

  6. Analytical quality control - Wikipedia

    en.wikipedia.org/wiki/Analytical_quality_control

    All analytical procedures should be validated. Identification tests are conducted to ensure the identity of an analyte in a sample through comparison of the sample to a reference standard through methods such as spectrum, chromatographic behavior, and chemical reactivity. [5] Impurity testing can either be a quantitative test or a limit test.

    Blood culture bottle: Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms. [2] Blue ("light blue") Sodium citrate (weak calcium chelator ...

  8. Certified reference materials - Wikipedia

    en.wikipedia.org/wiki/Certified_reference_materials

    Since most analytical instrumentation is comparative, it requires a sample of known composition (reference material) for accurate calibration. These reference materials are produced under stringent manufacturing procedures and differ from laboratory reagents in their certification and the traceability of the data provided.
