  3. Urinalysis - Wikipedia

    en.wikipedia.org/wiki/Urinalysis

    Urine samples of varying color and clarity. Normal urine has a yellow hue, which is primarily caused by the pigment urochrome. The color can range from pale yellow to amber based on the individual's hydration status. Urine can develop a variety of abnormal colors, which may suggest disease in some cases. [26]

  4. Urine protein/creatinine ratio - Wikipedia

    en.wikipedia.org/wiki/Urine_protein/creatinine_ratio

    Urine protein/creatinine ratio is a widely used initial method to estimate daily protein excretion in urine. [1] [2] [3] Since the diagnosis and management of proteinuric renal diseases and the staging of chronic kidney disease depend on accurate identification and quantitation of proteinuria, [4] [1] the implementation of the 24-hour urine collection is the most accurate procedure in practice ...

    en.wikipedia.org/wiki/Urine_test_strip

    A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample.The test can often be read in as little as 60 to 120 seconds after dipping, although certain tests require longer.

  6. Urine test - Wikipedia

    Example of a container used for collecting 24-hour urine samples. This particular container is free of trace metals to allow for accurate measurement of these substances in urine. The techniques used to collect urine specimens vary based on the desired test. A random urine, meaning a specimen that is collected at any time, can be used for many ...

  7. Enzyme multiplied immunoassay technique - Wikipedia

    en.wikipedia.org/wiki/Enzyme_multiplied...

    Enzyme multiplied immunoassay technique (EMIT) is a common method for qualitative and quantitative determination of therapeutic and recreational drugs and certain proteins in serum and urine. [1] It is an immunoassay in which a drug or metabolite in the sample competes with a drug/metabolite labelled with an enzyme, to bind to an antibody. The ...

  8. Urea-to-creatinine ratio - Wikipedia

    en.wikipedia.org/wiki/Urea-to-creatinine_ratio

    At high urine flow rates (greater than 2 ml/min), 40% of the filtered load is reabsorbed, and at flow rates lower than 2 ml/min, reabsorption may increase to 60%. Low flow, as in urinary tract obstruction, allows more time for reabsorption and is often associated with increases in antidiuretic hormone (ADH), which increases the permeability of ...

  9. Microalbuminuria - Wikipedia

    en.wikipedia.org/wiki/Microalbuminuria

    Microalbuminuria can be diagnosed from a 24-hour urine collection (between 30 and 300 mg/24 hours) or, more commonly, from elevated concentration in a spot sample (30 to 300 mg/L). Both must be measured on at least two of three measurements over a two- to three-month period.
