    en.wikipedia.org/wiki/Vanillylmandelic_acid

    VMA is found in the urine, along with other catecholamine metabolites, including homovanillic acid (HVA), metanephrine, and normetanephrine.In timed urine tests the quantity excreted (usually per 24 hours) is assessed along with creatinine clearance, and the quantity of cortisols, catecholamines, and metanephrines excreted is also measured.

    en.wikipedia.org/wiki/5-Hydroxyindoleacetic_acid

    5-HIAA is tested by 24-hour urine samples [1] combined with an acidic additive to maintain pH below 3. Certain foods like pineapple, kiwi, banana, walnuts and drugs such as acetaminophen, nicotine or caffeine are known to interfere with the measurement.

  4. Catecholamine - Wikipedia

    If proteinuria is persistently detected by dipstick testing, a 24-hour urine collection can be performed to obtain an accurate measurement of protein levels; alternatively, protein excretion can be estimated from the urine protein/creatinine ratio of a single specimen. Measuring the amount of protein in the urine helps to distinguish between ...

  8. 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 ...
