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.
[8] [22] The sample can be collected at any time of the day, [23] but the first urine of the morning is preferred because it is more concentrated. [24] To prevent contamination, a "midstream clean-catch" technique is recommended, in which the genital area is cleaned before urinating and the sample is collected partway through the urination.

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 ...
Sample of human urine Urine is a liquid by-product of metabolism in humans and many other animals. In placental mammals , urine flows from the kidneys through the ureters to the urinary bladder and exits the urethra through the penis or vulva during urination .
A blood sample is routinely used to detect ethanol/methanol and ASA/paracetamol intoxication. Various panels are used for screening urine samples for common substances, e.g. triage 8 that detects amphetamines, benzodiazepines, cocaine, methadone, opiates, cannabis, barbiturates and tricyclic antidepressants. [57] Results are given in 10–15 min.
A urine sample, originating from the bladder, is obtainable both voluntarily and taken post-mortem. Notably, urine is less prone to viral infections such as HIV or Hepatitis B in comparison to blood samples. [9] Many drugs exhibit higher concentrations and more prolonged detection in urine compared to blood.
blood in the urine ; loss of bladder control (incontinence) or overactive bladder; (Although, the American Urogynecologic Society does not recommend that cystoscopy, urodynamics, or diagnostic renal and bladder ultrasound are part of initial diagnosis for uncomplicated overactive bladder.) [2] [3] unusual cells found in urine sample;
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 ...
