  2. Urinalysis - Wikipedia

    en.wikipedia.org/wiki/Urinalysis

    The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

  3. Urine urea nitrogen - Wikipedia

    en.wikipedia.org/wiki/Urine_urea_nitrogen

    UUN is determined from 24-hour urine collection. Along with UUN, values for BUN, protein content of diet, enteral or parenteral nutrition, and notable outputs other than urine (gastric residual, fistula output, drainages) are needed to calculate nitrogen balance. Nitrogen Balance = Protein intake/6.25- (UN + 4*) * For average loss via sweat and ...

  4. Nitrogen balance - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_balance

    Nitrogen loss occurs largely through urine in the form of urea, as well as through faeces, sweat, and growth of hair and skin. Blood urea nitrogen and urine urea nitrogen tests can be used to estimate nitrogen balance.

    Reference ranges for urine tests are described below: Measurement Lower limit Upper limit Unit Urinary specific gravity: 1.003 [1] [2] 1.030 [1] [2] g/mL Urobilinogen:

  6. Urine test - Wikipedia

    en.wikipedia.org/wiki/Urine_test

    Contemporary urine testing uses a range of methods to investigate the physical and biochemical properties of the urine. For instance, the results of the routine urinalysis can provide information about the functioning of the kidneys and urinary system; suggest the presence of a urinary tract infection (UTI); and screen for possible diabetes or ...

  7. Assessment of kidney function - Wikipedia

    en.wikipedia.org/wiki/Assessment_of_kidney_function

    Abnormal kidney function may cause too much or too little urine to be produced. The ability of the kidneys to filter protein is often measured, as urine albumin or urine protein levels, [2] measured either at a single instance or, because of variation throughout the day, as 24-hour urine tests. [citation needed]

  8. Urea-to-creatinine ratio - Wikipedia

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

    In medicine, the urea-to-creatinine ratio (UCR [1]), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea (mmol/L) and creatinine (Cr) (μmol/L). BUN only reflects the nitrogen content of urea (MW 28) and urea measurement reflects the whole of the molecule (MW 60), urea is just over twice BUN (60/28 ...

    Urine also contains antibodies, which can be used in diagnostic antibody tests for a range of pathogens, including HIV-1. [35] Urine after four months of storage (note the color and turbidity change compared to fresh human urine). During storage, the urea in urine is rapidly hydrolyzed by urease, creating ammonia.
