urealyticum and Ureaplasma parvum at Mayo Medical Laboratories.
Useful For: Rapid, sensitive, and specific identification of Ureaplasma urealyticum and Ureaplasma
parvum from genitourinary, reproductive, and lower respiratory sources
Interpretation: A positive PCR result for the presence of a specific sequence found within the
Ureaplasma urealyticum and Ureaplasma parvum ureC gene indicates the presence of Ureaplasma
urealyticum or Ureaplasma parvum DNA in the specimen. A negative PCR result indicates the absence of
detectable Ureaplasma urealyticum and Ureaplasma parvum DNA in the specimen, but does not rule-out
infection as false-negative results may occur due to the following; inhibition of PCR, sequence variability
underlying the primers and/or probes, or the presence of Ureaplasma urealyticum or Ureaplasma parvum
in quantities less than the limit of detection of the assay.

Uric Acid, Random, Urine
Clinical Information: Uric acid is the end-product of purine metabolism. It is freely filtered by the
glomeruli and most is reabsorbed by the tubules. There is also active tubular secretion. Increased levels of
uric acid in the urine usually accompany increased plasma uric acid levels unless there is a decreased
excretion of uric acid by the kidneys. Urine uric acid levels reflect the amount of dietary purines and also
endogenous nucleic acid breakdown. Acute uric acid nephropathy can cause acute renal failure due to uric
acid precipitation within tubules. This is most commonly seen in patients with hematologic malignancies
(eg, lymphoma, leukemia), often after acute lysis of cells by chemotherapy. Less commonly this may be
seen with seizures, treatment of solid tumors, overproduction of uric acid in metabolic disorders such as
Lesch-Nyhan syndrome or decreased uric acid reabsorption in the proximal nephron due to tubular
disorder (Fanconi syndrome).
Useful For: Differentiation of acute uric acid nephropathy from other causes of acute renal failure
Patients who cannot collect a 24-hour specimen, typically small children, a uric acid creatinine ratio can
