Uric Acid, Serum or Plasma
Also known as: URIC
Use
The Uric Acid, Serum or Plasma test aids in the diagnosis and monitoring of gout or kidney stones. It is also used for monitoring uric acid levels in patients who are at risk for kidney stone development. Elevated uric acid levels can indicate overproduction or underexcretion of uric acid, leading to conditions such as gout, nephrolithiasis, or other disorders related to purine metabolism.
Special Instructions
The test should be ordered if there is a clinical suspicion of gout or kidney stones, or if there is a need to monitor uric acid levels in patients with conditions predisposing them to these ailments. Ordering should consider patient history and potential drug interactions.
Limitations
The test may show assay interference with negative results when high concentrations of N-acetylcysteine (NAC) are present. Negative interference has also been reported with NAPQI, an acetaminophen metabolite, but only at concentrations expected during acetaminophen overdose. This may impact the accuracy of test results.
