What is this test?
The urine urate crystals test examines your urine sample under a microscope (using computer-assisted technology) to detect and count amorphous urate crystals. These are tiny crystals formed from uric acid salts that can sometimes appear in urine. The test measures the number of crystals per area in the urine sediment.
How is the test performed?
A urine sample is collected (usually mid-stream) and sent to a laboratory. The sample is spun in a centrifuge to separate solids from liquid, then examined under a microscope using specialized computer software that identifies and counts urate crystals.
Do I need to prepare for the test?
No special preparation is typically required. Your healthcare provider may ask you to stop certain medications that could affect results. It's best to inform your doctor about any medications or supplements you're taking.
Reference range
NCBI: Uric Acid Male 3.5-7.2 mg/dL; Female 2.5-6.8 mg/dLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated urate crystals in urine may indicate: gout (a type of arthritis), kidney stones (uric acid stones), renal dysfunction, or certain metabolic conditions like Lesch-Nyhan syndrome. The test helps differentiate between different types of kidney stones and assess kidney health.
Low or normal levels are generally not concerning and indicate healthy uric acid metabolism and kidney function.
Results should be interpreted by your healthcare provider in conjunction with other tests and your overall clinical condition.
