Why Is This Test Done?

Your healthcare provider may order this test to diagnose or monitor conditions like gout, kidney disease, or to check for metabolic issues. It can also help assess how well your body is processing waste products.

What to Expect Before the Test

You’ll typically have a small needle inserted into your arm to draw blood. Avoid strenuous activity or eating/drinking for 8–12 hours before if instructed, as it may affect results.

What the Results Mean

Results are compared to a general reference range, but individual needs vary. High levels may signal overproduction or kidney problems, while low levels might indicate dehydration or certain genetic conditions.

Common Conditions Monitored

Elevated uric acid is often linked to gout, kidney stones, or metabolic syndrome. Low levels may be associated with rare genetic disorders or fluid loss.

Reference range

INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A

Specimen: plasma

Inform your healthcare provider if you are taking blood thinners. No special preparation required.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test is critical for identifying conditions affecting purine metabolism or kidney function, guiding treatment plans for arthritis, kidney disease, or metabolic disorders.
