In suspected gout, which analyte would typically be ordered and how would it be affected?

This question centers on the link between gout and high uric acid. Gout is caused by accumulation of monosodium urate crystals that come from uric acid, the end product of purine metabolism, which is normally cleared by the kidneys. When gout is suspected, the test typically ordered is serum uric acid, and it is usually elevated. The elevated uric acid reflects either overproduction or underexcretion by the kidneys, leading to crystal formation in joints. The other analytes aren’t as directly tied to diagnosing gout: urea (BUN) and creatinine relate to kidney function, which can be affected in gout but aren’t diagnostic for it; glucose isn’t related to the crystal-triggering process.
