The Uric Acid Test Is No Longer Just a Blood Draw
Uric acid, the final breakdown product of purines in your body, can now be measured in blood, urine, and even saliva. That matters because it's not just a gout marker anymore. It's a biomarker tied to kidney disease, cardiovascular risk, preeclampsia, and oxidative stress. And both high and low levels can signal problems, from gout on one end to neurodegenerative disease on the other. The testing landscape has shifted fast. Standard lab tests remain the gold standard for accuracy, but a wave of newer options, including portable biosensors, paper-based strips with smartphone readouts, and saliva tests, are making it possible to monitor uric acid outside the clinic entirely.
