Urine Crystals
Urine crystals form when minerals and metabolites precipitate out of solution, and the type of crystal helps identify stone risk and metabolic disorders. Calcium oxalate is most common, uric acid crystals accompany gout, triple phosphate (struvite) can indicate infection, and cystine suggests a hereditary disorder. Hydration and dietary changes reduce most crystal formation.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for Urine Crystals. How we verify ranges.
- General guidance, no named sourceNone or fewCommon and usually benign; recurrent crystals plus stones warrant follow-up
- Lab reference intervalNone or fewWhat a lab report flags against. A lab interval is not an optimal target.

Why Urine Crystals matters
Crystal type helps identify kidney stone risk and metabolic disorders. Calcium oxalate is most common; uric acid indicates gout risk; cystine suggests genetic disorder. Hydration reduces most crystal formation.
Which Providers Test Urine Crystals?
Empirical Health is both the cheapest ($190/year) and the most comprehensive (100+ biomarkers) panel that includes Urine Crystals.
3 panels that include it, cheapest first
| Provider | Annual Cost | Total Biomarkers | $/Biomarker |
|---|---|---|---|
| $190 | 100+ | $1.90 | |
| $297 | 100+ | $2.97 | |
| $365 | 100+ | $3.65 |
$/Biomarker is annual cost divided by the panel's advertised biomarker count, not the price of this one test. We track 23 blood test providers (32 plans); 21 of those plans are itemized marker by marker. Compare all of them.
