Kidney Stone Tests

Kidney stone tests help identify why stones form, what type of stone is present, and which risk factors may increase the chance of future stones. This category covers the key urine tests, blood tests, stone analysis methods, and kidney stone risk panels used to evaluate calcium oxalate stones, calcium phosphate stones, uric acid stones, cystine stones, and infection-related struvite stones. Explore detailed guides to the 24-hour urine kidney stone risk test, kidney stone analysis, Litholink testing, recurrent kidney stone panels, and individual markers such as urine calcium, oxalate, citrate, uric acid, sodium, magnesium, phosphorus, pH, urine volume, and supersaturation. You can also learn how blood calcium, blood uric acid, and parathyroid hormone (PTH) testing may uncover metabolic or parathyroid causes of stone formation. Each guide explains what the test measures, how samples are collected, what high or low results may mean, and how factors such as dehydration, high salt intake, hypercalciuria, high oxalate, low citrate, acidic urine, gout, cystinuria, and mineral imbalance can affect kidney stone risk. Whether you are investigating a first stone or recurrent kidney stones, these resources make laboratory results and stone-prevention testing easier to understand.
