Parathyroid Hormone (PTH) Test for Kidney Stones: High Calcium, Hyperparathyroidism, and Meaning

Learn how the PTH test helps evaluate kidney stones, including high calcium, primary and secondary hyperparathyroidism, urine calcium, and follow-up testing.

A parathyroid hormone (PTH) blood test helps determine whether a calcium disorder is contributing to kidney stones. The test is most useful when it...

Recurrent Kidney Stone Test Panel: 24-Hour Urine, Blood Tests, Stone Analysis, and Risk

Learn what a recurrent kidney stone test panel includes, from 24-hour urine and blood tests to stone analysis, risk patterns, timing, and follow-up.

Struvite Stone Test: Infection Stone Markers, Urine pH, Bacteria, and Meaning

Learn how struvite stones are tested using stone analysis, urine pH, culture, bacteria, imaging, and follow-up for infection-related kidney stones.

A struvite stone test is not one single laboratory test. Struvite stones are infection stones, so diagnosis usually combines stone analysis, urine culture, urine...

Uric Acid Stone Risk Test: Urine pH, Uric Acid, Volume, and Acidic Urine

Understand uric acid stone risk testing, including acidic urine pH, 24-hour uric acid, urine volume, metabolic causes, result patterns, and follow-up.

A uric acid stone risk test looks mainly at urine pH, urine volume, and uric acid excretion to determine whether the urine is favorable...

Urine Calcium Test for Kidney Stones: High Calcium, Hypercalciuria, and Stone Risk

Understand urine calcium testing for kidney stones, including hypercalciuria ranges, causes, sodium and oxalate effects, stone risk, treatment, and follow-up.

A urine calcium test measures how much calcium is excreted into the urine and helps identify hypercalciuria, one of the most common metabolic risk...

Urine Citrate Test: Low Citrate, Kidney Stone Risk, and Stone Prevention Evaluation

Understand urine citrate testing for kidney stones, including low citrate ranges, causes, calcium stone risk, potassium citrate treatment, pH effects, and follow-up.

A urine citrate test measures citrate excreted in the urine and helps identify hypocitraturia, a common and treatable risk factor for calcium kidney stones....
