Learn what acidic and alkaline urine pH results mean, how pH relates to kidney stones and UTI, common causes of high or low pH, and when follow-up testing is needed.

A urine pH test shows how acidic or alkaline urine is. Most routine urinalysis results fall somewhere between about pH 4.5 and 8.0, with...

Urine Protein Dipstick Test: Positive Result, Proteinuria, Kidney Disease, and Meaning

Learn what a positive urine protein dipstick means, how proteinuria relates to kidney disease, common false results, and when uACR, UPCR, or further follow-up is needed.

A urine protein dipstick test is a quick screening test for protein in urine, especially albumin. A positive result can be a sign of...

Urine Specific Gravity Test: High, Low, Hydration, Kidney Concentration, and Meaning

Understand urine specific gravity results, including normal ranges, high and low values, hydration effects, kidney concentration, osmolality, and follow-up.

Urine Urobilinogen Test: High, Low, Liver Disease, Hemolysis, and Meaning

A urine urobilinogen test measures a breakdown product formed when intestinal bacteria process bilirubin from bile. Small amounts normally reach the urine, so a...

24-Hour Urine Kidney Stone Risk Test: Calcium, Oxalate, Citrate, Uric Acid, and Volume

Learn how a 24-hour urine kidney stone risk test measures calcium, oxalate, citrate, uric acid, urine volume, pH, and other factors to guide prevention.

Blood Calcium Test for Kidney Stones: High Calcium, Parathyroid Causes, and Stone Risk

Learn what a blood calcium test means for kidney stones, including high calcium, parathyroid hormone causes, hypercalciuria, follow-up tests, and stone risk.

A blood calcium test helps identify medical conditions that can raise kidney stone risk, especially primary hyperparathyroidism. Most people who form calcium stones do...

Blood Uric Acid Test for Kidney Stones: Gout, Uric Acid Stones, and Stone Risk

Learn how a blood uric acid test relates to gout and kidney stones, why urine pH matters most for uric acid stones, and how high or normal results are interpreted.

A blood uric acid test measures the amount of urate circulating in the bloodstream and can help identify gout, high uric acid production, reduced...

Calcium Oxalate Stone Risk Test: Urine Oxalate, Calcium, Citrate, and Volume

Learn how urine oxalate, calcium, citrate, volume, sodium, and supersaturation are used to assess calcium oxalate stone risk and guide targeted prevention.

A calcium oxalate stone risk test uses urine chemistry to show why calcium oxalate crystals may be forming and which risk factors are most...

Cystine Capacity Test: Cystinuria Monitoring and Cystine Stone Risk

Learn what a cystine capacity test means in cystinuria, how positive and negative results reflect cystine saturation, and how the test helps monitor cystine stone prevention.

A cystine capacity test estimates whether urine is likely to dissolve cystine or allow cystine crystals to grow. It is designed for people with...

Cystine Stone Test: Cystine Levels, Cystinuria, Genetic Risk, and Meaning

Learn how cystine stone testing diagnoses cystinuria, what urine cystine levels mean, how SLC3A1 and SLC7A9 affect genetic risk, and how results guide prevention.

A cystine stone test looks for evidence of cystinuria, an inherited disorder that causes excessive cystine to spill into urine and form recurrent kidney...

Kidney Stone Analysis Test: Stone Composition, Stone Types, and What Results Mean

Learn how kidney stone analysis identifies calcium oxalate, calcium phosphate, uric acid, cystine, struvite, and mixed stones and how results guide prevention.
