Crystals that can be found in normal urine include uric acid, monosodium urate, triple phosphate (ammonium magnesium phosphate), calcium oxalate, and calcium carbonate. [124] Crystals can also appear as poorly defined aggregates of granular material, termed amorphous urates or amorphous phosphates (urates form in acid urine while phosphates ...
Normal excretion of uric acid in the urine is 270 to 360 mg per day (concentration of 270 to 360 mg/L if one litre of urine is produced per day – higher than the solubility of uric acid because it is in the form of dissolved acid urates), roughly 1% as much as the daily excretion of urea. [20]
Pigments excreted in urine are partially absorbed by urate sediments (sedimentum lateritium ), which consists of cell debris and sedimented urinary components formed when the acidified urine is stored below room temperature. [2]
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
[citation needed] The urinalysis may show uric acid crystals or amorphous urates. [citation needed] The hypersecretion of uric acid can be detected with a high urine uric acid - creatinine ratio > 1.0, compared to a value of 0.6–0.7 for most other causes of acute kidney failure. [citation needed]
Crystalluria refers to crystals found in the urine when performing a urine test. Crystalluria is considered often as a benign condition and as one of the side effects of sulfonamides and penicillins. The main reason for the identification of urinary crystals is to detect the presence of the relatively few abnormal types that may represent a ...

Urate (C 5 H 4 N 4 O 3) stones, usually ammonium urate (NH 4 ·C 5 H 4 N 4 O 3) or sodium urate monohydrate (Na·C 5 H 4 N 4 O 3 ×H 2 O), form in an acidic to neutral urine. They are usually small, yellow-brown, smooth stones. Urate stones form due to an increased excretion of uric acid in the urine.
