The Fortress Diagnostics Oxalate assay is intended for the quantitative determination of Oxalate in human urine by Enzymatic Colorimetric method. It measures soluble calcium oxalate which gives rise to calcium oxalate crystalluria and the stone formation in the urinary tract that is considered the most important factor in urolithiasis. Oxalate in urine may increase as an end-product of intermediary metabolism or from dietary sources.  A decreased excretion in the urine is associated with hyperglycinemia and hyperglycinuria. An increased excretion could be due to increased ingestion of oxalate rich diet, oxalate precursors, metabolic defects or to the absorption of oxalate in several gastrointestinal disorders involved with fat malabsorption.
