This product is manufactured by BioVision, an Abcam company and was previously called K663 Oxalate (Oxalic Acid) Colorimetric Assay Kit. K663-100 is the same size as the 100 test size of ab196990.

Oxalate (C₂O₄^2-), in the form of Oxalic acid is present in many foods and beverages (e.g. spinach, tea etc.). It accumulates in many plant tissues and play role in regulating pH, osmosis and calcium storage. In animals, oxalate is either absorbed from dietary intake or produced from glycolate metabolism in liver. Under normal conditions, the daily oxalate load can be excreted by kidney. However, hereditary defects can cause an increased level of oxalate, which leads to hyperoxaluria and results in the formation of kidney stones. Therefore, measurement of oxalate level is useful for the prevention, diagnosis and monitoring of kidney stones.
