QuantiQuik™ Oxalate Quick Test Strips, BioAssay Systems

Direct determination of oxalate concentrations in biological samples.

• Fast and sensitive: use of 10 µl sample, semi-quantitative measurement between 0 to 1.5 mg/dl or 0 to 170 µm (undiluted) oxalate
• Method: visual
• Samples: serum, plasma, urine, and more

Oxalate, or oxalic acid, is a metabolic breakdown product of the Kreb's cycle in eukaryotes and the glyoxylate cycle in other microorganisms. Typically present in the urine of humans and other mammals, oxalate concentration can be used as a measure of kidney function. A high level of oxalate is an indicator for kidney stones, which are primarily made of the insoluble salt calcium oxalate. Measuring oxalate is more accurate than measuring calcium as a marker for kidney stones because calcium is excreted at high concentrations even in normal urine.

BioAssay Systems QuantiQuik™ oxalate quick test strips are based on the enzymatic oxidation of oxalate coupled with a color reaction in one step. The intensity of product color is directly proportional to the oxalate concentration in the sample.
