Abstract:
:Determination of serum oxalate concentration is important for the diagnosis and monitoring of hyperoxalurias, and extends to patients with all types of renal disease. Approximately 5 to 10 ml of blood is required for each test by conventional methods, and the test is not adapted for use in children. We developed a highly sensitive method that limits the volume of blood required for the test. This new and sensitive tool to detect H2O2 can be successfully substituted for the conventional, and expensive, colorimetric reaction to accurately analyze oxalate concentration.
