Abstract
A novel technique has been discovered for separating oxalate from urine and other biological fluids. The method involves mixing the fluid with an adsorbent to separate the oxalate from the fluids, washing the adsorbent-oxalate complex, and releasing the oxalate by reacting the complex with alkali. This technique provides accurate results and can easily be run in hospitals and clinical laboratories.
Claims20
A method for separating oxalate from body fluids, which comprises:
- (a) Mixing the body fluid with an adsorbent or a combination of adsorbents,
- (b) Swirling the mixture and allowing the adsorbent to settle, discarding the supernatant,
- (c) Washing the adsorbent by swirling with water, allowing the adsorbent to settle, discarding the supernatant,
- (d) Adding alkali to the adsorbent, mixing, allowing the adsorbent to settle, and decanting the supernatant for use in analyzing for oxalate.
