Abstract The development of the standard reference materials of uric acid in frozen serum is introduced. The checking of uniformity, stability test and certified value are systematically studied by LC/ID-MS. The results show that the certified value of the reference material of uric acid in frozen serum is 55.88 mg/kg with the expended uncertainty of 0.74 mg/kg. The uniformity and stability of the reference material of uric acid in frozen serum meet the technical requirements of the standard reference material.
