LAB3360
Specimen Type
UrineOrdering Guidance
This is recommended screening test for the initial workup of a suspected disorder of purine and pyrimidine metabolism, particularly when clinical features are nonspecific, and includes measurement of purines, pyrimidines, uric acid, and S-sulfocysteine. If the clinical features are suggestive of molybdenum cofactor deficiency, isolated sulfite oxidase deficiency, and hereditary xanthinuria, order SSCTU / S-Sulfocysteine Panel, Urine.
If this test is ordered with SSCTU, then SSCTU will be canceled.
