Test ID PUPYU Purines and Pyrimidines Panel, Random, Urine

Secondary ID

41977

Useful For

Evaluating patients with symptoms suspicious of disorders of purine and pyrimidine metabolism

 

Monitoring patients with disorders of purine and pyrimidine metabolism

 

Laboratory evaluation of primary and secondary hyperuricemias

Specimen Type

Urine


Ordering Guidance


This is the 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, or hereditary xanthinuria, order SSCTU / S-Sulfocysteine Panel, Random, Urine.

 

If this test is ordered with SSCTU, then SSCTU will be canceled.
