Catalog ID PUPYP Purines and Pyrimidines Panel, Plasma
Useful For
Evaluating patients with symptoms suspicious for disorders of purine and pyrimidine metabolism
Monitoring patients with disorders of purine and pyrimidine metabolism
Laboratory evaluation of primary and secondary hyperuricemias
Assessing tolerance for fluoropyrimidine drugs used in cancer treatment
Aiding in the diagnosis of individuals with suspected dihydropyrimidine dehydrogenase deficiency
Ordering Guidance
The preferred test to rule-out inherited disorders of purine and pyrimidine metabolism is PUPYU / Purines and Pyrimidines Panel, Random, Urine.
This test does not evaluate succinyladenosine. If succinyladenosine analysis is needed, order PUPYU / Purines and Pyrimidines Panel, Random, Urine.
Necessary Information
Patient's age is required.
