Test ID PUPYP Purines and Pyrimidines Panel, Plasma
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.
