Catalog ID PUPYP Purines and Pyrimidines Panel, Plasma

Important Note

Order: Ref Misc Referral Lab Test

Comment: Purine & Pyrimidines

Note: All orders for this test will undergo Pathology review for medical necessity.

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.
