HelpTest ID CRDPP Creatine Disorders Panel, Plasma
Ordering Guidance
For diagnosis of creatine transporter deficiency, order CRDPU / Creatine Disorders Panel, Random, Urine.
Additional Testing Requirements
To diagnose all creatine deficiency syndromes, order CRDPU / Creatine Disorders Panel, Random, Urine in addition to this test.
Necessary Information
Patient's age and sex are required.
Specimen Required
Collection Container/Tube:
Preferred: Lavender top (EDTA)
Acceptable: Green top (sodium heparin), yellow top (ACD)
Submission Container/Tube: Plastic vial
Specimen Volume: 0.5 mL
Collection Instructions: Centrifuge and aliquot plasma into plastic vial. Send plasma frozen.
Forms
1. Biochemical Genetics Patient Information (T602)
2. If not ordering electronically, complete, print, and send a Biochemical Genetics Test Request (T798) with the specimen.
Useful For
Evaluating patients with a clinical suspicion of arginine:glycine amidinotransferase deficiency and guanidinoacetate methyltransferase deficiency using plasma specimens
This test is not useful for the diagnosis of creatine transporter deficiency.
