Test ID: UPGC
Uroporphyrinogen III Synthase (Co-Synthase) (UPG III S), Erythrocytes
Specimen Type 
Describes the specimen type needed for testing
WB Heparin
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
All porphyrin tests on erythrocytes can be performed on 1 draw tube.
Container/Tube: Green top (heparin)
Specimen Volume: Full tube
Collection Instructions:
1. Patient should abstain from alcohol for 24 hours.
2. Immediately place specimen on wet ice.
Additional Information: Include a list of medications the patient is currently taking.
Forms: New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instructions.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
3 mL
