Protoporphyrins, Fractionation, Whole Blood
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Establishing a biochemical diagnosis of erythropoietic protoporphyria
Differential diagnosis of chronic intoxication from exposure to a variety of causes including heavy metals and chemicals
Differential diagnosis in some cases of iron-deficiency anemia
There are 2 test options: whole blood (PPFE / Protoporphyrins, Fractionation, Whole Blood) and washed RBCs (PPFWE / Protoporphyrins, Fractionation, Washed Erythrocytes). The whole blood option is easiest for clients but requires that the specimen arrive at Mayo Medical Laboratories within 72 hours of draw. When this cannot be ensured, washed RBCs should be submitted.
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
Includes separate quantitation of zinc protoporphyrin and free protoporphyrin. Abstinence from alcohol is essential for at least 24 hours as alcohol suppresses enzyme activity, potentially leading to falsely increased results.
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
The following algorithms are available in Special Instructions:
-Porphyria (Acute) Testing Algorithm
-Porphyria (Cutaneous) Testing Algorithm
Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
High-Performance Liquid Chromatography (HPLC) with Fluorescence Detection
Includes separate quantitation of zinc protoporphyrins and free protoporphyrins.
Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name
