Alternate Names:
Erythrocyte Porphyrin Erythropoietic Protoporphyria (EPP) Free Erythrocyte Porphyrin (FEP) Protoporphyrin Protoporphyrins, Total, Erythrocytes RBC Porphyrins Red Blood Cell Porphyrins X-linked Dominant Protoporphyria (XLDPP or XDP) Description: Establishing a biochemical diagnosis of erythropoietic protoporphyria and X-linked dominant protoporphyria. If the total erythrocyte porphyrin value is 80 mcg/dL or above, the protoporphyrin fractionation assay will automatically be performed. Test Indications:This is the preferred test for assessment for protoporphyria. This test is not suitable for individuals with bullous dermatosis who are in chronic renal failure and unable to provide a urine specimen. Please contact the duty clinical biochemist for more information. Test Approval Requirements: F260-11-02 Biochemistry Approval for Test Referral Form Recommendations: Include a list of medications the patient is currently taking. Patient preparation instructions: Patient should abstain from alcohol for 24 hours. Alcohol suppresses enzyme activity potentially leading to false-positive results if it is ingested within 24 hours of specimen collection |
