Follow up for abnormal biochemical results suggestive of porphyria
Establishing a molecular diagnosis for patients with porphyria
Identifying variants within genes known to be associated with porphyria, allowing for predictive testing of at-risk family members
Identification of a pathogenic variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for porphyria.
The biochemical testing approach for diagnosis of patients with a suspected porphyria is most effective when done in a thoughtful manner. For recommendations for first-tier biochemical testing, see Porphyria (Acute) Testing Algorithm and Porphyria (Cutaneous) Testing Algorithm in Special Instructions.
The following algorithms are available in Special Instructions:
Custom Sequence Capture and Targeted Next-Generation Sequencing followed by Polymerase Chain Reaction (PCR) and Sanger Sequencing
