Hi, I have a low porphobilinogen test after the Zhang protocol and Wahls diet to treat CPN(Chronic Fatigue Syndrome)) for 2 months. Awful symptoms led me to have this test done. Is this porphyria?
Porphobilinogen concentration was below sensitivity of the assay, 0.5 mg/L. Therefore the result was <1.1 mg/g creatinine. This result was calculated by dividing 0.5 mg/L by the creatinine concentration in g/L
