Further laboratory testing reveals a normal total serum iron and iron-binding capacity; however, the zinc protoporphyrin level was very high. A urinary screen for porphyrins was positive. WebTesting begins with total erythrocyte porphyrins. If the result is below 80 mcg/dL, it is normal, and testing is complete. If the total erythrocyte porphyrin value is 80 mcg/dL or above, the protoporphyrin fractionation assay will automatically be performed at an additional charge.
