WebApr 13, 2024 · Total Plasma Porphyrins. Total plasma porphyrin analysis is useful as a confirmatory test. Plasma porphyrin testing can be used to help differentiate VP from other porphyria types, identify protoporphyria, and monitor PCT. Erythrocyte Porphyrins Erythrocyte porphyrin analysis is used as a first-line test in the diagnosis of protoporphyria. 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.
WebIn addition, it can be used for evaluation of iron-deficiency anemia and chronic lead intoxication. Testing 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 ... WebThe relationship between zinc protoporphyrin (ZPP) and total erythrocyte protoporphyrin, measured as "free" erythrocyte protoporphyrin (FEP), was determined in 194 adult subjects with different occupational and non-occupational lead exposures. Furthermore, the ZPP-FEP comparison was considered with …

WebFinally, at month 23, urine and plasma porphyrin levels were reduced to 271 nmol/mmol and 26 nmol/L (83% and 91% reductions compared to baseline), close to levels observed after BMT. 5 During the course of treatment, total erythrocyte porphyrins levels were moderately reduced (8.7 mmol/L at baseline, 7.3 mmol/L at month 23; 16% decrease) .
WebBecause laboratory methods and terminology are inconsistent, measurement of total erythrocyte protoporphyrin is preferred for initial screening, followed, if elevated, by fractionation of free and zinc protoporphyrin. Plasma porphyrins are more light sensitive and often less elevated than in other cutaneous porphyrias, especially with mild disease.
