WebWhat is the normal renal threshold of sodium (measured in millimoles per liter)? 110-130. Of the total serum osmolality, sodium, chloride, and bicarbonate ions normally contribute approximately what percent? 92. The presence of only slightly visible hemolysis will significantly increase the serum level of which of the following electrolytes? WebIncreased erythrocyte protoporphyrin levels may cause iron deficiency anemia, lead Poisoning, sideroblastic anemia, erythropoietic protoporphyria, hemolytic anemia or chronic diseases. Protoporphyrin is converted to heme by the enzyme ferrocheletase. Lead can inhibit this enzyme and protoporphyrin accumulates.

Web• Erythrocyte protoporphyrin (EP) levels, including zinc protoporphyrin (ZPP) and free erythrocyte protoporphyrin (FEP), are useful in differentiating between acute and chronic exposure. EP levels are elevated in patients with chronic exposure to lead and may also be elevated in patients with iron deficiency anemia. WebDec 12, 2024 · The free erythrocyte porphyrin (FEP) test [ 17, 18 ], was, however, based on liquid-liquid extraction (LLE) at acidic pH, which dissociated zinc protoporphyrin (ZnPPIX) to metal-free PPIX during the extraction process.
WebNov 26, 2014 · Zinc protoporphyrin (ZPP) indicates the systemic supply of iron to erythrocytes in bone marrow. Iron-deficient erythropoiesis results in excess formation of ZPP, which can be measured instantly and at low assay cost using portable haematofluorometers.
