[Erythrocyte zinc-protoporphyrin/hem ratio--screening test for the detection of iron deficiency and lead exposure. Experience with the Hemofluorometer in Hungary]

Abstract

Increased zinc protoporphyrin/hem ratio (ZP) in erythrocytes caused by iron deficiency and/or lead exposure can be measured very simply and directly using a dedicated instrument, the Hematofluorometer. Clinical value of ZP test in detecting iron deficiency and lead exposure has been demonstrated by the authors in 465 females. Based on the literature and their own favourable experiences, the authors call attention to this useful screening method of preventive and diagnostic importance.
