The determination of coproporphyrin I and III in human urine using an HPLC with fluorescence detection

Popis výsledku v původním jazyce

The determination of selected porphyrins, especially of coproporphyrin I and III is presently the most reliable direct approach to the screening of porphyrias. An HPLC method for the simultaneous measurement of coproporphyrin I and III in urine samples has been developed and evaluated. Separation of coproporphyrin I and III from interfering substances was achieved on reversed phase HPLC with gradient elution and fluorescence detection. Analytical performance of this method is satisfactory for both coproporphyrin I and coproporphyrin III: the intra-assay and inter-assay coefficients of variation were below 10 %. Quantitative recoveries from spiked urine were between 85.0 and 101.1 %. The limit of detection was 3.0 and 2.3 ug/L, respectively. The preliminary reference ranges of coproporphyrin I and III in a group of donors are 5.0 51.6 ug/L (0.59 3.20 ug/mmol of creatinine) and 14.9 65.4 ug/L (0.98 8.21 ug/mmol of creatinine). The presented method is inexpensive and suitable for screenin
