Determination of coproporphyrin I and coproporphyrin III in urine by HPLC with fluorescence detection

Popis výsledku v původním jazyce

Objective. To develop a HPLC method for the diagnosis of porphyrias within the laboratory training. Method. We have developed and evaluated a method for the determination of coproporphyrins I and III in urine by high-performance liquid chromatography with fluorescence detection. By using the controller, a gradient program was used to separate selected porphyrins from other interfering compounds. The flow rate was 0.5 mL/min. Coproporphyrins I and III were detected at excitation 394 nm and emission 624 nm. Results. The analytical performance of the method is satisfactory for clinical trials. The intra-assay coefficients of variation were 4.84% and 6.00% for coproporphyrin I and III, respectively. The calibration curve was linear with the tested range 6-460 ug/L for coproporphyrin I and 6-490 ug/L for coproporphyrin III. The recoveries were 92.23% (CV 4.38%) for coproporphyrin I and 99.05% (CV 5.41%) for coproporphyrin III. The preliminary reference range of coproporphyrins I and III in
