Porphyrins by Column Test

Print

The Bio-Rad Porphyrins by Column Test provides simple and accurate semi-quantitative determinations of the predominant porphyrins excreted in the urine: coproporphyrins or uroporphyrins.

Specimen preparation involves purification of porphyrins using ion exchange cleanup columns, followed by elution with a strong acid and spectrophotometric measurement. Chromatographic columns are used to purify specimens of interfering substances. This highly specific and sensitive assay operates on a small specimen volume (1.0 mL).
