1 METANEPHRINES IN URINE EN / OF PLASMA M.B.V. HPLC EN FLUORESCENCENTIE DETECTIE Metanephrines Wat maakt onze Metanephrines reagensset zo uniek en veelzijdig. U kunt kiezen voor: De totale fracties in urine en/of De vrije fracties in urine en/of De vrije fracties in plasma Urine- en plasma controles met alle fractieconcentraties beschikbaar. De urinemethodieken zijn éénvoudig en snel uitvoerbaar. Deze worden het meest toegepast. Bij pathologisch verhoogde waarden worden steeds vaker aanvullend voor nog meer informatie de vrije fracties in plasma bepaald. METANEPHRINES IN URINE Products Product no.
