Metanephrines in Urine/Combined analysis - HPLC
Short analysis time < 10 min
Only 1 HPLC column and 1 Mobile Phase for 2020/COMBI and 6000/COMBI
CE-IVD validated product ready for IVDR within timeframes and transition periods specified by the IVDR 2017/746
3-Methoxytyramine
Metanephrine
Normetanephrine
Adrenaline (Epinephrine)
Dopamine
Noradrenaline
Clinical relevance
In addition to catecholamines, their metabolic products such as metanephrine and normetanephrine are also important indicators in the diagnosis of various tumours. They have to be determined in addition to the parameters VMA and HVA in order to prevent the risk of false-positive results.
Product advantages
- Short analysis time of less than 10 minutes
- No changes to setup are needed due to identical column and mobile phase
Chromsystems offers an exceptionally sensitive and reliable combined method for detecting pheochromocytomas with an analysis time of less than 10 minutes in the analysis of metanephrine with catecholamines in urine (6000/COMBI). The highly selective separation column and the optimised mobile phase are used for the analysis of both catecholamines and metanephrines, so no change of the chromatographic system is required. The established specific sample preparation using solid phase extraction guarantees simple and safe handling and reproducible results.
