Introduction: CgA is the most important biochemical marker for evaluation of NETs. Different assays with different accuracy exist.

Aim(s): To validate three different assays in NET patients.

Materials and methods: We measured CgA in 42 patients using three different assays (Rigshospitalet in-house (RH), NEOLISA and RIA (Euro-Diagnostica)).
