For Analyses in Biological Materials


Program operation:

G-EQUAS is open to all interested laboratories worldwide. We perform two QC-schemes per year – one in spring and one in autumn. Interested Laboratories can enrol in the program by filling out the registration form, which will automatically be submitted to our office. Once we receive a subscription request, we will assign a Lab-ID and a password for ordering and reporting results. Please note that you always have to use your Lab-ID for any contact or correspondence (for easier identification purpose).
