The medical device EndoMark® H1A kit for endocan

EndoMark® H1A or EMH1A is a ready-to-use sandwich-type immunoassay. It can analyze1 1 to 45 samples, either manually or on an automated platform developed by Biothelis.

This medical device is manufactured by Biothelis, according to European Directive 98/79 / CE.

The endocan measurement is reimbursed by the French Social Security (RIHN, code K305, BHN200)
