Chronic Alcohol Abuse

Carbohydrate-Deficient Transferrin (CDT) is a sensitive marker for chronic alcohol abuse with more than ~ 60g of alcohol per day. In comparison, EtG is a marker with a shorter time frame of alcohol abuse of a maximum of 6 days.  

We offer a range of CDT assays by HPLC as well as an LC-MS/MS assay for the determination of EtG. All solutions are complete and CE-IVD validated.   

  • Assays for HPLC and LC-MS/MS
  • CE-IVD validated solutions for EtG and CDT
