Analysis detects genetic variants
CE-IVD validated product ready for IVDR within timeframes and transition periods specified by the IVDR-2022 regulation
CDT (carbohydrate-deficient transferrin) is a lab marker showing the highest specificity for chronic alcohol abuse. CDT values increase significantly with the daily intake of more than 60 g ethanol (the equivalent of 0.75 l wine) per day over a period of two weeks. The values return to normal within two weeks in case of alcohol abstention. This makes CDT an excellent parameter for continuous monitoring in withdrawal programmes or for assessments in forensic or occupational medicine.
Unlike other biochemical parameters like γ-GT or MCV, liver diseases will not cause any false-positive results.
- Automated sample preparation
- 96 samples in 75 minutes
This Chromsystems assay allows for the fast and reliable measurement of CDT in serum using HPLC and UV detection. Automated sample preparation can save a significant amount of time and resources for larger sample batches. 96 samples can be prepared within 75 minutes.
The CDT is displayed as an area percentage of total transferrin, so it remains unaffected by fluctuations in the concentration of transferrin in serum. Optimised chromatographic separation of transferrin isoforms also allows for the reliable detection of known genetic variants.
A manual standard method and one with Pre-mixed Tubes are available as alternatives.
