There are a number of other causes of a raised CDT as detailed below: PEth is moderately correlated with the percentage of carbohydrate‐deficient transferrin (CDT%) indirect test for ethanol (r = 0.59; r = 0.62) 24; poorly correlated with the liver enzyme gamma‐glutamyl transferase (GGT) test (r = 0.34); and uncorrelated with mean corpuscular volume (MCV) (r = 0.09) 18. Phosphatidylethanol (PEth) only forms in the presence of Ethanol, meaning it is a direct marker for alcohol intake. This makes is a more sensitive indicator than existing markers of CDT, LFT and FBC. PEth can be detected for up to a month.
