Carbohydrate-deficient Transferrin (CDT) -

CDT typically normalizes within several weeks of abstinence of alcohol use. However, it is important to recognize that there are other causes of abnormal CDT levels, which include congenital disorders of glycosylation and other genetic and nongenetic causes of acute or chronic liver disease.

CDT testing alone is not recommended for general screening for alcoholism; however, when combined with other methods ie, gamma-glutamyltransferase, mean corpuscular volume, patient self-reporting, ethylglucuronide analysis , clinicians can expect to identify the majority of patients who consume a large amount of alcohol.

Specimen Specimen Type Serum. Home Laboratory Diagnostics Plasma Proteins Plasma Protein Assays N Latex CDT Assay. N Latex CDT Assay Highly specific screening for detection of chronic alcohol abuse.

Compared to other markers, CDT offers superior sensitivity and specificity: 1,2 CDT is seemingly unaffected by liver diseases other than those induced by alcohol abuse except biliary cirrhosis and chronic active hepatitis.

CDT is not influenced by common chronic diseases or medication. CDT indicates the effectiveness of alcohol detoxification much earlier than gamma-glutamyl transferase or erythrocyte mean corpuscular volume, for example.

Previous population-based studies measuring CDT by ion-exchange chromatography and immunoassay found several patient characteristics, including gender, a high BMI and an insulin-resistant phenotype high triglycerides and low HDL-cholesterol were associated with reduced sensitivity of the CDT response to alcohol [ 8 , 10 ].

In contrast, more recent studies that quantified CDT using the standardized HPLC method did not find any clinically significant differences in CDT in relation to gender or BMI [ 21 ].

The authors concluded that the earlier findings were related to the analytical techniques used for measurement of CDT, and that adjustment of reference intervals in relation to gender or BMI was not required [ 3 , 21 ].

However, a major limitation of these studies was the low or unclear number with confirmed heavy drinking. Reporting CDT as relative amount of total transferrin concentration rather than an absolute value has improved sensitivity and specificity of the assay [ 22 ].

Introduction of this method was expected to negate many of the factors attributed to gender e. This would be in keeping with previous findings that women express higher CDT levels under basal conditions, but produce less in response to heavy drinking [ 26 , 27 ].

The current study extends these findings by confirming the results in a larger group of subjects with confirmed heavy alcohol consumption and by showing that the effect of BMI is independent of other clinical variables.

Currently little is known regarding the process and elimination kinetics of CDT from the circulation and thus the mechanisms responsible for this effect are unclear, but may relate to altered elimination in the presence of renal failure [ 28 ].

Chronic kidney disease does not appear to cause an increase in the baseline levels of CDT in subjects without hazardous drinking [ 29 ]. Similarly, non-enzymatic glycation of transferrin, a process that may occur in uremia [ 28 ] and diabetic subjects [ 30 ] does not appear to interfere with HPLC-based CDT measurement [ 31 ].

The reasons underlying these findings remain unclear. Transferrin is synthesised, glycosylated and secreted by the liver and the rate of transferrin synthesis is reduced in cirrhotic patients [ 36 ].

Further studies with larger numbers of well-characterised patients, who consume heavy amounts of alcohol, are required to further assess factors which impact on the sensitivity of this assay.

Elevated Energy healing methods transferrin Carbkhydrate-deficient levels are used as a Cabrohydrate-deficient in order to screen Transferrin chronic alcohol abuse. Transferrin Tf variants can impair methods to measure elevated Carbohydrate-deficieng Carbohydrate-deficient Transferrin (CDT) such as high-performance liquid chromatography HPLC. We present a Tf variant affecting the second glycosylation site of Tf and the complications it causes in diagnosing alcoholism. A blood sample from a patient with suspected alcohol abuse was analyzed with HPLC, isoelectric focusing, electrospray ionization time-of-flight mass spectrometry ESI-TOF-MSimmunoprecipitation and SDS-Page. Sanger sequencing of Tf was performed to detect Tf mutations. HPLC, SDS-Page and IEF showed a distinctly increased disialo-Tf fraction while the tetrasialo-Tf fraction was decreased, ESI-TOF-MS confirmed these results.
