Intermittent or “binge” drinking can increase CDT levels. The extent to which this occurs is dependent on the frequency of “binges” and the amount of alcohol consumed on each occasion. Someone drinking 200-300 g alcohol two days a week, but abstaining on the other days, could have a CDT level of 1.5-3%.

Can CDT test detect binge drinking?

The carbohydrate-deficient transferrin (CDT) is an alcohol biomarker test. 1 It can be used to detect if someone is a binge drinker or a daily heavy drinker (four or more drinks a day). It can even be used to determine if an alcoholic has had a relapse.

How quickly do CDT levels rise?

According to a publication available from the National Institute of Alcohol Abuse and Alcoholism CDT levels appear to elevate after consuming 60-80 grams of alcohol per day (approximately 4 to 6 440ml cans of fosters) for a period of 2 or 3 weeks and CDT levels will normalize with a mean half-life of 2 to 4 weeks ...

What can affect CDT levels?

Results: There is evidence that %CDT levels are affected by alcohol use, end-stage liver disease, and genetic variants. In addition to these three factors, total CDT levels (CDTect) are also affected by factors that raise transferrin levels such as iron deficiency, chronic illnesses, and menopausal status.

How can I improve my CDT levels?

Usually, consumption of 50–60 g of alcohol per day chronically (for at least 2 or 3 weeks) increases CDT. The half-life of CDT is usually 14–17 days; values return to normal 3 or 4 weeks after abstinence.

How far back can a CDT test detect alcohol?

Transferrin remains in the circulation for 7 to 14 days and CDT, therefore, can give an indication of alcohol consumption over this period of time, which gives it an advantage over blood or urine alcohol measurements which only remain elevated for 24-48 hours after alcohol consumption.

How can I lower my CDT level?

People who do not drink, or drink moderately, will have lower CDT levels in their blood. But people who drink four or more drinks a day, at least five days a week for 2 weeks prior to the test will have CDT at significantly greater levels.

What is a low CDT level?

The relationship between CDT levels and alcohol consumption

Among nondrinkers, CDT values ranged from 0.2% to 1.6%. For drinkers, the lowest CDT value was 0.5% (with a daily alcohol intake of 5 g) and the highest was 6.3% (with a daily alcohol consumption of 240 g).

What is a normal CDT result?

The normal value of the serum CDT concentration is under 60 mg/liter; a value between 60 and 100 mg/liter indicates probable alcoholism, and a value > 100 mg/liter indicates a very high probability of alcoholism (specificity: 99%).

Does Iron lower CDT levels?

In conclusion, CDT serum levels are markedly affected by the patient's iron status, with iron overload reducing its sensitivity in alcohol abusers and iron deficiency its specificity in nonabusers. CDT can be considered a reliable marker of alcohol abuse only when iron stores are normal.

How long after drinking do liver enzymes return to normal?

Severe drinking may require three months to a year to fully regenerate the liver to its original capacity and functionality.

What is a high CDT level?

Under normal conditions, only about 1 to 2% of transferrin is carbohydrate-deficient. As a result of heavy drinking, it can go as high as 10%. Studies have found that a %CDT of 2.6% and higher is indicative of heavy drinking. About 50 to 70% of heavy drinkers will have a %CDT greater than 2.6%.

What is abnormal CDT?

Patients with chronic alcoholism may develop abnormally glycosylated transferrin isoforms (ie, carbohydrate deficient transferring: CDT >0.12). CDT results from 0.11 to 0.12 are considered indeterminate. Patients with liver disease due to genetic or nongenetic causes may also have abnormal results.

Will one drink ruin my gains?

Not likely, unless you really hit the bottle. “If your energy intake (the amount you drink) is greater than your energy expenditure, then the increased daily intake will induce weight gain,” says Parr. In other words: If “one” beer is what we're talking about, you're fine.
