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..
What is abnormal CDT?
Interpretation. 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.
How long should you abstain from alcohol before a CDT test?
The duration of abstinence before blood testing can cause differences in study results, especially for CDT, which has a relatively short half-life of 15 days (Behrens et al., 1988; Stibler et al., 1988). Nevertheless, the time since the last drink is included in only a few studies.
How can I lower my CDT levels?
In most people, an elevated CDT will return to normal during several weeks of alcohol abstinence. It will also decrease if a person substantially reduces drinking. CDT is specific for heavy alcohol use; 30% reduction in CDT is consistent with a substantial reduction in alcohol intake.
What are the first signs of liver damage from alcohol?
Generally, symptoms of alcoholic liver disease include abdominal pain and tenderness, dry mouth and increased thirst, fatigue, jaundice (which is yellowing of the skin), loss of appetite, and nausea. Your skin may look abnormally dark or light. Your feet or hands may look red.
How much do alcoholics drink a day?
The top 10 percent of American drinkers – 24 million adults over age 18 – consume, on average, 74 alcoholic drinks per week. That works out to a little more than four-and-a-half 750 ml bottles of Jack Daniels, 18 bottles of wine, or three 24-can cases of beer. In one week. Or, if you prefer, 10 drinks per day.
What is a high CDT reading?
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%.
Does drinking water flush alcohol out of your system?
Water can help reduce your BAC, though it will still take one hour to metabolize 20 mg/dL of alcohol. Avoid caffeine. It’s a myth that that coffee, energy drinks, or any similar beverages alleviate intoxication quicker.
Can a blood test show heavy drinking?
Blood tests are one of the most reliable methods for detecting heavy alcohol consumption. They can also effectively measure blood alcohol level (BAC).
What liver tests show alcohol damage?
Diagnosis typically relies on laboratory tests of three liver enzymes: gamma–glutamyltransferase (GGT), aspartate aminotransferase (AST), and alanine aminotransferase (ALT).
Does smoking affect CDT test?
Our results show that mean CDT increases with increasing reported alcohol consumption even within the range of alcohol use considered to be nonhazardous. We found significant effects of sex, age, smoking, previous alcohol dependence, body mass index, and diastolic hypertension on the alcohol-CDT dose-response curve.
How much drinking makes you an alcoholic?
Key Chain Blood-Alcohol Testing May Make Quantified Drinking Easy. Women who consume eight or more drinks per week are considered excessive drinkers. And for men, excess is defined as 15 or more drinks a week. (The researchers defined a drink as just 5 ounces of wine, 12 ounces of beer or 1.5 ounces of spirits.)
What lab values indicate alcoholism?
Specific markers for chronic alcohol use are carbohydrate-deficient transferrin (CDT) and phosphatidylethanol (PEth). Nonspecific markers include gamma-glutamyl transferase (GGT), mean corpuscular volume (MCV), aspartate aminotransferase (AST), and alanine aminotransferase (ALT).
What is a normal CDT result?
In heterozygous, or carriers of the disease, CDT levels are variable but typically are in the range 10-25%. 3) Level of alcohol consumption necessary and over what period to increase the CDT level to 3.0%. Typically the level of alcohol intake required to produce a CDT result of 3.0% is 100-150 g alcohol/day.
Does water lower CDT levels?
A single episode of heavy drinking will not elevate CDT levels. CDT is reported as a percentage of total transferrin to reduce the effects of gender and varying transferrin concentrations. Note: 95% of non-drinkers and individuals with normal drinking patternss, have a %CDT of < 1.8%.
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 does it take to get your CDT back to normal?
The half-life of CDT is usually 14–17 days; values return to normal 3 or 4 weeks after abstinence. Women may have a higher CDT than men.
How do I get my CDT levels back to normal?
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 …
