Question

There are certain tests that require blood, such as tests that determine how healthy the liver is for instance, in which the patient will be advised to abstain from any form of alcohol for at least 24 hours.

Answer 1

Your healthcare provider will tell you when to stop eating and drinking before the test. Food and drink before the test may affect the results. Drinking a lot of alcohol within a day or two of the test can cause abnormal results. It's recommended that you avoid alcohol for about 48 hours before the test.

Answer 2

Much in the same way that an A1C test can detect glucose levels in the blood over a period of 90 days, the CDT test can detect heavy alcohol consumption over a long period of time. If the person stops drinking, the CDT levels will decrease, but if they start drinking again, the levels will once again increase.D
