Could a blood donation two days before a CDT alcohol test elevate CdT levels?

Yes, a blood donation two days before a CDT (carbohydrate-deficient transferrin) alcohol test could potentially elevate CdT levels. This is because blood donation can temporarily affect various blood components and may influence liver function, which in turn can impact CdT production. However, the degree of elevation and its significance can vary based on individual factors and the amount of alcohol consumed prior to the test. It's advisable to consult a healthcare professional for specific concerns regarding blood donation and alcohol testing.
