Diagnosed With Von Willebrand Disease, Had Accident, Consumed Alcohol, Bac Level Test Done. Effect Of Blood Disorder On BAC Level?
Question: I was diagnosed with von willebrand factor. I'm 22 years old, 5ft. 3 , 130 lbs. I recently was in a car accident and unfortunately was taken to hospital where I was given a bac level test ( I had 3 drinks about 4 hours before the accident occurred). I was wondering if my blood disorder could have any adverse affect on my BAC level

Just to give you more details about my condition..My VWF Antigen values taken at 2 different times were 43 and 36, my VWF ristocetin cofactor values were 43 and 46. About a week before the accident, I was given DDAVP intrevenously. After the DDAVP, my factor VIIIc increased from 89 to 196, VWF Antigen to 97 and VWF ristocetin to 117. I am baffled because the blood results from the BAC test just came back from and they are an unusually high level..I had only had 3 drinks more than fours hours before and the results indicated I had consumed about 10 drinks..at those results, I couldn't be conscious. I know the DDAVP leaves the system within 24 hours but could that have affected the levels at all a week later? I am desperate for some answers because I know the test is inaccurate..Are you sure there is no way my condition could affect this test? Thank You
Hi,
Thanks for the follow up query.
Yes, the half-life of DDAVP (Desmopressin Acetate) is only about 2 hours and it is completely cleared from the body in a day. But, theoretically it can have some effect on blood alcohol level.
DDAVP is also known as anti-diuretic hormone, because it decreases water excretion though urine so that the body water content increases. In this situation, if somebody takes a certain amount of alcohol, his/her blood alcohol content will be slightly lower than another person with a standard body water content who has taken the same amount in same time. Thus the BAC (Blood Alcohol Concentration) may become falsely low! But in your case it was falsely high, so I don't think it is because of the DDAVP.
The exact reason is difficult to pinpoint. There are many variables which may affect the test. The nurse drawing the blood should not clean your skin with a alcohol swab prior to drawing the blood. The right color tube must be used and it must be put into the tube correctly. Even then biochemical tests are always subject to machine and human errors.
Still I feel that your condition per se is not responsible for the falsely high level.
Hope I answered all your questions. Please accept my answer in case you do not have further queries. Wish you Good Health.
