We examined the effects of time, temperature, and a preservative (sodium fluoride) on ethanol concentrations in stored samples of whole blood from living human subjects. We measured the ethanol in the first, second, seventh, and 14th day of storage, by gas chromatography. Samples were stored at 0-3 degrees C and at 22-29 degrees C, with and without preservative. None of these showed significant...
