Journal Article
TL;DR: The Stotz colorimetric procedure does not liberate significant amounts of acetaldehyde if the precipitated blood is promptly distilled because the precipitate is separated before raising the temperature in distillation.
Abstract: The details of the methodology of the study are described, and the results are discussed. The measurement of acetaldehyde in precipitated blood seemed to be complicated by the production of acetaldehyde from a nonethanol source. It was also found that the Stotz colorimetric procedure does not liberate significant amounts of acetaldehyde if the precipitated blood is promptly distilled because the precipitate is separated before raising the temperature in distillation. The findings indicate that further refinement in methods will be required before accurate estimation of the amounts of acetaldehyde produced in blood by ethanol metabolism is possible.

TL;DR: It was found that during the first 70 minutes after drinking, the alcohol level of capillary blood averaged 7.5 % above that of venous blood, and was 15 to 22 % higher in 7 of the 34 pairs of samples, while later samples showed no significant difference between blood from these two sources.
Abstract: Alcohol analyses were conducted with rebreathed air, finger-tip capillary blood, and cubital-vein blood from 31 human subjects, with the three samples taken almost simultaneously 1, 2, and 3 hours after ingestion of whisky. Details of the study are described and the results are discussed. It was found that during the first 70 minutes after drinking, the alcohol level of capillary blood averaged 7.5 % above that of venous blood, and was 15 to 22 % higher in 7 of the 34 pairs of samples. Later samples showed no significant difference between blood from these two sources. It is noted that for estimating blood alcohol level, the rebreathed air method is definitely an improvement over Drunkometer methods. With the rebreathed air procedure, a determination of breath carbon dioxide is unnecessary.
