This method of calculation seemed reliable as long as the same approach was used which required the consumption of alcohol all at one time on an empty stomach. During the course of his research Widmark discovered what has been labeled as Widmark's r factor. Widmark's r factor was the product of a test subject's calibration curve.

Blood alcohol content can be estimated by a method developed by Swedish professor Erik Widmark [] in the 1920s: = / (×) − × where: A is the mass of alcohol consumed.; r is the ratio of body water to total weight. It varies between individuals but averages about 0.68 for men and 0.55 for women, since women tend to a higher percentage of fat.

A reagent of potassium dichromate-sulfuric acid mixture was found potent within 3 weeks after preparation when kept air-tight in hard glass ware without exposure to light, and 0.01 N sodium thiosulphate reagent was potent within 2 weeks under similar conditions. Widmark's uncertainty method yielded 1.6 drinks (CV=15.4%). The derivation of Widmark's uncertainty estimate is also presented, showing that he considered only rho and beta to be uncertain. Widmark estimates for the number of drinks should include a 2CV estimate of approximately 25% while the blood alcohol concentration estimate should include a 2CV estimate of approximately 42%.

Abstract : This thesis investigates whether a qualitative research method, using phenomenological interviews and analysis, can be successfully applied to

Widmark's r factor was the product of a test subject's calibration curve. Die Widmark-Methode erfasst jedoch alle verdampfbaren und oxidierbaren Substanzen, ist somit ethanolunspezifisch. Sie gilt heute als obsolet und ist seit dem Jahr 2007 mit der „Richtlinie zur Bestimmung der Blutalkoholkonzentration im Blut (BAK) für forensische Zwecke – BAK Richtlinie“ zur forensischen Blutalkoholbestimmung nicht mehr zugelassen.

The derivation of Widmark's uncertainty estimate is also presented, showing that he considered only rho and beta to be uncertain. Widmark estimates for the number of drinks should include a 2CV estimate of approximately 25% while the blood alcohol concentration estimate should include The Widmark modeling approach is a best practices method for superimposing multiple alcohol doses ingested at various times with alcohol elimination rate adjustments based on individual body factors. The elimination rate from blood was lower in those subjects with larger distribution volume. The results show that blood-ethanol parameters calculated according to Widmark's method have low inter subject variability when the dose of ethanol administered and the condition of the test subjects are carefully controlled.) eters calculated by the pharmacokinetic modeling method and on the basis of the Widmark equation.

Widmark Factor can be estimated for any subject. Zuba and Piekoszewsk2 commented that the Widmark procedure was the most popular method of making alcohol calculations. In 1981, Watson et al.3 suggested an alternative formulation, changing the terminology to bring greater clarity and make the dilution equation easier to understand.
