2. Figure 1
Percent distribution of ALT values (in IU/L) on presentation and upon repeat testing within the following 24 hours. Of the 40 patients, only those with minimally disturbed LFTs (n = 18) had repeat testing within 24 hours.

3. Figure 2
The temporal relationship between onset of upper abdominal pain and LFTs (n = 40) for (A) alkaline phosphatase, (B) ALT, and (C) total bilirubin (n = 32).

5. Figure 4
Repeat LFTs in patients with normal or minimally disturbed values on presentation (n = 18). The figure depicts the rise in LFTs represented as the average fold-increase for each specific test between the initial blood draw in the Emergency Department and the repeat blood draw within 24 hours (*P < .05; **P < .01).

(A) Boyle's law regulating pressure-volume relationship of a fluid in a closed cylinder. The pressure created in the cylinder equals the force applied divided by the area of the piston (P = F/A) and (B) pressure dynamic model of a stone obstructing the biliary outflow at the sphincter choledochus, resulting in retrograde high amplitude phasic contractions.
