Table 2: Results of antemortem laboratory investigations for patients transported to hospital (n = 13/17)*

Investigation	Level, median (range)	Normal range†
Peak potassium, mmol/L	7.0 (4.4–12.5)	3.5–5.1
Peak creatinine, mmol/L	214 (146–1127)	50–110
Peak AST, U/L	2944 (116–5124)	7–40
Peak creatinine kinase, U/L	8200 (1952–237 960)	38–215
Lowest recorded glucose, mmol/L	1.9 (0.4–17.1)	3.9–6.1

Note: AST = aspartate transaminase. *Data missing for 4 patients; they were pronounced dead shortly after arrival to the emergency department (no antemortem investigations). †Normal values were obtained from the Royal College of Physicians and Surgeons of Canada. (17)
