3.-Diagnostic-criteria-for-rhabdomyolysis:-•-dark-urine-
OR-
• an-acute-neuromuscular-illness-without-other-symptoms-
PLUS-
• an-acute-elevation-in-serum-CK-(at-least-5x-the-upper-limit-of-
normal)-
4.-CK-in-rhabdomyolysis:-•-most-reliable-test-for-dx-
rhabdomyolysis-
• will-be-marketing-elevated,-typically->-1000-
• Begins-to-rise-within-2-12-hours-and-continues-to-rise-until-
peaks-around-24-72-hours-following-onset-of-injury-

•half-life-1.5-days,-and-level-declines-within-3-5-days-of-muscle-
injury-cessation-•-CK->-5000-often-results-in-AKI-
5.-Serum-myoglobin-in-rhabdomyolysis:-•-Released-from-
cells-immediately-when-skeletal-muscle-is-injured-and-rises-
rapidly-in-serum-
• Excreted-rapidly-so-levels-may-return-to-normal-within-6-8-
hours-of-injury-(half-life-2-3-hrs)-
• Normal-serum-myoglobin-does-not-exclude-rhabdomyolysis-
as-dx-and-is-less-reliable-biomarker-than-elevated-CK.-
6. Normal-CK-range:-45-260-IU/L-
7. Normal-myoglobin-level:-25-72-mg/mL-(varies-per-
laboratory)-

10. Urine-myoglobin-on-dipstick:-Detectable-as-"blood"-with-
concentrations-as-low-as-0.5-mg/dL,-even-long-after-urine-
has-returned-to-its-usual-color-
Therefore,-urine-color-does-not-exclude-rhabdomyolysis-as-a-dx-

muscle-injury-
Significant-transaminitis-may-also-be-present-with-
rhabdomyolysis-
12. Electrolyte-imbalances-commonly-seen-with-
rhabdomyolysis:-•-hyperkalemia-
