- Time 30: Draw serum cortisol
- Time 60: Draw serum cortisol & give 100mg hydrodortison IVP
^0.125mg if <2yrs old
- Normal Response: Cortisol level doubles from baseline after Cosyntropin administration
- Adrenal Insufficiency: Cortisol level fails to rise after Cosyntropin administration
Treatment
