How to Use This Calculator

Enter Patient weight (kg), Indication, and PID.
Set ITP, Kawasaki, and GBS/CIDP.
Adjust IgG trough level (mg/dL), Route as needed.
Review the Total dose per cycle (g) result.
Use Dose per day (g) and Volume per day (mL) to inform your decision.

How the result changes with Patient weight (kg)

Patient weight (kg)	Total dose per cycle (g)
