Normal Reference Ranges
Solid Phase
- • 30 min: Rapid if < 70% remaining
- • 60 min: Rapid if < 30%, Delayed if > 90%
- • 120 min: Normal if < 50%
- • 180 min: Normal if < 21%
- • 240 min: Normal if < 10%
Liquid Phase
- • 30 min: Normal if < 50% remaining
- • Liquid typically empties faster than solids
- • Most liquid should empty within 60-90 minutes
