- Fixed Mass Dose
- Convert target mcg to mg, divide by concentration (mg/mL) to get volume
- Protocols where all subjects receive identical absolute dose regardless of body weight
- ±0.01mL with insulin syringe (±2.5mcg at 2.5mg/mL)
- Simplest calculation but doesn't account for subject size variation. Use only in homogenous study populations
- Body Weight Ratio
- Multiply subject weight (kg) by mcg/kg protocol dose, divide result by concentration
- Research mimicking published clinical trials or comparing results across species
- ±5% when subject weight measured to 0.1kg precision
- Industry standard for dose normalisation. Required for cross-study comparison and regulatory submission
- Concentration-Matched Volume
- Select desired injection volume first, calculate required concentration, reconstitute to that concentration
- Long-term studies where measurement consistency across timepoints is critical
- Eliminates volume measurement variability. Same syringe graduation used throughout
- Best for minimising operator error in multi-week protocols but requires precise reconstitution volume control
