Vial Math and Syringe Units
Vial math gets confusing because labels and syringes often use different measurement systems.
DoseGlass can calculate from user-entered values, but it cannot verify your label, medication, prescription, syringe, or intended amount. Confirm with a qualified clinician or pharmacist.
Common Confusion Points
- Milligrams are not the same as milliliters.
- Syringe units depend on syringe type.
- Changing water volume changes concentration.
- Compounded products can have different instructions.
- Old notes can become dangerous if a vial concentration changes.
How DoseGlass Helps
DoseGlass keeps the values visible: bottle amount, water added, amount you were told to use, syringe type, draw volume, and unit marks. The app keeps the math transparent rather than hiding it.
