A perpendicular intradermal injection is novel technique different from the standard of care Mantoux technique.
- Intradermal injection volumes are small, typically 0.1 - 0.2 mL. Use a 1 ml syringe (or smaller) for maximum control.
- After needle cannula insertion into the skin and during injection: Do not push the Bella-mu needle into the skin.*
- A clearly visible bleb/wheal indicates a successful intradermal injection.
* Pushing (hard) compresses the dermis and hinders the intradermal injection and/or places the formulation too deep. Ease the force or pressure after needle insertion, the colored needle hub should be loosely in contact with the skin, the needle itself must have disappeared fully into the skin.
