Tubercle Bacillus Syringe

Tubercle bacillus syringe is a precision device used for administering purified protein derivative (PPD) during tuberculosis (TB) skin testing. Healthcare professionals rely on it to perform the Mantoux test, which involves injecting a small amount of solution just beneath the skin, usually on the forearm.

This syringe typically holds up to 1 mL and includes a fine, short needle—often 26 or 27 gauge. The narrow barrel allows for exact dosing, making it ideal for intradermal injections. Clear, easy-to-read markings on the barrel help ensure accurate measurement and better visibility during use.

Greetmed design the syringe for single use, ensuring sterility and safety. Most models come with a pre-attached needle to reduce handling and improve workflow. The sharp, thin needle causes minimal discomfort while delivering the solution smoothly into the dermis.

Because the test involves a very small volume—usually 0.1 mL—precision is essential. The syringe’s design supports careful control, which helps reduce errors and ensures a reliable outcome. After injection, the skin is monitored over 48 to 72 hours for signs of immune response. A raised area or bump may indicate exposure to tuberculosis.

Moreover, the syringe plays a key role in public health and clinical diagnostics. Medical staff often use it in occupational screenings and TB control programs. Its compact size and simple operation make it practical for both mobile clinics and hospital settings.

In addition to accuracy, the tubercle bacillus syringe offers convenience and reliability. Its components are made from medical-grade plastic and stainless steel, ensuring durability and hygiene. With its specialized features, the syringe remains an essential tool in tuberculosis screening and prevention.
