The kit includes a 3ml syringe pre-filled with 25IU of dry Lithium Heparin, which is used to prevent blood clotting during the sampling process. Additionally, the kit also comes with a 5ml waste syringe for safely disposing of any excess or used samples. To maintain the integrity of the collected samples, an ice bag is also included in the kit. This kit is designed for single-use to ensure sterility and prevent cross-contamination. It comes in a case of 200, making it a convenient choice for busy medical facilities.
