What is the difference between JH needle and TL needle

26G and 28G refer to the outer diameter of blood collection needle. The larger the number in front of G, the thinner the needle, and the smaller the injury to the wound, the smaller the amount of bleeding, and the better the wound healing. Therefore, for blood glucose meters with relatively small blood volume, 28G or even 30G or even finer needles are generally used, so that the wound and pain are smaller for patients, and the customer experience will be better
