With the development of technology, the application of biochemical testing technology in clinical practice is extremely common, providing strong support for clinical medical diagnosis. In routine blood testing, in order to improve detection efficiency or ensure accuracy, additives are often needed for auxiliary experiments. For example, the application of serum separation gel can quickly separate, or heparin lithium can play an anticoagulant role, blocking blood coagulation and prolonging blood sample coagulation time. Is it possible to use heparin lithium anticoagulant so that medical staff can conduct the experiment immediately after blood collection? Do you need to leave it for a period of time? Below is a specific introduction for everyone. Due to the fact that heparin can control thrombin from the source, causing thrombin to lose activity and preventing platelet aggregation, it can to some extent hinder blood clotting. It is precisely because of this performance that the vast majority of blood collection experiments will use it, but there are also some issues to pay attention to when using it: 1. Lithium heparin contains almost no foreign ions, so it is not commonly used to detect lithium in the blood. 2. The vacuum test tube contains lithium heparin, which needs to be placed for a certain period of time after collecting the blood sample. The main purpose is to make the blood sample fully contact with lithium heparin and have an anticoagulant effect. During the placement process, the operator is required to slowly invert and mix 5-8 times. 3. The placement time after blood collection should be within 6 hours, and it is best to complete the test within this time, otherwise it may lead to errors in the test results. 4. The placement time after blood collection should pay attention to the interference of environmental temperature, especially when the blood collection environment conditions are above 25 degrees, the placement time should be shortened as much as possible, otherwise local coagulation will affect the detection process. 5. Pay attention to the amount of lithium heparin added, and ensure that the blood sample is fully anticoagulated to ensure that the blood does not change within 6 hours. 6. Heparin lithium can usually be used in combination with serum separation gel. Within a certain period of time, it is not only necessary to pay attention to the anticoagulant effect of heparin lithium, but also to the separation effect of serum separation gel. After complete separation and standing for a period of time, it can be tested and analyzed on the machine. From the above six aspects, it can be seen that the heparin lithium tube needs to be left for a period of time after blood collection, but it should not exceed 24 hours, and the test should be completed as soon as possible. As a professional manufacturer of heparin lithium, Desheng not only has rich experience, but also pays close attention to quality. All key indicators of its products must meet the standards before they can be sold before leaving the factory. If you have any
