What items cannot heparin lithium blood vessels be used for?

Heparin lithium anticoagulant tubes are a common type of blood collection tube in clinical biochemical testing, whose main function is to prevent blood clotting and maintain the original state of the blood for subsequent testing. However, heparin lithium anticoagulant tubes are not suitable for all experimental items, and in some cases, the use of heparin lithium anticoagulant tubes may also affect the experimental results. Therefore, it is necessary to carefully choose the biochemical items that anticoagulant tubes are suitable for.

The following are some items that cannot be used with heparin lithium anticoagulant tubes, and it is important to pay attention to their use:
1. Coagulation related testing: Its main function is to inhibit blood coagulation. Therefore, when conducting coagulation related tests, such as thrombin time (PT), activated partial coagulation time (APTT), and international standardized ratio (INR), the use of heparin lithium anticoagulant tubes can interfere with the results, leading to higher coagulation time.

2. Platelet function testing: The anticoagulant effect of heparin lithium can also affect the function of platelets, so it is not suitable for platelet function testing items such as platelet aggregation rate measurement. In these projects, it is necessary to evaluate the aggregation ability of platelets, and the presence of heparin lithium can interfere with this process, leading to inaccurate results.

3. Thrombosis related items: Similar to coagulation related tests, heparin lithium anticoagulant tubes are not suitable for thrombosis related items, such as D-dimer assay, fibrinogen assay, etc. These projects usually require accurate evaluation of coagulation and fibrinogen formation in the blood, and the anticoagulant effect of heparin lithium can interfere with the evaluation data.

4. Platelet counting: Platelet counting is usually performed using blood samples collected from EDTA anticoagulant tubes, rather than heparin lithium anticoagulant tubes. The presence of heparin lithium anticoagulant tubes may cause platelet coagulation, thereby affecting the accuracy of platelet counting.

5. Blood culture: When conducting blood culture, it is usually necessary to use blood samples without anticoagulants, so heparin lithium anticoagulant tubes are not suitable for blood culture projects.

Although heparin lithium anticoagulant tubes have a wide range of applications in clinical laboratories, they are not suitable for all experimental projects. When selecting the type of blood collection vessel, the experimenter needs to carefully select according to specific experimental requirements and project characteristics to ensure accurate and reliable detection results. If a blood collection vessel is mistakenly used in a specific project, it may lead to deviation in the results, which may be detrimental to the diagnosis and treatment of patients. Therefore, it is important to understand the applicability of different blood collection vessels and use them correctly as needed.
