Blood coagulants are the core components in blood collection vessels that accelerate blood coagulation, and their performance directly affects the efficiency of serum separation and the accuracy of subsequent testing. Evaluating the suitability of a coagulant should not only focus on its coagulation speed, but also comprehensively consider five aspects: coagulation time, coagulation efficiency, coagulation effect, separation effect, and its impact on blood components. These five dimensions are interrelated and together determine the actual use value of the product. Coagulation time and efficiency The coagulation time refers to the time required for blood to completely coagulate after coming into contact with a coagulant, which is the most intuitive performance indicator. The shorter the time, the faster the coagulation process starts, and the shorter the sample processing cycle. For emergency testing scenarios that require rapid reporting, differences in coagulation time can directly affect work efficiency. The coagulation efficiency focuses on the relative amount of coagulant required to achieve the optimal coagulation effect. Efficient coagulants can achieve ideal solidification speed with minimal addition. This not only reduces the cost of raw materials, but also minimizes the interference of foreign components on blood samples. The coagulation time and efficiency need to be considered in combination: some products require a large amount of addition to achieve rapid coagulation, while others can achieve the same effect with a small amount of addition, and the comprehensive advantages of the latter are more obvious. Condensation effect and separation effect The coagulation effect mainly tests the amount of serum leakage after blood coagulation. After complete coagulation of blood, a blood clot will form, and when the clot contracts, it will squeeze out the serum. A coagulant with good coagulation effect can cause blood clots to fully contract, resulting in a large and rapid amount of serum leakage, thereby increasing the serum yield per unit volume of blood. If the coagulation effect is poor, the serum will be wrapped in loose blood clots and cannot be effectively separated, resulting in sample waste. The separation effect is a comprehensive reflection of the performance of coagulants. After coagulation, the blood needs to be centrifuged to achieve complete serum separation and clear interface. The ideal separation effect is a clear and transparent serum layer, a dense and intact blood clot layer, a clear boundary between the two, and no hemolysis phenomenon. Hemolysis refers to the rupture of red blood cells leading to the release of hemoglobin into the serum, which can cause the serum to appear red and interfere with the detection of multiple biochemical indicators. When evaluating the separation effect, it is necessary to carefully observe whether the serum color is normal and whether the interface is smooth. The impact on essential components of blood This is the most easily overlooked but equally important evaluation dimension. The use of coagulants should not have harmful effects on the clinical test results of blood and the performance quality of blood products. This means that coagulants and their products after reacting with blood should not interfere with the accuracy of subsequent testing results. For example, certain coagulants may affect electrolyte determination, enzyme activity testing, or hormone immunoassay. When evaluating a coagulant, it is necessary to confirm that its interference level with common clinical testing items is within an acceptable range. For scenarios used in the production of blood products, it is also necessary to investigate whether residual coagulants affect the quality and safety of the products. Hubei Xindesheng Material Technology Co., Ltd. specializes in the production of blood collection tube additives such as coagulants.

Heparin sodium, as a commonly used blood anticoagulant, plays an important role in clinical blood collection and in vitro diagnosis. However, the correct usage directly affects the effectiveness of anticoagulation. From the selection of raw materials to the preparation method, and then to the control of dosage, there are details that need to be paid attention to at every stage. Understanding these key points can help users obtain more reliable anticoagulant results. Raw material selection: the difference between crude and purified products There are significant differences between crude and purified products in the raw material sources of heparin sodium. Crude products contain a lot of impurities and complex components, which are not suitable for direct use in situations where they come into contact with blood. We need to use refined heparin sodium, which appears as a white powder. This purified product has higher purity and lower impurity content, which can ensure the stability of anticoagulant effect and reduce interference with blood samples. In actual procurement and use, a clear distinction should be made between crude and refined products, and crude products that have not been refined should not be used directly. Preparation and use: flexible application in solution form The purified heparin sodium is a powdered solid that needs to be dissolved in water to prepare a solvent before use. It is recommended to use appropriate solvent water quality during preparation to ensure complete dissolution before proceeding to the next step. The prepared heparin sodium solution can be directly sprayed onto the inner wall surface of the blood collection tube. The advantage of this usage method is that heparin sodium can be evenly distributed on the inner side of the tube wall. When blood enters the blood collection tube, it immediately comes into full contact with the anticoagulant, achieving a rapid and uniform anticoagulant effect. After spraying, it is necessary to dry it appropriately to avoid diluting the blood sample with excess liquid. Usage control: More is not better There is a standard reference for the dosage of heparin sodium: 20 international units of heparin sodium should be used for every 1 milliliter of blood. This ratio is a relatively optimized dosage that has been verified through long-term practice. It is worth noting that excessive use of heparin sodium does not achieve better anticoagulant effects, but may instead lead to a decrease in anticoagulant efficacy. The reason behind this phenomenon is that excessive sodium heparin can alter the ion environment of the system or cause unexpected interactions with certain blood components, thereby interfering with the normal anticoagulant process. Therefore, when using heparin sodium, following the recommended dosage range is more important than blindly adding dosage. For special samples or specific blood collection vessel specifications, appropriate adjustments can be made based on the reference standard dosage, but deviations should not be too large. comprehensive consideration In addition to the three core points mentioned above, the use of heparin sodium also needs to consider compatibility with other blood collection tube additives. If the blood collection tube contains other functional components at the same time, it is necessary to confirm whether there is mutual interference between them. The storage conditions are also worth paying attention to. Heparin sodium should be stored in a suitable environment to avoid moisture or high temperature that may cause a decrease in activity. In short, although heparin sodium is a mature anticoagulant, it can only exert its anticoagulant effect when the raw materials are selected correctly, formulated correctly, and the dosage is precise. Every detail must be done properly to ensure the quality control of the entire process from blood sample collection to testing.

Lipoprotein (a) is an independent risk factor for cardiovascular and cerebrovascular diseases, diabetes, end-stage renal disease and other major diseases. Its serum concentration is stable, with few interfering factors, and it is an ideal clinical biomarker. With the aggravation of aging in China and the rising incidence rate of cardiovascular and cerebrovascular diseases, the demand for lipoprotein (a) testing continues to grow. The reagent kit based on latex enhanced immunoturbidimetry can be adapted to fully automatic biochemical analyzers, with fast detection, high sensitivity, and controllable cost, and has become mainstream. A certain reagent kit has achieved high linearity, high precision, and strong anti-interference ability through chemical cross-linking and anti-interference formula, with broad market prospects. Among them, HEPES buffer plays an irreplaceable key role as the core basic raw material. 1, The role, dosage, and synergistic significance of HEPES in reagent kits 1.1 Basic functions and dosage of HEPES buffer In the lipoprotein (a) detection kit, Hubei Xindesheng can provide key biological buffering agents such as HEPES, MES, phosphate buffer solution, etc., which run through the entire system of reagent R1, R2 and calibration standards, with large dosage and critical support function. HEPES serves as the core main buffer and is used in both R1 and R2 systems. The concentration of HEPES in R1 is 0.5-10g/L (preferably 1-5g/L), and in R2 it is 0.5-10g/L. The pH is controlled between 5.5-8.5 (preferably 7.0-7.8). With its high buffer capacity and low metal chelation properties, HEPES provides a stable and mild reaction environment for antigen antibody specific binding, avoiding pH drift and ion interference. 1.2 Synergistic effects with other components HEPES highly synergizes with the components within the system: it maintains ionic strength with sodium chloride, reduces non-specific adsorption with Tween-20, protects antibody activity with BSA, assists PEG-6000 in promoting immune complex aggregation, complements EDTA to remove metal ion interference, and provides a stable pH basis for aspartame to exert anti rheumatoid factor effects. 2, The technical parameter requirements of HEPES and the production advantages of Hubei Xindesheng The requirements for HEPES and other biological buffering agents in vitro diagnostic reagents include: purity ≥ 99.0%, 260nm/280nm UV absorbance ≤ 0.05, heavy metal ions
