With the recent Chinese New Year coming, the prices of pigs, cattle and sheep are also rising. Our heparin products are mainly extracted from small intestine and other tissues of pigs, cattle, sheep and other animals. The price of heparin itself is high, so the price of heparin is conceivable when the price of raw materials rises. Therefore, when we use heparin, we must learn more about the influence of different environments on it, which is beneficial for us to save both cost and time.
1. Can heparin sodium anticoagulant tube be placed directly after blood collection?
Answer: No, in order to ensure adequate blood anticoagulation, the heparin salt test tube must be mixed upside down 5-8 times as soon as possible after blood collection. Especially when the ambient temperature of blood collection is higher than 25℃, blood and heparin lithium must be timely and fully mixed, otherwise it is easy to lead to blood coagulation or local coagulation.
2. How long will the test be completed after the anticoagulation of heparin lithium?
A: Heparin sodium anticoagulant is irreversible anticoagulant. The test should be completed within 6 hours after blood is collected with heparin lithium anticoagulant test tube, otherwise the test result may be wrong.
3. What is the appropriate amount of heparin in the heparin tube?
A: Heparin may be involved in the metabolism of enzymes and ions in cells, so the amount of heparin used may affect the results. The dose of heparin should be sufficient to ensure that all and local samples are anticoagulant enough to ensure that most plasma indicators, especially sensitive indicators such as AST, ALT, TBIL, DBIL and GGT, are reproducible within 6 hours.
4. Can heparin be used with separation glue at the same time?
A: Heparin lithium can be used in conjunction with the separation gel. Anticoagulation effect, silicification of tube wall, centrifugation conditions and gel quality all affect blood separation effect. It is suggested that high quality plasma samples can be obtained by combining the blood separation gel produced by our company.
5. What factors affect the titer of heparin?
A: The concentration of sodium chloride has an effect on the titer of heparin sodium. The amount of hydrogen peroxide has influence on the titer of heparin sodium. The oxidation time affected the titer of heparin sodium.
6. Why do some heparin lithium tubes have tiny clotting fragments after blood collection?
Answer: This is because the local concentration of anticoagulant in the heparin lithium anticoagulant tube is too high, leading to partial blood cannot fully mix with the heparin lithium after entering the collection vessel, resulting in some tiny clots. This may be due to the failure to reverse the mixing tube in time after blood collection.
7. What are the storage conditions of heparin lithium?
A: This product can be sealed and stored in a cool and dry place, away from light and moisture. The product can be stored in aqueous solution under the sterile condition of 0-4℃, the maximum storage time should not exceed 7 days. It is recommended that the product can be used in aqueous solution, not stored in solution for a long time. When heparin lithium has impurities, odor, color and abnormal validity period, it is prohibited to use.
8. Is turbidity of heparin solution acceptable?
Answer: When the heparin lithium solution is cloudy, it may be that the heparin lithium solution is contaminated or deteriorated. Please do not continue to use it.
