Heparin lithium is a chemical with a white to nearly white appearance. There was no significant difference in TP, Aso, UA, alt, Mg, Cl, TC and CRP between heparin lithium anticoagulant plasma and serum (P > 0.05). There were significant differences in HBD, LDH and TBA between heparin lithium anticoagulant plasma and serum (P < 0.05). Therefore, except for HBD, LDH and TBA, the correlation between heparin lithium anticoagulant plasma and serum is good. Therefore, it is feasible to use heparin lithium anticoagulant plasma instead of serum in life detection, which can be used as an important detection method.
Basic information of Desheng product heparin lithium

[scope of application]
1. This product is suitable for the collection and anticoagulation of blood samples for clinical biochemical examination and emergency biochemical examination, as well as for blood sample collection and anticoagulation of some Hemorheology items.
2. It is recommended to use heparin lithium as anticoagulant when determining the ion content in blood, because it is the least likely to interfere with the determination of other ions.
3. This product is not a drug and cannot be used as an injection. It is forbidden to inject directly into human body and animal body.
In order to ensure sufficient blood anticoagulation, heparin salt test tube blood collection must be reversed and mixed 5-8 times as soon as possible. Especially when the ambient temperature of blood sampling is higher than 25 ℃, the mixing of blood and heparin lithium must be timely and sufficient, otherwise it is easy to cause blood coagulation or local coagulation.
Heparin anticoagulation is not irreversible anticoagulant, so the test should be completed within 6 hours after blood collection of heparin lithium anticoagulant test tube, otherwise, the test results may have errors.
Heparin may be involved in the metabolism of cell enzymes and ions, so the amount of heparin used may affect the detection results. The dosage of heparin should ensure full and local anticoagulation, so as to ensure that most of the plasma indexes can be repeated within 6 hours, especially ast, alt, TBIL, DBIL, GGT and other sensitive indicators.
Heparin lithium can be used with separation gel at the same time, anticoagulant effect, tube wall silicification, centrifugal conditions, separation gel quality and so on will affect the blood separation effect. It is suggested that high quality plasma samples can be obtained by using the blood separation gel produced by our company.
It is suggested to use gamma ray irradiation with a dose of 8-25kgy. The irradiation dose can be determined by the initial colony number.
[warning and prevention]
It is forbidden to use heparin lithium in case of impurities, abnormal smell, color and expiration date.
Do not use the heparin solution when it is contaminated with lithium bacteria.
This product is a biological preparation, safe, non-toxic and harmless.
