| Message: | Lithium heparin has minimal chelating properties, minimal interference to water and relatively low cation concentration, so it is recommended to use anticoagulants for chemical measurements in blood or plasma tests. Lithium heparin basically contains no foreign ions, so it should not be used to test lithium in the blood.
What we must know when using lithium heparin:
1. Heparin anticoagulation is not irreversible anticoagulation, so the test should be completed within 6 hours after blood collection from the lithium heparin anticoagulation test tube, otherwise it may cause errors in the test results.
2. Heparin may participate in the metabolism of cell enzymes and ions, so the amount of heparin used may affect the test results. The added dosage of heparin should ensure the full and partial anticoagulation of the specimen, so as to ensure that most of the plasma indicators can be repeated within 6 hours, especially sensitive indicators such as AST, ALT, TBIL, DBIL, and GGT.
3. Lithium heparin can be used with separation gel at the same time, anticoagulation effect, tube wall siliconization, centrifugal conditions, separation gel quality, etc. will affect the blood separation effect. It is recommended to use with the blood separation gel produced by our company to obtain high-quality plasma samples.
4. Suggestion for irradiation sterilization after adding to blood collection tube: use gamma ray irradiation with a dose of 8-25kGy. The radiation dose can be determined by the initial colony count.
Have you remembered these points? As an established manufacturer of blood test reagents, Desheng has been committed to product quality. Because there is no good product quality, any rhetoric will be exposed, but we at Desheng are not afraid. |
