[Product Name] Lithium heparin blood collection additives
[Package Specification] Plastic bottle, 10g/bottle, 20g/bottle, 50g/bottle
[Performance] White amorphous powder, odorless, soluble in water, easy to absorb moisture, average molecular weight of 15,000, stable at room temperature. The potency of lithium heparin of the company is â?¥150IU/mg, and the potency of anhydrous litnium heparin is â?¥ 160IU/ mg. Other indexes were controlled according to the standard of heparin sodium.
[Scope of application]
1. This product is applicable to the collection and anti-coagulation of blood samples for clinical biochemical examination and emergency biochemical examination, as well as the collection and anti-coagulation of blood samples for some hemorheology projects.
2. It is recommended to use lithium heparin as anticoagulant in clinical test to determine the ions 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 animals.
[Precautions]
In order to ensure adequate anti-coagulation of blood, the heparin salt must be mixed upside down for 5-8 times as soon as possible after blood collection. Especially when the temperature of blood collection environment is higher than 25â??, the mixing of blood and lithium heparin must be timely and sufficient, otherwise it is easy to lead to blood coagulation or local coagulation.
Heparin anti-coagulation is not irreversible, so the test should be completed within 6 hours after blood collection in lithium heparin anti-coagulation test tube, otherwise the test results may be wrong.
Biological buffer
Title: tris (hydroxymethyl) aminomethane Tris
English name Trometamol
Chinese name Tris-(Â hydroxymethyl)-aminometh
[Product Name] Dipotassium EDTA 2K
[Package Specification] Plastic bottle, 500g/bottle
[Performance] White crystal powder, odorless, soluble in water, easy to absorb moisture, molecular weight of 404.6, pH value of 4.8Ã?±1 (5% aqueous solution, g/ml), solubility in water â?Â¥ 60% (g/ml, 25â??). Stable at room temperature. The main content of EDTA in our company is â?Â¥ 99.0%. See the product test report for other indicators.Ã? Ã?Â
[Scope of application]EDTA salt can protect the cellular components of the blood, does not affect the white blood cell count and size, has the least effect on the morphology of the red blood cell , and can inhibit the aggregation of platelets, which is suitable for general hematological test. Except for the isolation and examination of platelets, it is not suitable for coagulation test and platelet kinetic energy test, nor for the determination of calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase and leucine amino peptidase and PCR test.
International Committee for hematology Standardization (ICSH) recommended dipotassium EDTA as anticoagulant for blood cell count and classification. Compared with tripotassium EDTA, it has lower solubility and slower anticoagulation speed.
