Multi-Sample Blood Collection Needles (Pen Needles)
View Details
Features
- How it works: Heparin is an anticoagulant that inhibits the clotting cascade by activating antithrombin III.
- Additive filling: The heparin is sprayed on the inner wall of the tube. It will help the blood and heparin to mix thoroughly.
- Operation notice: Invert the tube 6-8 times immediately after blood collection to prevent blood clotting.Recommend centrifugal force: 1300-1800g, 10 minutes.

Application
Used for clinical emergency biochemistry and hemorheology testing.
Lithium heparin can be used for emergency electrolyte testing, providing critical patients with professional and timely test results;
- Emergency biochemistry: Lithium heparin is typically used because lithium does not interfere with most routine tests. Sodium heparin contains sodium, which may interfere with sodium testing, but it is used for specific tests.
- Hemorheology testing: cardiovascular and cerebrovascular diseases, diabetes and its complications, hematological disorders, liver disease, and lung disease, etc.
Why this product is chosen?
When testing electrolyte levels, lithium heparin tubes must be used. Sodium heparin tube is prohibited due to the reason that the anticoagulant in sodium heparin tubes contains a large amount of sodium ions, and using them to test blood samples will result in severely elevated serum sodium levels.Sodium heparin tube is suggested for blood rheology testing.
Frequently Asked Questions (FAQ)
A: Lithium heparin is an anticoagulant that prevents blood clotting by inhibiting thrombin, ensuring the blood sample remain fluid for testing.
A:
- Rapid Anticoagulation: Lithium heparin provides rapid and effective anticoagulation, ensuring the blood sample remains liquid almost immediately after collection.
- Minimal Interference: Lithium heparin generally interferes minimally with most laboratory assays, making it a versatile choice for a wide range of tests.
- Plasma Preparation: Blood collected in lithium heparin tubes yields plasma, which is the liquid portion of blood containing clotting factors.
