Evacuated Heparin Blood Collection Tubes For Chemistry Plasma Determinations

Heparin Blood Collection Tubes Evacuated Tube System For Chemistry Testing Plasma Determinations In Chemistry

1. Product Introducation:

The evacuated tube system for blood collection in use for various laboratory tests consists of tubes of various sizes, with color coded tops indicating tube contents.

Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant).

Heparin Tube Usage:

Applying to clinical biochemistry, blood specimen collection for emergency biochemical tests and anticoagulation(blood rheology measurement, biochemical test, genetic diagnosis, enzymology, enzyme immunoassay, etc.)

Heparin tubes are coated with spray-dried lithium heparin or sodium heparin, They are used for collecting blood specimen for biochemistry tests and some test items in blood rheology. The anticoagulants heparin activates anti-thrombins, thus blocking the coagulation cascade of the blood specimen producing a whole blood/ plasma sample instead of clotted blood plus serum

This less commonly used bottle is for biochemistry tests which require heparinised plasma or whole blood for analysis.

• Additive: Heparin (Sodium/Lithium/Ammonium)
• What additive does: Inhibits thrombin formation to prevent clotting
• Laboratory uses: Chemistry Testing (Plasma determinations in chemistry) : ammonia, carboxyhemoglobin & STAT electrolytes, chromosome screening, insulin, renin and aldosterone

2. Q&A

Q. What is the source of the heparin that is used in the CIPING Vacutainer blood collection tubes?

A. The heparin is derived from porcine intestinal mucosa.

Q. What types of heparin are offered in the CIPING Vacutainer Blood Collection Tubes?

A. The green top heparin tubes contain either the lithium or sodium salt of the heparin anticoagulant. Lithium heparin should not be used for lithium determinations.

Q. How is the heparin applied to the tube wall?

A. All of the heparin is spray-dried on the wall of the tube.
