Products Description

ESR Vacuum Blood Collection Tube ESR vacuum blood collection tube is mainly used to collect venous blood to test the erythrocyte sedimentation rate. The following is a detailed introduction:

Structure and material

It is generally composed of a tube body and a head cover, and the tube body is mostly made of PET plastic or glass. PET material blood vessel is light, not easy to break, transport and use more convenient; The glass material has high transparency and strong chemical stability, which is more conducive to observing blood samples and ensuring the accuracy of detection.

• The lid is usually black in color to distinguish it from other types of sampling vessels.

Additive and principle

• The tube is pre-loaded with 3.2% to 3.8% sodium citrate solution as an anticoagulant, with a ratio of 1:4 to the blood.

• The principle is to prevent blood clotting by combining sodium citrate with calcium ions in the blood, so that the blood remains liquid, in order to accurately measure the sedimentation rate of red blood cells over a certain period of time.

Specification and capacity

• The common specifications and sizes are 13×75mm, 13×100mm, 16×100mm, etc., and the corresponding nominal capacity is generally 2ml, 3ml, etc.

Scope of application

• Mainly used to detect erythrocyte sedimentation rate, a non-specific inflammatory indicator, which is often used to assist the diagnosis and monitoring of a variety of inflammatory diseases, such as infections, autoimmune diseases, some cancers, etc., and can also be used for disease assessment and monitoring of treatment effects.
