Sometimes we will find there are too many kinds of blood collection tubes, do you know how to distinguish the vacuum blood collection?  Let's talk more about it. 

Plain tube

Function: No additive. This tube is used for blood specimen collection and storage for biochemistry, immunology, element trace, various types of virus detection and so on for clinical test. Plain tube shall be put in 37°C water for 1 hour after blood collection. Light yellow serum shall be visible before centrifuge.

Pro-coagulation tube

Function: Clot activator is precisely dispensed in the tube. This tube is used for blood collection and storage for biochemistry, immunology, element trace, various types of virus detection and so on for clinical tests. Invert 5-6 times after blood collection, and wait for 30 minutes before centrifuge.

Gel + Clot activator

Function: The tube is dispensed with separating gel and clot activator. This tube is used for blood collection and storage for biochemistry, immunology, element trace, various types of virus detection and so on for clinical tests. Invert 5-6 times after blood collection, and wait for 30 minutes before centrifuge. Centrifuge shall be set as 1500-1700 RCF for 10 minutes.

EDTA tube

Function: K2EDTA or K3EDTA is dispensed in the tube for blood routine tests. The rubber is qualified to match all analyzer probes. Invert 8-10 times after blood collection. And the tube shall be inverted several times before experiment.

ESR tube

Function: Sodium citrate 3.8% is dispensed for sedimentation test. Blood and liquid additive volume ratio is 4:1. This tube could not be used as the first tube to collect blood. Invert 5-6 times after blood collection. And the tube shall be inverted several times before experiment.

ESR tube for ESR Analyzer

Function: Sodium citrate 3.8% is dispensed for sedimentation test. Blood and liquid additive volume ratio is 4:1. This tube is to match ESR Analyzer. This tube could not be used as the first tube to collect blood. Invert 8-10 times after blood collection. And the tube shall be inverted several times before experiment.

Heparin tube

Function: Lithium heparin or Sodium heparin is dispensed for hemorhelogy or emergency biochemistry. For sodium ion test, please use lithium heparin tube. Invert 8-10 times after blood collection.

PT tube

Function: Sodium citrate 3.2% or 3.8% is dispensed for coagulation test. Blood and liquid additive ratio is 9:1. This tube could not be used as first tube to collection blood. Invert 5-6 times after blood collection.

Glucose tube

Function: Sodium fluoride + K2EDTA, Sodium fluoride + Lithium heparin, and Sodium iodoacetate + K2EDTA are the 3 formulas for glucose tube for blood sugar, glucose tolerance, anti-alkaline hemoglobin test and etc. Invert 8-10 times after blood collection.
