Attention should be paid to the use of separation gel blood collection tube

详情

Separation gel blood collection tubes have been widely used in clinical laboratories. The blood collection tubes added with separation gel can form a membrane between cell components and serum, which can effectively prevent the fusion of blood cells and serum, and can maintain serum components for a certain period of time of the stability.



There are two commonly used separation hoses

1. Serum separation gel to promote coagulation tube

The serum separation gel coagulation tube is to add a coagulant to the serum separation gel blood collection tube to shorten the blood coagulation time and quickly obtain the effect of serum. However, there is no need to add a coagulant in the glass blood collection tube, because blood will naturally coagulate when contacting the glass tube wall.

 

2. Plasma separation gel anticoagulation tube

The plasma separator gel anticoagulant tube is sprayed with anticoagulant products such as lithium UFH on the inner wall of the separator gel blood collection tube to meet the needs of rapid plasma biochemical emergency testing.

 

In the clinical application of separation gel blood collection tubes, many irregular operations will affect the separation effect. Some separation gel blood collection tubes interfere with some testing items. These problems are not easy to be found in daily quality control and routine testing. In order to ensure the authenticity and credibility of the test results, it is very important to do a good job of quality control of blood samples before testing.

 

1. In the pre-analysis stage, the laboratory should strictly follow the manufacturer's instruction manual to rationally use the separation gel blood collection tube, and operate in accordance with the correct centrifugal conditions (centrifugation temperature, speed, direction, etc.).

 

2. Minimize the interference caused by the abnormal formation of the separation gel to the test. Attention should also be paid to observe the separation effect of the separation gel after the sample is centrifuged, in order to prevent abnormal samples from being detected on the machine to cause the phenomenon of glue hanging that is not easy to find, which will affect the test results of subsequent samples.

 

3. In the large-scale laboratory's assembly line test platform, all operations such as centrifugation, cap removal, and machine testing of samples are all automated, and more attention should be paid to the separation effect of the samples.
