What is
separation glue?
It forms an
isolation layer between cell components and serum (plasma),
effectively preventing the exchange of substances between blood
cells and serum (plasma), and ensuring the stability of serum
(plasma) components within a certain period of time. It is a
high-molecular polymer substance, insoluble in water, inert, and a
viscous liquid with thixotropy. The density is between 1.***1.*5
mmol/L. It has oxidation resistance, high temperature resistance,
low temperature resistance, and air tightness. Good to wait for the
advantages. The serum density is 1.****1.**1 mmol/L, and the blood
cell density is 1.****1.**5. Due to the specific gravity, the
separation gel is just between the serum and blood cells, so under
normal circumstances, blood serum, separation gel, and blood cells
will appear in sequence after centrifugation. 3 floors.

Reasons
for poor separation effect of separation gel
1.
Separation glue quality
The specific
gravity of the separation gel is between serum (plasma) and blood
cells, which is the physical basis for the reversibility of the
separation gel and the separation of serum (plasma). If the quality
of the separation gel for blood collection tubes is poor and the
specific gravity cannot meet the requirements, it will inevitably
affect the separation of serum (plasma), and the separation gel and
serum (plasma) are likely to be intertwined.
Â
2.
Incomplete blood clotting
After
centrifugation, sometimes the separation of the separation gel
compartment from the serum and blood clots is incomplete, and there
are phenomena such as fibrin filaments in the serum. The reason is
often that the blood did not completely coagulate before
centrifugation.
Â
3.
Centrifugation temperature
The centrifugation
temperature has a significant effect on the separation of serum by
the gel coagulation tube. In the inert separation gel accelerator
tube separated by ordinary centrifuge at room temperature, the
serum is clear, but oily beads of different sizes appear in *5% to
*0% of the samples. However, no oily beads were found in the serum
separated from the test tube centrifuged in a low-temperature
centrifuge. When the temperature exceeds the storage temperature
required by the separation hose, the inert separation gel will
dissolve in the serum. It will not only block and contaminate the
sample needle and reaction cup of the biochemical analyzer, but
also have a relatively large impact on the results of some
biochemical assays.
Â
4.
Centrifugal operation
Centrifugation is
an important part of the preparation of high-quality serum samples
with the separation gel coagulation tube. Generally, the blood
collection tube separation gel requires that the blood is collected
by **0° and gently inverted and mixed for 8 to *0 times, and placed
upright for *0 minutes after the sample is fully coagulated.
Centrifuge for *0 minutes in a centrifuge, and maintain the
centrifugal force at ***0～***0×g, so that the serum
(plasma) and the blood clot are completely separated by the
separating gel. If the centrifugal force is too low, the force
acting on the separation gel will be weak, and the separation gel
will have poor reversibility. Fibrin condensate may stay in the
serum or colloid layer, which can easily block the sample needle of
the automatic analyzer. On the contrary, if the centrifugation time
is too long, it is difficult to form a network structure after the
hydrogen bond is cut in the separation colloidal aggregate, and the
thixotropy is lost.
Â
5.
Serum/plasma density
The density of
serum (plasma) is the main reason that affects the floating of the
separating gel, not its viscosity. Any factor that causes the
density of serum (plasma) to increase and exceeds the density of
the separation gel can cause abnormal reversion of the separation
gel.
