Anonymous users2024-02-07There are many different colored blood collection tubes, and they serve the following purposes:
The red capped tube is called a regular serum tube, and the blood collection tube does not contain any additives, and is used for routine serum biochemistry, blood banking, and serology related tests.
The yellow-headed cap test tube is an inert separating gel procoagulant tube, which is generally used for emergency serum biochemical tests.
The test tube with the orange head cover is a rapid serum tube, the specimen type is serum, and the blood is drawn and placed in a water bath for more than 30min for 37 minutes, centrifuged, and the upper serum is set aside.
The purple tube can be used to check blood routine, blood biochemistry and other items.
The black tube is mostly used for the detection of erythrocyte sedimentation rate.
In addition, there are blood culture test tubes (yellow), sodium citrate anticoagulation tubes (blue), serum tubes with or without blood clotting activator or gel separation, heparin tubes with or without gel (green), EDTA anticoagulant tubes (purple), and blood glucose decomposition inhibitor tubes (gray), which are used for the detection of different items.
The different colors of blood collection tubes have their own examination purposes, and the order of use should be followed to minimize the analysis errors caused by specimen collection. At the same time, according to the items to be tested, the corresponding test tube is selected.

Although it is said that the blood collection tubes of the golden skull should also be mixed, in fact, few people do this in clinical practice.

Anonymous users2024-02-051.Plain Serum Tube Red cap, additive-free, used for routine serum biochemistry, blood banking, and serology-related tests. 2.
The rapid serum tube has an orange-red head cap and a procoagulant in the blood collection tube, which is suitable for emergency serum serial testing. 3.The golden head cap of the inert separating gel coagulation tube is added, and the inert separating gel and coagulant are added to the blood collection tube.
Suitable for emergency serum biochemical testing. 4.The heparin anticoagulant tube is covered with a green cap with heparin added to the blood collection tube.
It is suitable for red blood cell fragility test, blood gas analysis, hematocrit test, erythrocyte sedimentation rate and general energy biochemical determination, and is not suitable for blood coagulation test. 5.The light green head cap of the plasma separation tube, with lithium heparin anticoagulant added to the inert separation hose, is the best choice for electrolyte testing, and can also be used for routine plasma biochemical assays and emergency plasma biochemical tests such as ICU.
Plasma specimens can be loaded directly onto the machine and remain stable for 48 hours in a refrigerated state. Anticoagulant tube purple cap for general hematology tests. 7.
Sodium citrate coagulation test tube light blue head cap, sodium citrate mainly plays an anticoagulant role by chelating with calcium ions in blood samples. Suitable for coagulation experiments. 8.

Yellow eggs are not necessarily more "natural", and white eggs are not bleached. On the contrary, they are born like that, including blue-green eggs. But regardless of the color of the eggshells, they are all the same on the inside. >>>More
Of course, it is not allowed to be mixed together, because the composition of each brand of antifreeze is different, and if it is mixed together, it is not good for the car, and it accelerates the consumption of the car, so it is best not to mix together.
What I found is that the general hair color is dark, such as dark black, and his pupil color is also dark, if the hair color is light, such as coffee, his pupil color is also lighter, hehe, it's genetic.
Although the propagation speed of light in a vacuum is the same, due to the different wavelengths and frequencies of different color light, the refractive index of different colors of light in the medium is different, the refractive index is denoted by n, the speed in the medium is set to v, and the speed in the vacuum is c, n=c v, according to which the speed of different colors of light in different media can be deduced.
There is a reddish-yellow pigment in the leaves, called lutein. Usually, lutein covers a large amount of green chlorophyll, and people naturally can't see it. In the fall, deciduous trees stop growing and need only a small amount of nutrients to survive. >>>More
