When we go to the hospital for medical checkups, the blood collection tubes used in blood tests are generally red tube cap blood collection tubes, which are suitable for general blood tests.
Orange Test Tube Cap Blood Collection TubesWhen we go to the hospital emergency, we carry out blood tests, which adds a procoagulant, which helps the hospital some emergency experiments.
Yellow Test Tube Cap Blood Collection TubesWhen we go to the hospital, there are some ingredients added to the blood collection tubes, which are suitable for emergency serum biochemistry testing
Gray Capped TubesWhen we perform blood glucose testing, we use gray capped tubes, which have some anticoagulant sodium fluoride, which has a good preventive effect against degradation of blood glucose, and it is a good preservative of the blood glucose testing.
