Answer:

There are different types of blood collection tubes used for various purposes in medical laboratories. Each type of tube contains specific additives to aid in the proper analysis of blood samples.

1) Lavender tube with K2EDTA:

The lavender tube with K2EDTA is commonly used for whole blood hematology testing. The K2EDTA additive acts as an anticoagulant, preventing the blood from clotting and preserving the integrity of the blood cells for accurate hematological analysis.

2) Gray tube with sodium fluoride and potassium oxalate:

The gray tube with sodium fluoride and potassium oxalate is used for glucose testing. The sodium fluoride acts as a glycolysis inhibitor, while potassium oxalate acts as an anticoagulant. This combination helps in preserving the glucose levels in the blood sample for accurate testing.

3) Serum tube with clot activator and gel:

Serum tubes with clot activator and gel are used to obtain serum, which is the plasma component of the blood without the coagulation factors. These tubes are essential for separating the serum from the blood cells, allowing for further analysis and testing in medical laboratories.
