In the United States, healthcare professionals must be familiar with the appropriate test tubes to use for different types of blood collection procedures. This article will discuss the different types of test tubes used in medical labs and phlebotomy settings in the United States.
Serum Tubes
Serum tubes are used to collect blood samples for tests that require serum, such as chemistry panels and certain hormone tests. These tubes are typically made of glass or plastic and do not contain any additives. The most common color for serum tubes is red, but they can also be gold or tiger-topped (red with a black or gold ring). These tubes are designed to allow the blood to clot and separate from the serum, which is then tested in the laboratory.
Types of Serum Tubes:
Plasma Tubes
Plasma tubes are used to collect blood samples for tests that require plasma, such as glucose tests and coagulation studies. These tubes contain an anticoagulant, such as Heparin or EDTA, to prevent the blood from clotting. The most common color for plasma tubes is lavender (EDTA), but they can also be green (Heparin) or light blue (Sodium Citrate). These tubes are designed to keep the blood in a liquid state so that the plasma can be separated and tested in the laboratory.
Types of Plasma Tubes:
- Lavender Top tubes (EDTA)
- Green top tubes (Heparin)
- Light Blue Top tubes (Sodium Citrate)
Whole Blood Tubes
Whole blood tubes are used to collect blood samples for tests that require whole blood, such as blood typing and hemoglobin tests. These tubes contain additives that prevent the blood from clotting and preserve the integrity of the sample. The most common color for whole blood tubes is blue, but they can also be gray or black. These tubes are designed to keep the blood in a liquid state so that the entire sample can be tested in the laboratory.
Types of Whole Blood Tubes:
- Blue top tubes
