A purple blood tube, also known as a lavender or EDTA tube, is a type of blood collection tube that contains the anticoagulant ethylenediaminetetraacetic acid (EDTA). EDTA is used to prevent coagulation by binding to calcium ions in the blood, which are essential for coagulation to occur. The primary purpose of collecting blood into a purple tube is to obtain whole blood specimens for laboratory analysis or testing.
The purple tube is typically used for hematology testing, including complete blood counts (CBCs), which are used to evaluate the overall health of a patient’s blood. When a sample of blood is collected into a purple tube, it is mixed well to ensure that the anticoagulant is evenly distributed, thus preventing clots from forming.
Unlike other types of blood tubes, the purple tube can be kept at room temperature for several hours before being centrifuged to separate the plasma or serum. The centrifugation process separates the cellular components of the blood from the plasma or serum, which can then be used for laboratory testing.
In addition to hematology testing, the purple tube can be used for DNA testing, blood typing, and other tests that require whole blood specimens. The use of the purple tube is preferred over other types of blood collection tubes for hematology testing because it provides the most accurate results. Proper handling and transport of the purple tube are critical to maintaining the integrity of the blood sample and obtaining accurate test results.

What is the yellow stuff in blood test tubes?
The yellow substance in blood test tubes is commonly known as a serum separator or serum separator gel. It is a gel that is usually made up of a silicone-based compound, which is inert and non-reactive with the blood components. The role of the serum separator is to separate the blood cells from the serum in a blood sample, which is important in laboratory tests.
When a blood sample is collected, it is usually drawn into a test tube or vial that contains the serum separator gel. After the tube is filled, the blood is allowed to clot, and then the tube is centrifuged. Centrifugation results in the separation of the blood components. The weight of the blood cells and the clot causes them to be at the bottom of the tube, while the serum separator gel sits on top of the blood, forming a physical barrier between the red blood cells and the serum.
The serum is then collected and used for laboratory analysis.
The serum separator gel works by forming a barrier between the blood cells and the serum. It prevents the blood cells from coming into contact with the serum, which can cause hemolysis or the destruction of the red blood cells. Hemolysis can affect the results of the laboratory tests and can lead to inaccurate readings.
The yellow color of the serum separator gel is due to the presence of the silicone-based compound used to make the gel. Silicone is a yellowish translucent substance, which is why the gel has a yellow hue when viewed through the test tube.
