Collection Methods of Phlebotomy
 
As I have stated before, there is a method to our madness. People come in all shape and sizes,  and so do their veins. This is why we have different collection methods for different kinds of  veins. There are three collection methods that phlebotomists use when obtaining a blood  sample.
 
The safest method of blood collection is the vacutainer, also known as the vacuum (evacuated)  tube. This method involves a tube, a double-sided needle, and a plastic holder. Blood flows  directly into the tube which limits your contact with the blood. Each tube has a vacuum system  that will allow the blood to stop on its own. All tubes are designed with a “fill line.” This is to  ensure that the blood-to-additive ratio is accurate. Always check to make sure your tube is full  before removing the needle.
