Question 1

How is the blood sample taken?

Accepted Answer

To take the blood sample, a tourniquet (elastic) band is placed tightly on the upper arm. The patient is asked to make a fist. This helps in the buildup of blood filling the veins and it becomes easy to collect the blood. The skin is cleaned before inserting the needle in the vein in order to prevent bacteria from entering. The needle is then inserted into the vein in the arm and the blood sample is collected in the vacutainer.
