Frequently asked questions
How is the blood sample taken?
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.
What is the function of sodium in the body?

How does our body try to keep the range of sodium very narrow?
Our body tries to keep the range of sodium very narrow by producing hormones that increase or decrease the amount of sodium that is eliminated in the urine. It produces an antidiuretic hormone that is responsible for preventing the loss of water from the body. Our body controls the thirst. When there is an increase in sodium levels, the body feels thirsty. When we drink water, the sodium level comes to normal.
