How do blood tests work?

A blood draw is known by some people as venipuncture and the medical personnel who perform blood drawn are called phlebotomists. Before your blood is taken, these phlebotomists will do the following:

  • They will wash their hands with hand sanitizer, soap or water before wearing gloves.
  • A tourniquet in the form of an elastic rubber band will be placed on your arm.
  • They will look for a vein and when they find one will clean the location with an alcohol wipe.
  • A tiny hollow needle will certainly be inserted into the blood vessel. Blood will leave your vein through the needle to a syringe or collection tube.
  • The tourniquet will be removed and they will apply gentle pressure on the area the blood was taken. A bandage might be placed on it in some cases. 

Blood draw does not take time if your veins are easily seen and accessed. It takes five to ten minutes to do this. When the vein is not easily noticed, It will take more time. Other factors that can make the blood draw to take time include:

  • Dehydration 
  • Size of the vein 
  • The experience level of the phlebotomists. 

Some blood tests and their duration

    Your doctor usually receives the result of such laboratory tests within a day.
  • Basic metabolic panel
