What is a blood test?

Blood tests help doctors check a person for certain disease and condition through the examination of their blood. They determine whether the organs in a person’s body are functioning well and healthy.

What can be determined from a blood test?
By recommending blood tests, the doctor can determine the following from the results:

  • Assess how well your blood is clotting
  • Check whether you are at risk for heart disease or other coronary diseases
  • Diagnose health conditions and diseases such as cancer, diabetes, anemia, HIV/AIDS, etc.
  • Evaluate how well major body organs such as the kidneys, liver, heart, thyroids, etc. are working
  • Check whether your medication is working or if there is an improvement in your condition

How are blood tests administered?
Many blood tests don’t require preparation, although some may require you to go on a fast for 8-12 hours before the test so you won’t be allowed to eat before then. During the test, a small amount of blood is drawn from a vein in your arm using a needle or syringe. Sometimes, a finger prick is sufficient. Once the needle is withdrawn, you'll be asked to apply gentle pressure with a piece of gauze, cotton or bandage to the place where blood was drawn. This helps stop bleeding. After a minute or two, you can remove the pressure. The test is usually brief and easy but it may cause a little discomfort, depending on your threshold of pain.

How is the blood tested?
Laboratory workers usually draw the blood and analyse it. They use either whole blood to count blood cells, or they separate the blood cells from the fluid that contains them. This fluid is called plasma or serum. The fluid is used to measure different substances in the blood.

Are there side effects or complications to getting your blood tested?
Blood tests don’t cause serious reactions when it is being done. If there are complications, it is minor and will disappear shortly after having your blood drawn. You might get minor bruising from the needle, but it will also vanish after a while.

What happens next after getting your blood drawn?
Doctors will analyze the results of your blood test then they will discuss the findings with you. The results will detect health problems and conditions in its early stages and will help the doctor determine whether you should be given medication or treatment or a slight lifestyle change will suffice.

What are some tests the doctor may recommend?
The most common tests the doctor may order are full blood count or complete blood count (FBC or CBC), blood chemistry tests, blood enzymes tests, platelets or mean platelets value (MPV), etc.
