Have you been to any health care to get your blood taken? Have you ever wondered what a common blood test detects? If so, then this article is perfect for you. It contains everything you need to know about the blood test. Basically, blood tests are a procedure that doctors used to check about what is going on inside your body. It is a test done to check for any illnesses. Besides, it is also used to observe the drug level in the body and monitor the drug’s action. If there is any issue regarding your result, doctors then will know what to do. They will base their treatment on the blood test result that has been taken.

             A blood test is usually done in a hospital or any healthcare setting. The one responsible for taking your blood will be either your doctor or a healthcare worker. Usually, you will be asked to fast if required. If not, then you can drink some water before the procedure begins. This is to make sure that your body stays hydrated. It will be harder for the doctors to find your vein, if you are dehydrated.

             During a blood test, a strap is wrapped tightly around your arm. This is to make sure your vein is visible so that it is easier to draw blood. Then, a needle will be inserted into your vein, and blood will be drawn until it is enough. People with difficulty getting their blood taken from the arm might use a different device called the ‘butterfly’. This needle will be inserted at the back of your hand instead of your arm in order to conduct the same process.

             Your blood is filled into a container and will be sent to a chemical lab for testing. How fast you will get your result will depend on the type of blood test that you took. There are some common blood tests that you need to know. These include:

  1.   Complete Blood Count (CBC)

In this test, your doctor will check a variety of blood components such as the number of red blood cells, white blood cells, hemoglobin, platelets, mean corpuscular volume (average size of your red blood cells) and hematocrit (how much space your red blood cells take up in the blood). Basically, a CBC test will help the doctor to check for any blood component-related diseases such as infection, inflammation, anemia, blood clotting issue or any problem with your immune system. Your doctor might order you to fast before taking this test.

  1.   Blood enzymes test

As the name suggests, this blood test will check for your enzyme level in the body. Our body produces enzymes that are crucial in making sure that our body system works perfectly. If the level is too high or too low, a further action will be taken by your doctor. You might need to undergo some other tests or might even start on an immediate treatment.

  1.   Blood clotting test

This test is also known as the coagulation panel. It checks for any protein that is responsible for making a blood clot. Any issue with these proteins will give a blood clotting disorder.

  1.   Lipoprotein panel

This test aims to check your cholesterol level. This includes low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol and triglyceride. Usually, it is used to check for any cholesterol-related disease such as cardiovascular disease.

  1.   Basic metabolic panel (BMP)

It measures different chemicals that are found in your blood such as electrolytes, calcium level, glucose level and also kidney’s chemicals. It is very useful in detecting any issue with the bones, muscles and organs.


             All of these tests are a typical routine check for a doctor. They will run this test first in order to detect the problem involved. After that, they will decide what is the next step needed. These can be a further test or an immediate treatment.
