What Is A CBC Blood Test, And When Should You Take It? 

Managing your health can be a difficult task if you don’t know what issues you have going on in your body. Even a seemingly healthy person can have underlying problems they don’t know about unless they run the proper tests. Sometimes our doctors may ask for tests, but it is also a good idea to learn what symptoms may be a sign of something wrong and that it may be a good idea to have tests run to catch any underlying issues. A CBC blood test is one type of specialized test that is used to do just that. It can detect problems that may otherwise go undetected or that are mistaken for less serious issues.

If you’re unfamiliar with a CBC blood test, that’s ok. In this post, we are going to discuss what this particular test is, what it checks for, and when to know whether you should take one.

What is a CBC blood test, and what does it tell you?

A CBC test is also known as a complete blood count or full blood count test, and it measures a number of factors that have to do with your blood. Most people think of blood as a single component of the body, but multiple components within the blood can determine a variety of health factors. This means that a CBC test is important for your overall health and for detecting conditions that may otherwise go unnoticed.

The first component that the CBC test checks are the red blood cell count. Red blood cells are the most numerous cells in the blood and are responsible for one of the most important jobs in the body. Red blood cells transport oxygen to all the other cells in the body. Without oxygen, these cells would die off and cease to function. In other words, they control our other cells’ ability to live and perform the tasks they are meant to do.

Among other things, a low red cell count can cause fatigue, dizziness, and heart palpitations. One of the most common conditions that can result in a low blood cell count or poor oxygenation of the cells is iron deficiency anemia.

The CBC test also measures your white blood cell count, which is responsible for the health of your immune response and your overall ability to fight off infections and disease. If this count is low, it can be a sign of infection or autoimmune deficiency. Patients who have undergone treatment for cancer or are on specific medications may also have a low white blood cell count,

The next component the test checks is the platelet count found in the blood. Platelets are responsible for the body’s wound recovery response. When a person is injured, platelets are what help cells rebuild and recover. Unlike other issues, the low platelet count can be caused by issues such as pregnancy and medication use, which may not be related to an underlying medical issue.

Lastly, a CBC test checks the concentration of hemoglobin and hematocrit in your blood. These substances are responsible for the transport of oxygen, clotting, and other factors essential to normal blood function.

When should you get this test?

You should get this test if ordered by a doctor or if you notice symptoms of a particular issue such as iron deficiency anemia. It is easier to treat with options such as IV iron infusions if you notice this issue. Compared to taking supplements, IV infusions are a faster and more effective method to replace minerals and nutrients your body is missing and recover from deficiencies.
