What are Monocytes (Absolute & Percent), Normal/Optimal Ranges + Meaning?

What are Monocytes?

We are constantly surrounded by germs in our environment that can have a negative effect on our body and health. In severe cases, they can harm us and even cost us our lives. When these germs enter our bodies, our immune system views them as invaders that must be fought off. Our immune system has a key component called the white blood cells, of which there are several different kinds.

Monocytes are a type of white blood cell that fights off bacteria, viruses and fungi. They are the biggest type of WBC in the immune system. Originally formed in the bone marrow, they are released into our blood and tissues. When certain germs enter the body, they quickly rush to the site for attack. Monocytes are very flexible cells in that they can change depending on cues they receive from the environment. For example, they can develop into macrophages, which are cells that eat bacteria, viruses, parasites, cells that have become infected, and debris in tissues.

The optimal reference range for Monocytes is between 0.2 and 0.9 K/MCL.
