What is this test?
- This laboratory test is performed to measure the levels of monocytes in the blood. Monocytes are a type of white blood cells that play a key role in building immunity. Monocytes also kill cancer cells.
Why is this test performed?
- Absolute monocyte count is performed:
- To manage the abnormal levels of monocytes
- To evaluate and manage health conditions such as blood disorders and certain cancers
- To determine the complications after a heart attack
- To diagnose an underlying chronic infection or an autoimmune disease.
- What are monocytes?
Monocytes are the largest type of white blood cells. They play a very important role in building immunity and gives rise to dendritic cells and macrophages.
- What is monocytosis and monocytopenia?
Monocytosis is an abnormal increase in the concentration of monocytes while monocytopenia is an abnormal decrease in the concentration of monocytes. Monocytes are a type of white blood cells that play an important part in the immune system. Monocytes give rise to macrophages and dendritic cells.
- How to prepare for this test?
No special preparations are required for this test. Inform your doctor about the use of all prescribed and non-prescribed medicines. Wear a short-sleeved shirt to aid the collection of sample.
- What are the risks of this test?
Collecting blood from a vein is a very easy procedure and pose only minimum risk, including:
- Bruising
- Bleeding
- Infection
- Lightheadedness.
5. Can monocytes increase in stress?
An increase in monocytes is mostly due to infections but increased stress may also result in monocytosis.
Normal range: Normal range of absolute monocytes is 0.3 to 0.9 x 109/L (2-8% of WBCs).

- Autoimmune diseases
- Leukemia or other type of cancers.
Causes of Increased Absolute monocyte count:
- Chemotherapy
- Radiotherapy
- HIV
- AIDS
- Infections.
