What Is The Monocytes Test For?
Monocytes are a type of white blood cell that dispose of foreign particles and bacteria.
They should make up about 5 - 10% of your white blood cells.

Get Tested ›How To Test Monocytes
By buying a laboratory test kit with professional nurse or clinic collection, you can accurately measure Monocytes for total reassurance.
Professional analysis in an accredited laboratory ensures rapid result delivery.
The Vitall Full Blood Count (FBC) nurse or clinic test kit includes a Monocytes test and is available for just £79.00.
Tests which include a Monocytes test:
What if Monocytes Results Are High?
There are many possible causes of a high percentage of monocytes in the blood.
Monocytosis is most commonly linked to chronic inflammatory or infectious conditions.
Associations can include chronic inflammatory disease, parasitic, bacterial, or viral infection, collagen vascular disease, or rheumatoid arthritis.
Further testing is often used to help identify the underlying cause. Unless very elevated, a high monocyte level is not usually treated as an immediate concern. A persistently elevated monocyte count may be reviewed further, including alongside symptoms that can occur with the conditions listed above.
What if Monocytes Results Are Low?
A reduced total white blood cell count can often be linked to a low monocyte level in the blood (monocytopenia).
Many conditions can be associated with a lower total white blood cell count, including infection and bone marrow disorders.
This pattern is commonly reviewed further to clarify the underlying cause. Often, it is not treated as an emergency, but the significance can vary depending on symptoms and whether the low count persists over time.
Who Should Take This Test?
Measure your Monocytes levels and measure your general blood and immune health and ability to fight viral & bacterial infections with a Full Blood Count (FBC) nurse or clinic finger-prick bloodtest kit
You get the convenient testing with the reassurance of professional clinical analysis. Your results are delivered quickly & securely online.
This Full Blood Count (FBC) Test is advised if you:
- want the convenience of home testing without waiting for a GP appointment;
- need a high quality, clinically accredited test done in a professional clinical laboratory.
Is the Monocytes test kit safe to use?
Yes, the Monocytes test kit is safe to use. The finger-prick tool causes minimal discomfort and is designed for easy blood sampling at home. However, those with blood clotting disorders or those on blood thinners should consult a healthcare provider before using the test kit.
What should I do if my test results are negative?
A negative result, indicating your monocyte levels are within the normal range, usually suggests that there are no significant health issues related to monocyte level. However, if you're feeling unwell or if symptoms persist, consult with a healthcare provider, as a normal monocyte count does not rule out other health issues.
What actions should I take if my test results are positive?
A positive result, implying abnormal monocyte levels, should be discussed with a healthcare provider. They can assess the results in the context of your health history and symptoms and can advise further medical testing or treatment if necessary.
How do I interpret my test results?
Your test results will indicate whether your monocyte levels are within a normal range, elevated, or low. Medical professionals at the lab will analyse your tests and a report will be made available, explaining the findings in detail. Any abnormal results should be discussed with your GP who can provide a comprehensive interpretation based on your overall health status and symptoms.
How does the Monocytes test kit work?
The test kit works by analysing a small blood sample, which you collect at home with a simple finger-prick tool provided in the kit. Once collected, the sample is returned in the prepaid envelope to a UKAS accredited lab where the level of monocytes in your blood is assessed.
What symptoms can a Monocytes test help identify?
The Monocytes test itself does not directly identify symptoms but rather provides information about your monocyte levels. Correlating symptoms may include persistent fatigue, recurring infections, wounds healing slowly, unexplained weight loss, and often feeling unwell. If you're experiencing these symptoms, a Monocytes test may help pinpoint potential health issues.
What conditions can a Monocytes test help diagnose?
A Monocytes test can help indicate several health conditions. High levels of monocytes may suggest chronic inflammation, stress response from surgery or trauma, autoimmune disorders, and certain cancers. Conversely, low monocyte levels could indicate an issue with bone marrow function or severe infections.
What is a Monocytes test kit?
A Monocytes test kit is a diagnostic tool used to determine the level of monocytes in your blood. Monocytes are a type of white blood cell that play an essential role in your immune system by combating infections and aiding in tissue repair. This self-test is typically performed using a small sample of blood obtained from a finger-prick.
