A Differential Leucocyte Count (DLC) is an important blood test that measures the different types of white blood cells (leucocytes) in the body.
Leucocytes play a key role in defending the body against infections, immune responses, and maintaining overall health. This test provides valuable insights into the body’s immune function and helps diagnose various medical conditions, such as infections, inflammatory diseases, and blood disorders.
The test provides a detailed breakdown of the differential count of leucocytes, which aids in diagnosing various conditions by determining whether the number of a specific type of leucocyte is too high or too low.
1] Neutrophils: Help fight bacterial infections.
2] Lymphocytes: Responsible for producing antibodies and fighting viral infections.
3] Monocytes: Help remove dead or damaged tissue and fight chronic infections.
4] Eosinophils: Active in allergic reactions and fighting parasitic infections.
5] Basophils: Play a role in inflammatory responses and allergic reactions.
A differential leucocyte count measures the levels of the following white blood cells:
1] Neutrophils: Normally, neutrophils make up 40-60% of the total white blood cell count. A high neutrophil count, or neutrophilia, usually indicates a bacterial infection, stress, or inflammation. Low neutrophil counts, or neutropenia, can indicate viral infections or bone marrow suppression.
2] Lymphocytes: These cells account for 20-40% of the white blood cell count. Elevated lymphocyte levels, or lymphocytosis, are typically seen in viral infections, while low levels (lymphopenia) could suggest autoimmune disorders, HIV, or immune suppression.
3] Monocytes: Monocytes make up 2-8% of white blood cells. Elevated monocytes (monocytosis) can indicate chronic infections, inflammatory conditions, or certain blood cancers. Low levels are rare but can occur with bone marrow issues.
4] Eosinophils: Normally, eosinophils comprise 1-4% of white blood cells. Increased eosinophils, or eosinophilia, are commonly associated with allergic reactions, asthma, and parasitic infections.
5] Basophils: The least common white blood cell, basophils make up 0.5-1%. High basophil levels (basophilia) may be seen in certain blood cancers, allergic reactions, or chronic inflammation.
The differential count of leucocytes varies slightly depending on factors like age, gender, and health status. Below are the general normal ranges for different types of white blood cells:
1] Neutrophils: 40%–60%
2] Lymphocytes: 20%–40%
3] Monocytes: 2%–8%
4] Eosinophils: 1%–4%
5] Basophils: 0.5%–1%

Yes, certain medications can affect your white blood cell count. For example, chemotherapy, corticosteroids, and immunosuppressive drugs can reduce white blood cell levels. Make sure to inform your healthcare provider about any medications you are taking before undergoing the test.
The Differential Count for Leucocyte test involves drawing a small sample of blood, usually from a vein in your arm. The blood sample is sent to a laboratory, where the white blood cell types are either manually counted under a microscope or analyzed with an automated machine.
The risks associated with the test are minimal. Some patients may experience mild discomfort or bruising at the site where the blood sample is taken. In rare cases, there may be slight bleeding or infection at the puncture site.
No special preparation is needed for a differential leucocyte count test. However, if the test is part of a broader panel that includes other blood tests, your doctor may ask you to fast for several hours before the test. Always inform your doctor of any medications or supplements you are taking, as some drugs can affect white blood cell levels.
