Differential Leucocyte Count (DLC)

Test Overview

Overview of Differential Leucocyte Count (DLC)

The differential leucocyte count (DLC), also called a white blood cell (WBC) differential or leucocyte differential count, is an important blood test that assesses the number and percentage of different types of white blood cells in the blood. White blood cells are essential for the immune system, defending the body against infections, diseases, and foreign substances. The DLC measures the proportions and absolute counts of five key types of white blood cells: neutrophils, lymphocytes, monocytes, eosinophils, and basophils.

Price of the Differential Leucocyte Count (DLC)

The cost of a DLC blood test can vary based on factors such as the location of the diagnostic centre, the type of laboratory, and any additional tests or services provided. On average, the DLC test price ranges between Rs. 100 and Rs. 300. It's important to confirm the exact DLC test price with your chosen diagnostic centre.

Tests Included in Differential Leucocyte Count (DLC)

The DLC count typically includes several tests that provide a comprehensive analysis of the white blood cells. These tests include:

• Neutrophils: These cells primarily combat bacterial infections and acute inflammation by engulfing and destroying foreign particles and microorganisms.
• Eosinophils: Involved in fighting parasitic infections and allergic reactions, eosinophils help reduce inflammation.
• Basophils: Involved in allergic reactions and inflammation, basophils release histamine, causing symptoms like itching and swelling.
• Lymphocytes: Crucial for the adaptive immune response, lymphocytes, including B cells and T cells, help fight viral infections and other pathogens.
• Monocytes: These cells mature into macrophages, which are responsible for cleaning up dead cells and foreign substances.

Optional tests that may be included based on the results of other tests:

• Blasts: Immature cells that are not typically found in the peripheral blood. Their presence can indicate leukaemia or bone marrow disorders.
• Pro-myelocytes, Myelocytes, Meta-myelocytes, and Bands: These cells represent different stages of neutrophil development. Their presence in the blood can indicate infection or bone marrow stress.
• Prolymphocytes: Early stages of lymphocyte development, rarely found in the blood.
• Atypical Cells: Abnormal cells that do not fit into standard categories, possibly indicating infection, inflammation, or malignancy.
• NRBCs (Nucleated Red Blood Cells) per 100 WBC: Indicates the presence of immature red blood cells in the blood, signalling bone marrow stress or disease.
• Corrected TLC: Adjusts the total leucocyte count depending upon the presence of nucleated red blood cells.

What Conditions Can be Diagnosed with the Differential Leucocyte Count?

Some of the most common conditions that can be diagnosed with the DLC test include:

• Allergies: Elevated eosinophil counts can indicate allergic reactions or conditions like asthma.
• Bone Marrow Disorders: The presence of immature cells or abnormal cell counts can suggest bone marrow disorders, such as aplastic anaemia or myelodysplastic syndromes.
• Infections: Bacterial, viral, and parasitic infections can cause changes in the white blood cell counts, particularly neutrophils and lymphocytes.
• Leukaemia: Abnormal or immature white blood cells, such as blasts or atypical cells, can be signs of various types of leukaemia.
• Inflammatory Diseases: Chronic inflammatory conditions, such as rheumatoid arthritis or inflammatory bowel disease, can cause changes in monocyte and lymphocyte counts.

Differential Leucocyte Count Test Requirements

To undergo a DLC blood test , you will need to visit a diagnostic centre or have a phlebotomist collect your blood sample. The requirements for the DLC test are as follows:

• Fasting: Fasting is not typically required for the DLC test, but it may be necessary if other tests are being performed alongside it.
• Sample Collection: A phlebotomist will draw a small blood sample from a vein in your arm using a sterile needle and collect it in a vial. The process is quick and relatively painless. The blood sample will then be sent to the laboratory for processing and analysis.

Note: The values of these tests can vary depending on the laboratory conducting the DLC count , age, sex, and underlying conditions.

Lifestyle Changes for a Normal Range on the Differential Leucocyte Count

If your DLC test shows abnormal results, your doctor may recommend certain lifestyle changes to help improve your immune system and overall health. These changes may include:

• Maintaining a balanced diet rich in fruits, vegetables, whole grains, and lean proteins.
• Staying hydrated by drinking a sufficient amount of water throughout the day.
• Engaging in regular exercise, as recommended by your doctor.
• Managing stress through relaxation techniques, such as meditation or deep breathing exercises.
• Getting enough quality sleep each night to allow your body to repair and regenerate.
• Avoiding smoking and excessive alcohol consumption.
