Differential Leucocyte Count (DC)

DIFFERENTIAL LEUCOCYTE COUNT (DC) Test

The Differential Leucocyte Count (DC) test measures the percentage and, in some cases, the absolute number of different types of white blood cells (WBCs) in the blood. These cells play an important role in protecting the body against infections and other diseases.

The test typically evaluates neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Changes in their levels can provide useful information about bacterial or viral infections, allergic reactions, inflammation, parasitic infections, and certain immune or blood-related disorders.

A DC is commonly performed as part of a Complete Blood Count (CBC) or may be ordered separately depending on the patient's symptoms and clinical requirements.

DIFFERENTIAL LEUCOCYTE COUNT (DC) Test is Recommended for Individuals:

• Individuals with fever, recurrent infections, or unexplained weakness
• People experiencing symptoms of infection or inflammation
• Individuals with suspected bacterial or viral infections
• People with allergy symptoms or suspected parasitic infections
• Individuals with unexplained changes in their total WBC count
• People undergoing evaluation for immune system or blood disorders
• Patients whose healthcare provider wants to monitor their response to treatment

FAQs

1. What does a Differential Leucocyte Count test measure?
A DC test measures the different types of white blood cells in the blood, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. It helps assess immune activity and may provide clues about infections and other conditions.

2. What can an abnormal DC result indicate?
An abnormal result may occur due to infections, inflammation, allergies, parasitic infections, certain medications, immune conditions, or blood disorders. The significance depends on which type of white blood cell is affected and the overall clinical picture.

3. Is Differential Leucocyte Count included in a CBC test?
Yes. A differential white blood cell count is commonly included as part of a CBC with differential. However, the exact tests included can vary between laboratories, so it is useful to check the test package or laboratory report.
