TLC & DLC Test: Complete Guide, Procedure, and Interpretation at Sanovra Lab
Blood tests are one of the most common and essential diagnostic tools used by doctors to assess a person’s overall health. Among these, TLC & DLC tests are crucial in evaluating the immune system and detecting infections, inflammation, and blood disorders.
At Sanovra Lab, we provide accurate and reliable testing services to help you and your doctor make informed health decisions.
What is TLC & DLC?
TLC (Total Leukocyte Count): TLC measures the total number of white blood cells (WBCs) in your blood. White blood cells are vital for fighting infections and protecting the body against diseases.
DLC (Differential Leukocyte Count): DLC breaks down the total white blood cells into different types, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. This helps identify specific conditions like bacterial infections, viral infections, allergies, and more.
Importance of TLC & DLC Test
The TLC & DLC test is recommended for:
- Detecting infections: High or low WBC levels can indicate bacterial, viral, or parasitic infections.
- Monitoring immune health: Assessing the body’s ability to fight diseases.
- Diagnosing blood disorders: Conditions like leukemia or anemia.
- Evaluating inflammation or allergies: DLC can reveal high eosinophils, suggesting allergies.
- Tracking treatment progress: After medications, especially chemotherapy or antibiotics.
By testing both TLC and DLC, doctors get a detailed view of your immune system’s functioning.
Procedure for TLC & DLC Test
- Sample Collection: A small blood sample is drawn from a vein in your arm using a sterile needle.
- Lab Analysis:
- TLC: The total number of white blood cells per cubic millimeter of blood is counted.
- DLC: The types of white blood cells are identified and expressed as a percentage of the total WBC count.
- Result Interpretation: Results are usually available within a few hours to a day.
Normal Ranges of TLC & DLC
TLC (Total WBC Count):
- Adults: 4,000 – 11,000 cells/µL
- Children: 5,000 – 13,000 cells/µL
DLC (Differential WBC Count):
| Type | Normal Range (%) |
|---|---|
| Neutrophils | 40 – 60 |
| Lymphocytes | 20 – 40 |
| Monocytes | 2 – 8 |
| Eosinophils | 1 – 4 |
| Basophils | 0.5 – 1 |
Factors Affecting TLC & DLC
- Infections: Viral or bacterial infections can increase or decrease WBC count.
- Medications: Steroids, chemotherapy, and antibiotics may influence counts.
- Stress or Exercise: Physical or emotional stress can cause temporary changes.
- Medical Conditions: Autoimmune diseases, bone marrow disorders, and allergies.
Interpreting Abnormal Results
- High TLC (Leukocytosis): May indicate bacterial infection, inflammation, stress, or leukemia.
- Low TLC (Leukopenia): Can result from viral infections, chemotherapy, or bone marrow issues.
- Abnormal DLC:
- High neutrophils → bacterial infection
- High lymphocytes → viral infection
- High eosinophils → allergies or parasitic infection
- High basophils → chronic inflammation or allergies
