AN OVERVIEW
About TLC and DLC test
Why is the TLC and DLC test done?
The TLC & DLC tests are done:
- As a component of complete blood count (CBC) tests during regular health checkups.
- For examining infections and inflammation.
- To diagnose ailments that lead to lowering of WBCs, such as bone marrow disorders.
- For monitoring the functioning of bone marrow.
- For monitoring chemotherapy treatment.
What does the TLC & DLC test measure?
The total leukocyte count (TLC) provides us the total number of white blood cells (WBCs) present in a given volume of blood.
On the other hand, the percentage of different types of WBCs is measured by the differential leukocyte count (DLC).
Risks/side effects of TLC & DLC test :
No side effects are associated with a TLC and DLC test, although, for a few days, some pain might be felt in the area from where the blood is taken using a needle.

THINGS TO KNOW AFTER GETTING TESTED
Interpreting the TLC and DLC test results
Reference range:
The reference range for the TLC & DLC test is given below:
| Tests | Normal Range |
| TLC At birth 1-3 years 4-7 years 8-12 years Adults | 10,000-25,000/cu mm 6,000-18,000/cu mm 6,000-15,000/cu mm 4,500-13,500/cu mm 4000-10500/cu mm |
| DLC Neutrophils Lymphocytes Eosinophils Monocytes Basophils | 40-80 % 20-40% 1-6 % 2-10 % 0-1 % |
Different factors are responsible for determining the normal range of leukocyte count, including age, gender, health state, history of previous ailments, vaccines, etc. The range also may vary among different laboratories.
WBC count in the blood can be influenced by various ailments, such as immune system disorders, autoimmune conditions, cancer, etc. In some instances, more than one type of the white blood cell may be present in abnormal amounts.
Differential leukocyte count is used for diagnosing different diseases in the body. Further tests might be done to confirm the DLC test results and also to provide therapy.
Leukocytosis refers to an elevation in TLC by more than 10,000/cu mm.
Leucopenia refers to a decrease in TLC by less than 4,000/cu mm.
Leukocytosis can be caused due to:
Inflammatory conditions, including rheumatoid arthritis; allergies; different types of cancer, including leukemia and myeloproliferative neoplasm.
Conditions that lead to necrosis (tissue death), including severe burns, trauma, surgery, etc.
Smoking, doing excessive exercise, pregnancy, intaking drugs like corticosteroids, epinephrine, heparin, lithium, etc.
Leukopenia can be caused due to:
Myelo suppression as a result of poisons, radiation, or chemotherapy.
Bone marrow problems that restrain the production of leukocytes, including myelodysplastic syndrome, deficiency of vitamin B12, etc.
Neutrophil Count:
Decreased levels of neutrophil, commonly known as neutropenia, can occur during aplastic anemia, autoimmune disorders, drug reactions, or chemotherapy.
Increased levels of neutrophil, commonly known as neutrophilia, can occur during acute bacterial infections, inflammation, and burns.
Lymphocyte Count:
Decreased levels of lymphocytes, commonly known as lymphopenia, can occur during bone marrow damage, aplastic anemia, autoimmune disorders.
Increased levels of lymphocytosis, commonly known as lymphopenia, can occur during acute viral infections, tuberculosis, lymphocytic leukemia.
Monocyte Count:
Decreased levels of monocytes are rare to be found.
Increased levels of monocytes, commonly known as monocytosis, can occur during chronic infections like tuberculosis, bacterial endocarditis, collagen vascular disorders, and inflammatory bowel diseases.
Eosinophil Count:
Decreased levels of eosinophil are rare to be found.
Increased levels of eosinophil, commonly known as eosinophilia, can occur during asthma, allergies, drug reactions, and parasitic infections.
Basophil Count:
Decreased levels of basophil are rare to be found.
Increased levels of basophil, commonly known as basophilia, can occur during chronic myeloid leukemia (CML).
TLC and DLC Test in Chandigarh
Starts from 50*
TLC stands for total leukocyte count & DLC stands for differential leukocyte count. Tests are available for the same.
Leukocytes are also called white blood cells (WBCs) and help our immune system in fighting several diseases. These are of five types: neutrophils, basophils, eosinophils, monocytes, and lymphocytes. A chronic ailment which may require urgent attention can be signified by an endless rise in the levels of WBCs.
