total leucocyte count (TLC) normal range
What is TLC
TLC stands for total leucocyte count. It is a blood test that measures the number of white blood cells (WBCs) in a sample of blood. WBCs are an important part of the immune system and help to fight infection.
What is the normal TLC range
The normal TLC range varies depending on age and sex. In general, the normal TLC range for adults is 4,000 to 11,000 WBCs per microliter of blood. For children, the normal TLC range is slightly higher.
What does a high TLC mean
A high TLC can be a sign of infection, inflammation, or other medical conditions. Some common causes of a high TLC include
* Infections, such as pneumonia, meningitis, and sepsis
* Inflammation, such as rheumatoid arthritis and lupus
* Bone marrow disorders, such as leukemia and lymphoma
* Medications, such as steroids and chemotherapy
What does a low TLC mean
A low TLC can be a sign of bone marrow suppression, which is a condition that occurs when the bone marrow does not produce enough WBCs. Some common causes of a low TLC include
* Bone marrow disorders, such as aplastic anemia and myelodysplastic syndrome
* Cancer chemotherapy
* Radiation therapy
* Infections with certain viruses, such as HIV and hepatitis C
* Medications, such as those used to treat autoimmune diseases
What should I do if my TLC is abnormal
If your TLC is abnormal, your doctor will likely order additional tests to determine the cause. These tests may include a complete blood count (CBC), a blood smear, and a bone marrow biopsy.
