What Is a TLC Blood Test and Why Is It Done?

A TLC (Total Leukocyte Count) blood test measures the number of white blood cells in your blood, which play an important role in protecting the body against infections. Doctors may recommend this test to investigate persistent fever, weakness, suspected infections or certain immune system disorders. A high TLC count may indicate infection or inflammation, while a low count can occur due to certain medical conditions, medications or bone marrow problems. TLC results are usually interpreted alongside other blood tests and symptoms.
