Yes, white blood cell (WBC) counts are usually higher in tuberculosis (TB) patients than in healthy individuals. This is because the body's immune system is fighting the infection, and WBCs are a crucial part of this defense.
Here's why:
- WBCs fight infection: White blood cells are the body's primary defense against infections, including TB. They attack and destroy bacteria and other pathogens.
- Increased WBC production: In response to TB infection, the body increases production of WBCs, particularly lymphocytes, to combat the Mycobacterium tuberculosis bacteria.
- Elevated WBC count: This increased production leads to a higher overall WBC count in TB patients.
However, it's important to note that a high WBC count alone doesn't confirm a TB diagnosis. Other factors like symptoms, chest X-ray results, and specific tests for TB are crucial for diagnosis.
