When do you expect the number of WBCs in a person's blood to be more find the percentage healthy or when he or her are suffering from any infection ?
Answers
Sorry to throw a boulder in the pond here, but as often as the WBC goes up with infection it can also drop, sometimes precipitously…
Viral infections often cause an overall drop in WBC but the lymphocyte count will be elevated a bit.
In overwhelming bacterial infection it is very common for the WBC to drop precipitously. This is mainly due to neutrophils being consumed way faster than the body can produce them. If this situation is prolonged for several days it is not very good prognostically.
Also, many patients who get severe infections are immunocompromised and therefore do not respond appropriately to infection.
And, no, a high WBC, by itself, is nowhere near diagnostic of infection…
ANSWER IS.......
Your body produces more WBCs when you have an infection or allergic reaction. You can also have more WBCs when you are under stress. The normal number of WBCs in the blood is 4,500-10,000 white blood cells per microliter (mcL).
