Hello,
With the question “How many white blood cells are normal? ”, the doctor would like to answer as follows:
The white blood cell count 2.92(L)x10^9/liter is lower than normal but not too low. You need to see a doctor to know the cause of such a decrease in white blood cells. When you go to the hospital for examination, the doctor will do some more tests such as myelogram, bone marrow biopsy to evaluate the possibility of marrow production.
Diet does not help you to increase white blood cells, treatment needs to be according to the diagnosis, but you have not approached the diagnosis. However, because the white blood cell status is a bit low, you are prone to infections, so you need to pay attention to cooked food, drink boiling water, and eat fresh and clean food. You should eat nutritious food to promote general health.
If you still have questions about the white blood cell count, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
