Indicators for determining inflammatory cells in blood tests look at the normal values of leukocytes and neutrophils. The normal range of white blood cell count is (4.0-10.0)×10^9/L and the percentage of neutrophils 0.51-0.75. An increase in both or one of them at the same time indicates the presence of inflammatory infection, bleeding, poisoning, leukemia, etc. in the body. The presence of inflammatory cells in the body can be inferred from routine blood tests, but it cannot confirm the diagnosis and cannot be used as a basis for bacterial infection. It is necessary to find the specific bacterial infection to confirm the diagnosis according to the condition, combined with body fluid, secretion culture and blood culture. Inflammatory infections may be accompanied by fever, redness, swelling and pain symptoms.
