Leukocyte 14.5 is a relatively high white blood cell count and is the first item in the blood count. An elevated level indicates an associated inflammatory response in the body and possibly a corresponding infection. It depends on the severity of the disease before deciding whether to give fluids. If it is considered a common cold, then even if it is serious, sometimes the application of relevant oral medications can solve the problem. However, if oral medication is not enough to control the disease, then infusion is recommended. Therefore, the decision of whether or not to administer fluids is mainly based on the other symptoms of the body. If there are symptoms that indicate a more serious condition or if oral medication does not cure the disease, then infusion is recommended. Another indication for infusion is when there are obvious signs of dehydration, such as nausea, vomiting, inability to eat, or obvious diarrhea, and infusion is necessary. Infusion is also recommended if there is a significant bacterial infection and oral antibiotic therapy is not generally expected to be effective.
