What is the function of red blood cells?

Answered by Apollo Doctors

My 8 month old niece has had a persistent fever for the past 2 weeks. It normalizes when given antipyretics but recurs every 8 to 10 hours. She has a normal diet but sometimes skips meals. She has also vomited 2 to 3 times. A blood test report showed a high lymphocyte count of 58. She traveled about 400 km last week, although comfortably. Could this affect her condition? What could be the reason, and what do you suggest? Thank you in advance.

My blood report shows mild leukocytosis, and my lymphocyte count is increasing each month. Currently, my lymphocyte count is 5.67. Is there anything to worry about?
