Question
My friend has had a fever for over 12 hours and went to the hospital today for a blood routine check. They feel a bit uneasy and want to know if it’s necessary to have a blood routine test after a fever of 12 hours?
Answer
Generally speaking, it is meaningful to undergo a blood routine test after having a fever for over 12 hours. If the blood routine test results are normal, it should be highly suspected that there is a possibility of viral infection. It is recommended to adopt antiviral treatment and conduct a mycoplasma antibody test to exclude the possibility of mycoplasma infection. At the same time, it is suggested to go to the hospital for a series of rheumatoid tests, including anti-chain O and erythrocyte sedimentation rate tests, to make an accurate diagnosis and use appropriate medication for targeted treatment. For children, it is generally recommended to use venous blood for the blood routine test to ensure accuracy.
