My mother 66years old was just discharged from hospital after recovering from a UTI
kidney infection. Post that she was told to continue antibiotics Intravenous(Ertapenem Eczas) once a day for one week and follow up with the doctor with fresh CBC,
CRP, KFT and USG KUB.
My question is how soon after completing the antibiotics course should she take a blood test for a clear/accurate result? After 24 hours or can we wait and take the blood tests 2-3 days later?
