generally i will take 48 - 72 hours for the new drug to act on the pathogen if the pathogen is sensitive to this. so ideally you should wait for another 24-48 hrs by then the throat culture
would be available to you and if needed the antibiotics may be changed depending on sensitivity.
your blood work report points to some infection may be viral or bacterial. both of these can give rise to such kind of report.
is low and it suggests some infection, lymphocyte count
is also low as it should be at least 1500, this also suggests some bacterial infection, though neutrophils are not raised.
low platelet count
(normal range - 1.5 lacs to 2.5 lacs) also is suggestive of some infectious process going on (may be viral or bacterial).
however the reports should be interpreted only with the clinical picture
hope you benefit from my answer
