Taking Levofloxacin Tablets will not affect the nucleic acid test. Levofloxacin tablets are quinolone antibacterial drugs, which have therapeutic efficacy against bacteria, mycoplasma, chlamydia, anaerobic bacteria and other pathogens, and are ineffective against viruses. New coronavirus nucleic acid test is mainly through the nasal swab or pharyngeal swab to take specimens to PCR detection, the technology is highly sensitive, as long as the nasal mucosa or pharyngeal mucosa detected in the viral genetic material can be shown as positive. New coronavirus is a virus, levofloxacin tablets have no therapeutic and inhibitory effect on the virus, so taking levofloxacin tablets will not affect the number of viruses, and will have no effect on the results of the nucleic acid test of new coronavirus.
