1) I hope you haven't done an RTPCR test during the repeat as the RTPCR test may show positive value upto 3months due to viral shedding
2) if you have done an ANTIGEN test during the repeat and it turned positive again then you can repeat the antigen test after 48 hrs.
Next Steps
DONT DO AN RTPCR TEST FOR FOLLOWUP WITHIN 3 MONTHS OF INFECTION AS IT MAY REMAIN POSITIVE
Health Tips
if you have completed 17 days from the onset of symptoms and you are asymptomatic now then there is no need of a repeat test again
