Regarding covid treatment. In this!

Hi. I with family have to travel to kolkata due to job transfer. In this regard as per air travel guidelines I with my family done a RT-PCR test on 26th March 2021 before my scheduled travel. But among us my spouse's report has become positive on 27th March 2021 and we cancelled our travel for this. I immediately isolate her another room and consult a doctor for covid treatment. Doctor suggest me to do CBC, BSR, CRP, S.cretinine, IL6 etc for both of us. But when I send the the to Dr he/she told me to do the repeat test after 4 days. She is not telling me what are the deficiency in report(attached). My mrs has very mild synonyms and did not develop any further symptoms as now. She is fine but having little bit weakness. It has been  already 11 day past we both has no symptoms. In this regard I just want to know when should we have to do repeat RT-PCR so that we may travel to our destination. Is child of 5 years required to be done covid test? please guide I am so much confused. please
