Foremost, those RT-PCR positive with mild symptoms should go into home isolation ONLY after getting at least a basic checkup by a doctor and getting some basic blood tests done if the doctor advises. Ideal time to do the blood tests will be by 3rd to 5th day after symptom onset. https://twitter.com/yathirigan/status/1391611737107943427

and this has been repeatedly stressed by doctors in media and social media. Those in home isolation should continuously monitor themselves for new symptoms, increase of existing symptoms and at least twice daily oxygen saturation - at rest and after 6 minutes walk.

seek medical help if you have persistent fever >100F, persistent cough - that occurs/increases while you talk or walk around doing routine household activities, and of course if your oxygen saturation falls below 94% at rest or after 6 minutes walk.

there is no way to predict who will develop clotting tendency. as of now, the only thing that can be done is to do D-Dimer blood test and seek medical help if it is elevated beyond the normal range mentioned in the report.
