Blood test indicated- covid+. As per hospital people they did rapid test yday and said covid -ve. Patient has severe cough since the past 4 days and coughs a lot during night. Steam,proning,and warm things constantly given but still his condition is not getting better. His oxymeter reading at home fluctuates between 90-95 however when checked by hospital staff it showed 98. Not sure who is correct and what to do. Hospital says we wont admit patient as he is negative and the other doctor who got the blood test done says he is positive. How can I get rid of his cough? He has sugar as well. Last checked levels were high
