My roommate has covid. i had a rapid test at urgent care on saturday and one yesterday, both negative. i am still experiencing symptoms. which included, cough, sore throat, shortness of breath, and nausea. should i get another test done?

Hard to say for sure, depends on the test and what you will do with the result. If your roommate has COVID and you have symptoms, I would tend to assume you have it also despite test results and would encourage you to act accordingly (isolate for at least 5 days, preferably 10) and be careful not to spread it. If test result would change what you do, then yes, get tested again.

Rapid tests can result in false positives or negatives. The best test is the PCR , which is more accurate but make take a few days for the result. Since you have the symptoms you are most likely positive .Stay away from others, wear a mask and get the PCR test now.
