Should i go for a covid test after being exposed to someone that had contact with a positive person? i have no symptoms and its been 7 days since.

Stay at home: Secondary exposure is much lower risk that direct contact - continue to isolate/quarantine for 10-14 days, if no symptoms you are ok. No reason to check for COVID if you are asymptomatic, just make sure you have the proper time of isolation to be safe

No: I would not recommend testing under those circumstances. If symptoms develop, testing may be considered.
