Do i need to isolate before going for a covid test once coming into contact with a positive person. the only symptoms i have are a cough and sore throat ?

Yes: To protect others till you know your status you need to self quarantine. Drink plenty of liquids, rest and get the test to help guide your further activities.

COVIDS 19 testing: It is best to wait 5 to 8 days after COVID 19 exposure before testing. Quarantine in the meantime.

See below: Covid-19: https://www.cdc.gov/coronavirus/2019-ncov/index.html Contact your doctor/local hospital, by phone for evaluation and testing in your area. Wear a mask, stay away from others, practice hand hygiene. If you develop breathing difficulty, go to the nearest hospital, immediately. Get Covid vaccine. Wish you good health.
