Brief Answer:
Yes you need to wait

Detailed Answer:
Dear sir,

I have gone through your question and I understand your concerns but the PCR test can detect the infection in 60% of cases four days after the exposure and can detect the infection in 80% of the cases after three days from the start of the symptoms...

I hope you find this helpful
