Brief Answer:
Highly Sensitive.

Detailed Answer:
Welcome To HCM. I am Dr Anshul Varshney. I understand your concern.

Viral PCR testing is highly sensitive test to detect presence of the virus in the body.
We even use the test in very early phase too with true results.

In your case it has been 11 days post exposure, so the results would be considered accurate.

Just to share with you, HCV RNA is performed for Hepatitis C and HBV DNA is performed for Hepatitis B.

I hope you meant that only.

I hope it helps you.

If you have any further query, please ask me.
