Brief Answer:
There are newer tests available.

Detailed Answer:
Hi,

Thank you for your query.

1. False positive results with Mantoux skin test (Tuberculin Test) can occur due to many reasons.

2. In such cases a TB Gold (QuantiFeron) test is recommended. A TB PCR test, a Hain's test and sputum for AFB x 3 can also be done.

3. The ESR test has prognostic value and a single reading cannot be relied on.

4. These tests should settle the issue.

I hope that I have answered your query. If you have any more questions I will be available to answer them.

Regards.
