Brief Answer:
Positive sir.

Detailed Answer:
Thanks for query.
Have gone through your reports dear.
As per standard text If average basal values of breath hydrogen is more than 16 parts per million (ppm), it is generally considered as a high value.Your test is positive for SIBO as in your case its 16 ppm.
Hope i was helpful.

What is my next step? Can I get a prescription for treatment via this online service? My gastro doctor said the test was negative so I guess I need a second opinion?

Brief Answer:
Its not a very sensitive test so opinions may vary from doctor to doctor.

Detailed Answer:
Hi again dear,
See the sensitivity of SIBO is less then 50%.This means that in 50 out of 100 patients it gives true results while in others it gives false result.
As quoted earlier basal ppm conc of hydrogen more then 16 is concidered high.Yours is 16 ppm and 14 ppm.So if you were my patient i would have considered you positive and would have given you a prophylactic treatment with Rifaximin 400 mg once daily for10 days.Its always good to be on safe side.I believe that prophylaxis is always better.

You can get a prescription from any primary physcian.Its a safe medicine.

Hope i cleared your doubts dear patient.
