1 What is Pytest?

Brand: Pytest

Generic: 14c Urea

Pytest is an orally given radiopharmaceutical agent that helps to determine if you have stomach ulcer-causing bacteria, Helicobacter pylori, in your stomach.

Diagnosis is made by measuring the exhaled radioactive carbon dioxide, which is produced from the breakdown of the orally given urea C 14 by the bacteria, if any.

Using this radioactive agent is generally safe, owing to the limited radiation generated by it. Only a doctor trained in nuclear medicine can administer this agent. It is available as a Capsule.
