GASTROENTEROLOGY PROCEDURES
It is mandatory to present your medical prescription to be able to carry out the tests.
If you are a pregnant woman or if you suspect that you may be so, or if you are breast-feeding,
please notify it to our health staff before performing any test.
All nuclear medicine tests involve the administration of a radiopharmaceutical
with a very low dose of radioactivity, which is eliminated in the following hours through the urinary or digestive routes.
The access of companions to the center is allowed in the case of children and patients who require special attention.
The rest of the patients can come accompanied but, as a health precaution during the pandemic and depending on
the capacity of the waiting room and the criteria of our staff, it is possible that
the companion cannot wait inside the center.
