Intestinal Permeability Test
It may be carried out to assess damage to the lining of the small intestine
due to inflammation in Crohn's disease.
Medications such as aspirin and other non-steroidal anti-inflammatory drugs (Volterol, Ibuprofen etc.) should also be avoided for 24 hours before the test.
No solid food should be eaten from midnight prior to the test.
At least 2-3 cups of clear fluids (water, fruit squash, black tea or
coffee) should be taken on the morning of the test. This is to ensure
that a good amount of urine will be passed.
You may eat and drink normally 1 hour after the test has begun but no alcohol must be taken until the test is completed.
All urine is to be collected for the next 6 hours into the container
provider. At the end of this period you should try and empty the bladder
to ensure that a full 6 hour collection is obtained. The completed container
should be returned to the Department of Nuclear Medicine as soon as possible.
