It is a test that evaluates the integrity of the wall of the small intestine. At the same time an analysis of the permeability at the level of the stomach is made. Intolerance to lactose and fructose are also tested.

• What is the importance of intestinal permeability?
  It has recently been discovered that many pathologies, especially in the autoimmune field and also the irritable bowel syndrome are linked to an excessive permeability of the small intestinal wall. The increase in intestinal permeability is caused by damage to the lining of the intestines. Usually the intestines only absorb nutrients and small molecules with less than 40 nanometers. When the lining of the intestine is altered or damaged, larger molecules can be absorbed and enter the bloodstream with multiple effects on immunity and metabolism. As the symptoms are not very specific most cases of increased intestinal permeability are not diagnosed.
• What are the clinical indications for its performance?
  The test has been essentially used in a second line of evaluation when the classic tests do not give us an answer regarding the present symptoms.
• Advantages and limitations?
  The main advantage is that essentially with a single relatively simple and non-invasive test we can detect changes. The procedures are relatively simple (an overnight collection of urine at home) but require a very specific schedule.
  The fact that the lab work is carried out outside Portugal requires the delivery of the products for analysis on a specific schedule.
• Is any preparation needed?
  No special preparation is required, however the instructions have to be read very carefully. Once I have the kit, I am available to give you a short explanation of the procedures.
• Do I need to stop my medication to take the exam?
  It is not possible to get tested if you are taking blood sugar lowering medications. It is important not to take aspirin or anti-inflammatories for seven days.
• How is the exam performed?
  The examination consists essentially of a collection of urine after ingestion of various types of special sugars.
• What happens after the exam?
  The products collected are sent by special courier, the result takes three weeks to return.
• What is the cost of examination?
  The price of the test is €120.00
• What agreements do you have?
  We have chosen not to have any agreements. After payment of the exam a receipt is always issued. You can then submit it along with your doctor’s request for reimbursement from your insurer.
