Before you take the test

Before the blood sampling, please notice the following:

  • Avoid eating, drinking and smoking at least 4 hours before sample collection.
  • The patient is allowed to take prescribed, regular medication. However, kindly report of the use of PPI-medicines to the person who is taking your blood sample, as some medicines may interfere with the secretion of gastric fluids. See the list of medicines which inhibit the secretion of gastric acid:

ranitidine (Esophex, Inside Brus, Ranicur, Ranil, Ranimex, Ranitidin, Ranitidine, Ranixal, Zantac), famotidine (Famotidin, Pepcid, Pepcidin, Pepcid Duo), nizadine (Nizax), proton pump inhibitors lanzoprazole, omepratsole, pantoprazole, esomeprazole, rabeprazole etc. (Lansoprazol, Lansoprazole, Lanzo, Zolt, Losec, Omeprazol, Nexium, Pariet, Somac, Gasterix, Pantoloc, Giasemin, Panzor).

  • In consideration of the wide variety of natural products, herbal formulations, food supplements and non-medical preparations that claim to reduce gastric acid output and reduce inflammation, we recommend abstaining from their usage for at least one week before taking the GastroPanel test. This is simply because there is not enough evidence-based data available to demonstrate how such products might interfere with the GastroPanel marker profile, and result in a possible erroneous interpretation of the test results.
