title: Is standardization of pressure and pH measurement in the oesophagus possible to accomplish in the future?
abstract: The interpretation of the manometric results depends on reliable equipment and the technique used. The use of the Bernstein test and the acid clearing test are discussed. The difficulties in obtaining comparable results from long-term pH-measurement with different pH-probes, the placement of the probe and the problems with the position of the subject and the oral intake before or/and during the investigation are dealt with. It is concluded that standardization of the oesophageal function test within different centers are still a major problem, which will take considerable time to solve.
