False elevation of tumor markers: Chromogranin a and gastrin due to use of proton pump inhibitors

Patients on proton pump inhibitors (PPI) therapy had significantly higher fasting serum gastrin and CgA. False positive elevation of markers can lead to misinterpretation of laboratory test results and thus to misdiagnosis or course of oncology monitoring. Patients should be asked before blood sampling blood for CgA and gastrin, if they are taking PPI and, in collaboration with clinicians, have their blood sampled 4 days after stopping the drug.
