Figure 5 The picture shows the lateral flow device test to detect the presence of pepsin in saliva (PEP-test; RDBiomed, Hull, United Kingdom). A: A negative test indicates that no pepsin was detected in clinical sample (only C line is colored); B: A positive test, it indicates that pepsin is present in the sample (saliva/sputum). In the both T and C line are colored.
