In this article, ‘Increased neutrophil elastase in affected lobes of bronchiectasis and correlation of its levels between sputum and bronchial lavage fluid’ contained following errors in the text.

1. In the Materials and Methods section, the information regarding the Neutrophil Elastase Activity Assay Kit is incorrect. The kit code (MAK246) is correct; however, the manufacturer information should be revised as follows:

Current: (Fluorometric, MAK246, Abcam, Cambridge, UK)

Correct: (Fluorometric, MAK246, Sigma-Aldrich, Burlington, MA, USA)

2. The units for the stock solution and working solution are incorrect. The unit should be ‘ng/μL’ instead of ng/L.

We sincerely apologize for this mistake and any inconvenience that we have caused.
