Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Comments:

Latent and disseminated TB is still big problem in diagnosis as well as in treatment regimen. In case if smear negative and culture negative TB-HIV case especially in comorbid situation this assay may have great advantages at POCT lavel. Present study of Panraksa, et al. was very nicely done using all methodological aspect to find out the better outcome in TB diagnosis with high sensitivity and specificity. Following suggestions may make more impact on this article:

Abstract:

• Abbreviation must require for TB and Mtb upon first appearance in the text.

Method:

• Advise to put this section before Result and Discussion.

• Ethical statement is missing. Should write in sub-heading in method section only.

• Provide figure in high resolution (Fig 2, Fig 4).

Results:

• Conclusion part is missing

Reviewer #2: I would like to appreciate efforts of the authors to improve Lipoarabinomannan (LAM) assay for the diagnosis of TB. It is beneficial as it is done in non invasive samples (urine) and it should be promoted with improved sensitivity using various pretreatment methods as done in this study.

Immobilization of Proteinase K for Urine Pretreatment to Improve Diagnostic Accuracy of Active Tuberculosis

PLOS ONE

.

To

Professor Seyed Ehtesham Hasnain

Academic Editor

PLOS ONE

Thank you for thoroughly reviewing our manuscript. Below, we have now addressed all your queries and listed these point-by point. All our responses (point by point) are hilited in red and copied below.

The two reviewers were appreciative of the work presented and had very constructive suggestions, which we addressed to the best of our ability. Original SDS/PAGE Western Blot without any edits has been included as a Supplementary material S1 Fig.

Figs 2 and 4 in the manuscript have been replaced with High Resolution Tif Figs. Most importantly. we have included a separate Ethics statement and revised some write ups in the Introduction and Methods and material section. Unfortunately, with me being the corresponding author, the style of writing repeats over time with the usage of similar statements. The edits are clearly visible in the version with tracking.

Hopefully the. resubmission will meet with the Journal style and goals.

Kind regards,

Delphi Chatterjee

Abstract:

• Abbreviation must require for TB and Mtb upon first appearance in the text.

Corrected and changed accordingly

Method:

• Advise to put this section before Result and Discussion.- Done in the resubmitted version

• Ethical statement is missing. Should write in sub-heading in method section only.-Done and introduced Ethics Statement as a sub heading in Methods and material section see p. 7

• Provide figure in high resolution (Fig 2, Fig 4).

Replaced Fig 2 and 4 with High Resolution tif files. We have also used PACE per PLOS ONE guidance to check the submitted Figs quality. Fig 2 has been redrawn.

Results:

• Conclusion part is missing

Conclusion section is now added, see p 18.

Reviewer #2: I would like to appreciate efforts of the authors to improve Lipoarabinomannan (LAM) assay for the diagnosis of TB.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
