Round 1
Reviewer 1 Report
Dear Authors
You present an interesting research with very useful results. The only recommendation I have is that I think that there are self-citations that are not appropriate in the context.
The study is well designed and written. I could not find any gaps in the analysis. It is well known that the Hb measurement by "finger drop" is not as accurate as venous samples, however, in special occasions it is the best approach and studies like the one presented are lacking in literature. The sample is small but children are also included.

R= Thank you for the comment. We reviewed the document again, and we removed three self-citations from the Introduction and discussion section.

R=Thank you for the comment. We agree that the paper is written using many technical terms but it expresses the main concern of the measurement errors of Hb in capillary drops. We reviewed it again and we made some adjustments to the interpretation in order to clarify the discussion of the findings. In the results section, the changes were minor since results were described as showed in the analysis.
