Lubniewski: We have reviewed your proposed amendments to the registration statement and have the following comment. In our comment, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by amending your registration statement and providing the requested information.

After reviewing any amendment to your registration statement and the information you provide in response to these comments, we may have additional comments. Unless we note otherwise, our references to prior comments are to comments in our December 16, 2022 letter. Supplemental Response filed December 20, 2022 Potential Modification of Certain Outstanding Warrants, page 21 1. We note the proposed revised disclosure that, "[i]n connection with this offering, [you] may amend the terms of outstanding warrants" originally issued March 21, 2022, to change the exercise price and expiration date to coincide with those of the warrants in this offering, as inducement of the holder(s) of those warrants to participate in this offering. Based on this disclosure and the additional marked changed pages you provided supplementally, it appears you should revise this offering to include the registration of these warrants and identify the existing investor(s) who will receive the repriced warrants in the offering. In addition, tell us why the cost of the warrant repricing should not be included as an offering expense. Refer to Item 511 of Regulation S-K. Finally, John L. Lubniewski HTG Molecular Diagnostics, Inc.
