Item 4.01 Changes in Registrant’s Certifying Accountant

On August 25, 2017, the board of directors of Avant Diagnostics, Inc. (the “Company”) dismissed Marcum LLP (“Marcum”) as the independent registered public accounting firm for the Company and its subsidiaries, effective immediately.  

Marcum’s report on the Company's financial statements for the fiscal year ended September 30, 2015 contained an explanatory paragraph indicating that there was substantial doubt as to the Company’s ability to continue as a going concern. Other than such statement, no report of Marcum on the financial statements of the Company for the fiscal year ended September 30, 2015 and through August 25, 2017 contained an adverse opinion or disclaimer of opinion, or was qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal year ended September 30, 2015 and through August 25, 2017: (i) there have been no disagreements with Marcum on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Marcum, would have caused it to make reference to the subject matter of the disagreement in connection with its reports for such periods and (ii) there were no "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K, except certain material weaknesses in the Company’s internal controls over final reporting, as discussed in the Form 10-K for the fiscal year ended September 30, 2015.

The Company provided to Marcum the disclosures contained in this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission and requested Marcum to furnish a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made by the Company herein and, if not, stating the respects in which it does not agree.  A copy of such letter, dated August 31, 2017, is attached hereto as Exhibit 16.1.

Effective August 25, 2017, the Company engaged Weinstein & Co. (“Weinstein”) as the new independent registered public accounting firm for the Company and its subsidiaries.

During the fiscal years ended September 30, 2015 and 2016 and through August 25, 2017, neither the Company nor anyone on its behalf consulted Weinstein regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, or (ii) any matter that was the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or any reportable event (as described in Item 304(a)(1)(v) of Regulation S-K). Weinstein did not provide the Company with a written report or oral advice that they concluded was an important factor considered by the Company in reaching a decision as to accounting, auditing or financial reporting issue.
