Exhibit 99.1

ERBA DIAGNOSTICS, INC. ANNOUNCES NOTICE OF

NONCOMPLIANCE WITH NYSE MKT CONTINUED LISTING STANDARDS

MIAMI, FL, April 19, 2013 – ERBA Diagnostics, Inc. (NYSE MKT: ERB) (the “Company”), a fully integrated in vitro diagnostics company, announced today that, on April 17, 2013, the Company received a letter from NYSE MKT LLC (the “Exchange”) stating that the Exchange has determined that the Company is not in compliance with Sections 134 and 1101 of the Exchange’s Company Guide (the “Company Guide”) due to the Company’s failure to timely file its Annual Report on Form 10-K for the year ended December 31, 2012 with the Securities and Exchange Commission (the “SEC”). The letter also states that the Company’s failure to timely file its Annual Report on Form 10-K for the year ended December 31, 2012 is a material violation of its listing agreement with the Exchange and, therefore, pursuant to Section 1003(d) of the Company Guide, the Exchange is authorized to suspend and, unless prompt corrective action is taken, remove the Company’s securities from the Exchange.

The Exchange has informed the Company that, in order to maintain its listing on the Exchange, the Company must, by May 1, 2013, submit a plan of compliance (the “Plan”) addressing how it intends to regain compliance with Sections 134 and 1101 of the Company Guide by July 16, 2013 (the “Plan Period”). If the Company’s Plan is accepted by the Exchange, then the Company may be able to continue its listing during the Plan Period, during which time it will be subject to periodic review to determine whether it is making progress consistent with the Plan. If the Company’s Plan is not accepted by the Exchange, then the Company will be subject to delisting proceedings. Furthermore, if the Plan is accepted by the Exchange, but the Company is not in compliance with the continued listing standards of the Company Guide by July 16, 2013, or if the Company does not make progress consistent with the Plan during the Plan Period, then the Exchange staff will initiate delisting proceedings as appropriate. The Company is working diligently to submit the Plan by May 1, 2013 and to regain compliance with the Company Guide by July 16, 2013.

As previously disclosed in its Notification of Late Filing on Form 12b-25 filed with the SEC on April 2, 2013, and in its Current Report on Form 8-K filed with the SEC on April 17, 2013, the Company has delayed filing its Annual Report on Form 10-K because of unforeseen delays in connection with completing and filing the Company’s consolidated financial statements and the accompanying footnotes, which include the Company’s recently acquired subsidiaries – Drew Scientific, Inc., JAS Diagnostics, Inc. and Drew Scientific Limited Co. Until these matters can be resolved, the Company will not be in a position to file its Annual Report on Form 10-K with the SEC. Pursuant to Rule 12b-25 under the Securities Exchange Act of 1934, the Company received an extension until April 16, 2013 to file its 2012 Annual Report on Form 10-K, which extension has now expired. The Company is working diligently to complete and file its Annual Report on Form 10-K with the SEC, which, as previously disclosed, the Company expects to do on or prior to May 15, 2013.
