On October 1, 2010, Hemacare Corporation's (the "Company") independent registered public accounting firm, Stonefield Josephson, Inc. ("Stonefield"), combined its practice with Marcum LLP (the "Merger"). Accordingly, effective October 1, 2010, Stonefield effectively resigned as the Company's independent registered public accounting firm and Marcum LLP became the Company's independent registered public accounting firm. This change in the Company's independent registered public accounting firm was approved by the Audit Committee of the Company's Board of Directors on October 6, 2010.

The principal accountant's reports of Stonefield on the financial statements of the Company as of and for the two years ended December 31, 2009 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the two years ended December 31, 2009 and through the effective date of the Merger, there were no disagreements with Stonefield on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which if not resolved to Stonefield's satisfaction would have caused it to make reference thereto in connection with its reports on the financial statements for such years. During the two years ended December 31, 2009 and through October 1, 2010, there were no reportable events of the type described in Item 304(a)(1)(v) of Regulation S-K.

During the two years ended December 31, 2009 and through October 1, 2010, the effective date of the Merger, the Company did not consult with Marcum LLP with respect to any of (i) the application of accounting principles to a specified transaction, either completed or proposed; (ii) the type of audit opinion that might be rendered on the Company's financial statements; or (iii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or an event of the type described in Item 304(a)(1)(v) of Regulation S-K.

The Company provided Stonefield with a copy of the foregoing disclosure and requested Stonefield to furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made therein. A copy of such letter, dated October 27, 2010, furnished by Stonefield, is filed as Exhibit 16.1 to this Current Report on Form 8-K/A.
