                         between ZeptoMetrix Corporation and Hemagen

              20.2       Press Release of Hemagen Diagnostics, Inc., dated
                         July 23, 1999



On July 23, 1999, Hemagen Diagnostics, Inc. (the "Company") sold all of the
outstanding stock of its wholly owned subsidiary Cellular Products, Inc.
("CPI") located in Buffalo, New York, to ZeptoMetrix Corporation, a company
created by two of CPI's senior managers for the purpose of purchasing CPI.
The purchase price was $800,000 cash.  This price was negotiated as an arms
length transaction.

The unaudited pro forma condensed balance sheet of Hemagen Diagnostics,
Inc. ("Hemagen") as of March 31, 1999 assumes the sale of Cellular
Products, Inc. ("CPI") occurred on that date.

The unaudited pro forma condensed statements of operations for the year
ended September 30, 1998 and the six months ended March 31, 1999 present
the results of operations as if the CPI sale had been consummated as of
October 1, 1997.

The unaudited pro forma condensed financial statements have been prepared
by Hemagen and all calculations have been made based upon assumptions
deemed appropriate.  The disposal of CPI's assets and liabilities has been
presented as if they were sold on the dates indicated.  As a result, the
actual effect of the CPI sale may differ from the pro forma effect
presented herein.

The unaudited pro forma financial information does not purport to be
indicative of the results of operations or the financial position which
would have actually been obtained if the sale had been consummated on the
dates indicated.  In addition, the unaudited pro forma financial
information does not purport to be indicative of results of operations or
financial position which may be achieved in the future.

The unaudited pro forma financial information should be read in conjunction
with Hemagen's historical consolidated financial statements and notes
thereto contained in the 1998 Annual Report on Form 10-KSB and the
Quarterly Report on Form 10-QSB for the quarter ended March 31, 1999.
