           HEMACARE REPORTS FIRST QUARTER FINANCIAL RESULTS
______________________________________________________________________


       LOS ANGELES - - - - HemaCare Corporation (OTC Bulletin Board: HEMA.OB)
today announced first quarter 2004 results of operations that resulted in a
profit of $246,000, or $0.03 per share basic and diluted, on revenue of
$6,736,000.  This represents the second consecutive profitable quarter since
the implementation of management's restructuring plan in the third quarter
of 2003.  The restructuring plan closed several non-performing donor
centers, principally located in the eastern United States.  All of the donor
centers that were not part of the restructuring plan experienced increased
sales volumes and revenue in the first quarter of 2004, compared with the
same period in 2003.

       Revenue in the first quarter of 2004 was 2.8% less than the $6,931,000
reported in the same period of 2003.  Blood products revenue decreased
$101,000 to $4,845,000, or 2.0%, as a result of the elimination of revenue
generated by operations closed as part of the restructuring plan.  Blood
products revenue from ongoing donor centers increased $678,000, or 16.5%,
from $4,102,000 reported in the first quarter of 2003.  Blood services
revenue in the quarter decreased $94,000, or 4.7%, to $1,891,000 as a result
of a decrease in the number of therapeutic apheresis procedures performed,
primarily in the New York market, and as a result of the closure of the
Company's operations in Illinois, North Carolina, Pennsylvania and Tennessee
in 2003.

       The first quarter results produced a gross profit of $1,431,000
compared with a gross profit of $1,000,000 for the same period in 2003.  The
gross profit percentage in the quarter increased to 21.2% from 14.4% for the
same period in 2003.  This improvement in gross profit is the result of
increases in product prices and increased operational efficiencies realized
from higher volumes.  The Company has taken steps to improve prices on blood
products as part of the renewal of the Company's hospital blood supply

                                    - more -


contracts.  Operational efficiencies resulting from higher volumes at the
ongoing donor centers is one of the benefits from the current strategy to
grow sales volume at existing facilities rather than from opening new donor
centers.

         Commenting on the first quarter results, Judi Irving, President and
Chief Executive Officer, stated, "We are very pleased to report our second
consecutive profitable quarter.  We are especially pleased that our efforts
to focus the organization on growing sales volumes at our ongoing donor
centers has produced higher revenues from all of our centers when compared
with last year.  We believe the successful implementation of our
restructuring plan has helped to eliminate many of the distractions that has
hindered management's ability to concentrate on the key drivers in our
business.  We plan to solidify our improvement in revenue and take further
steps to improve operational efficiency.  We can now dedicate our full
attention to strategies that generate revenue and improved profit margins
for our remaining business activities."

       HemaCare further announced the execution of an amendment to the
existing credit agreement with Comerica Bank that extended the term of the
line of credit to June 30, 2005, and revised the financial covenants to
levels more favorable to the Company.  As of March 31, 2004, the Company was
in full compliance with the revised covenants.

       Finally, HemaCare also announced the termination of the donor center
management contract with Presbyterian Intercommunity Hospital, located in
Whittier, California, in the second quarter of 2004.  The Company recorded
revenues of $555,000 as a result of this contract in 2003, and $165,000 in
the first quarter of 2004.

       HemaCare will be holding an interactive investor conference call on
Thursday, May 13, 2004 at 1:00 pm (Eastern Daylight Time).  Judi Irving,
President and CEO, and Robert Chilton, Executive Vice President and CFO,
