HEMACARE REPORTS IMPROVEMENT IN SEQUENTIAL SECOND QUARTER
OPERATING PERFORMANCE BEFORE NON-RECURRING EXPENSES

___________________________________________________________________________________

Los Angeles, Calif., August 14, 2007 --- HemaCare Corporation (OTC Bulleting Board: HEMA.OB), a provider of blood products and services for clinical and research applications, today announced second quarter 2007 results. Revenue increased 14% to $9.6 million from the same period of 2006, with a net loss of $413,000 or $0.05 per share basic and diluted. Included is a $326,000 non-recurring charge for severance expenses associated with the June 29, 2007, resignation of Judi Irving as President and Chief Executive Officer. Without severance expense, pro forma net loss for the quarter was $87,000, which represents a sequential improvement of $260,000 when compared to the reported $347,000 net loss for the first quarter of 2007.

Revenue growth was driven by an 18% increase in blood product sales, which were $8 million compared to $6.8 million in the second quarter of the prior year. This gain was due to the August 2006 acquisition of the company’s HemaCare BioScience subsidiary, which supports research and development programs for pharmaceutical and clinical diagnostic companies. Blood services sales grew approximately 1.5% in the quarter.

Total company gross profit was $1.3 million in the quarter, compared to $1.5 million in 2006. This change was primarily due to fewer donor collections resulting from turnover and vacancies in the California donor recruitment staff. In addition, pricing competition restricted the company’s ability to pass along cost increases for staffing, supplies, fuel, and quality control testing. Blood products gross profit percentage was 14% in the quarter compared to 18% in 2006. Changes in geographic sales mix were the principal cause of a $23,000, or 9%, reduction in blood services gross profit.

The second quarter of 2006 did not include executive severance, interest on acquisition related debt or 123R share-based compensation expense for all of the independent directors. When these items are removed from the 2007 general and administrative expenses, the category increased 18.5% when compared to the prior year. This increase resulted from various costs, including professional fees, temporary personnel, facility charges, and implementation of new IT systems that will support future growth.

Sales for the first six months grew 14% as a result of the HemaCare BioScience acquisition, while profits decreased $1.2 million to a net loss of $760,000. A decline in blood products gross profit, the non-recurring severance charge and increased operating expenses were the principal factors affecting first half profitability.

“The Company is addressing operational issues that contributed to the recent decline in profitability, while also focusing on the growth potential in serving research markets,” said Jay Steffenhagen, Interim Chief Executive Officer. “We believe HemaCare BioScience can grow research sales and profits, which when combined with improvements in California clinical products, will continue the quarter to quarter sequential gains seen in this quarter’s pro forma results. In fact, HemaCare BioScience just entered into the largest testing contract in its history.”
