FOR IMMEDIATE RELEASE: 

AMERICAN BIO MEDICA APPOINTS COMPANY FOUNDER AS CEO
-- Names President and Director as Board Chairman --

KINDERHOOK, NY, September 27, 2004 -- American Bio Medica Corporation (NASDAQ:ABMC) announced today that its Board of Directors has appointed founder and Director Stan Cipkowski as Chief Executive Officer of the Company. Mr. Cipkowski previously served as CEO from the Company’s inception in 1992 until 2001. The Executive Committee of the Board of Directors had been overseeing management of the Company since the departure of Donal V. Carroll in January 2004. The Company also announced today that its Board has appointed Edmund Jaskiewicz, President and Director, as Chairman of the Board. Mr. Jaskiewicz, 81, had served as Chairman from 1992 until 1999. The six-member Board currently has four independent directors.

Mr. Cipkowski, 56, founded the Company in 1992 and is the inventor of the Company’s primary product line, the Rapid Drug Screen® that was released in 1996. From 1996 until 2001, he grew the organization to sales of $7.5 million with approximately 75 employees offering 20 configurations of its Rapid Drug Screen product and was instrumental in creating the required infrastructure to support the Company’s future growth. Since his resignation from the CEO position in 2001, he has remained actively involved with the Company as an employee, Board member and as one of the Company’s largest individual shareholders.

Daniel W. Kollin, an independent Board Director and a member of the Board’s CEO Search Committee, commented, “We conducted an extensive search of potential candidates for the CEO position, but ultimately, the Board determined that appointing Stan to his former role was in the best interests of the Company and its shareholders. Stan was already involved in the day-to-day running of the Company as a member of the Executive Committee and will provide continuity and a stable source of leadership. His effective management and vision, combined with his unmatched understanding of the Company as its founder, make him the logical choice to lead the Company.”

Mr. Cipkowski said, “I welcome the opportunity to work with the Board and management team as CEO to realize the Company’s full potential as a leading, growing, and profitable provider of drug testing kits. There is a tremendous opportunity to leverage our research and development expertise and existing base of business into exciting new directions as we are currently demonstrating with our recent product releases and our contract manufacturing operations. We are also exploring opportunities to penetrate the clinical market through the establishment of the right strategic alliance. As CEO, I look forward to leading the effort to develop these and other promising opportunities.”

Commenting on Mr. Jaskiewicz’s appointment, Cipkowski added, “We are fortunate to have Ed serve as Chairman once again. Together, Ed and I have worked diligently over the past few years to assemble an independent Board and a top management team with new hires in the areas of finance, sales, and R&D. With the Board and management team transition complete, we look forward to focusing on driving increased value for our customers and shareholders.”
