Bio-Reference Laboratories tests positive as the lab of choice for many in the Northeast. Primarily serving the greater New York metropolitan area, it offers routine clinical tests, including Pap smears, pregnancy tests, cholesterol checks, and blood cell counts. Through unit GenPath, it also performs more sophisticated testing such as cancer pathology and molecular diagnostics. It gets most of its orders (close to 9.6 million per year) from doctors' offices, collecting specimens at draw stations scattered throughout its primary service area in the New York area. Bio-Reference also provides services in nine other states and in Washington, DC. The firm was acquired by Opko Health in a $1.47 billion deal in 2015.
