Exhibit 99.1

        Pediatrix Agrees to Sell Newborn Metabolic Screening Laboratory

     FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Dec. 19, 2007--Pediatrix Medical
Group, Inc., (NYSE:PDX) has entered into a definitive agreement to sell its
newborn metabolic screening laboratory to PerkinElmer, Inc., (NYSE:PKI).
Specific terms of the cash transaction were not disclosed.

     Pediatrix will focus its resources to support the continued expansion of
its clinical and administrative competencies within the physician services
sector, including anesthesiology. Pediatrix is the nation's leading provider of
neonatal, maternal-fetal, pediatric cardiology and pediatric intensivist
physician subspecialties, and recently launched an initiative to develop a
national group of anesthesiologists with the acquisition of a northern Virginia
practice.

     Pediatrix expects to work with PerkinElmer to identify and conduct clinical
research into possible applications for tandem mass spectrometry technology in
prenatal and neonatal testing and diagnostics to improve patient care.

     Pediatrix will continue to operate its separate, internally developed
newborn hearing screen program, a hospital-based service that screens for
possible hearing loss, usually prior to a newborn's discharge.

     The closing on the sale of the laboratory to PerkinElmer is subject to
customary closing conditions, including the expiration or termination of the
applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976.

     The transaction is not expected to affect Pediatrix's recently issued
earnings per share guidance for 2008.
