The Department of Laboratories and Research is the behind-the-scenes agency that conducts scientific tests in matters ranging from criminal evidence to public health concerns. The department is headed by Dr. Millard J. Hyland, who is the Chief Medical Examiner.
In 2007, we opened a state-of-the-art DNA Crime Lab that can analyze evidence more quickly and establish identity through DNA with the smallest of samples.
This arrangement groups nearly all county laboratories under a single administrative control, thus permitting interchange of scientific knowledge, technology and data.
Whether it is analyzing crime specimens for DNA, toys for possible lead or drinking water for possible contaminants, the department works to protect the public's health and safety.
 | Environmental Laboratory We provide testing services to a number of government agencies, health officials, engineers, hospitals, schools, businesses, lawyers and others. |
 | Forensic and Toxicology The Division of Forensic Sciences, commonly known as the “crime lab,” provides quality and timely scientific analyses of physical evidence to law enforcement agencies in Westchester County. The division's various units examine a wide aray of evidentiary materials such as blood, tissue, drugs, footwear impressions, fibers, hairs, glass, chemical agents, less-than-lethal force applications and more.

Training involves laboratory diagnosis of viruses, mycobacteria (TB), mycoplasma, ureaplasma, pneumocystis and sexually transmitted diseases. |
