Toxicology Approval and
Proficiency Testing Programs

Laboratories that intend to test specimens collected in Pennsylvania for blood lead, erythrocyte protoporphyrin, alcohol and drugs of abuse must obtain the approval of the Division of Chemistry and Toxicology, enroll in the appropriate proficiency testing program(s) administered by the Bureau of Laboratories and continue to demonstrate satisfactory performance.

The Alcohol in Blood and Lead in Blood programs are approved by the United States Department of Health and Human Services Centers for Medicare and Medicaid Service.  Participation in those programs meets the proficiency testing requirements for those analytes under the federal Clinical Laboratory Improvement Amendments.  

The proficiency testing programs are also open to laboratories that do not require approval from the Bureau of Laboratories.

The division also approves testing devices used by law enforcement officials to determine the alcohol content of blood by analysis of a person's breath.
