A public health forum to exchange laboratory methods, quality improvements and educational resources to enhance molecular newborn screening laboratory performance  

Molecular screening brings new and different technologies into the newborn screening laboratory, creating a need for newborn screening (NBS) laboratory resou​rces. APHL collaborates with CDC's Newborn Screening and Molecular Biology Branch (NSMBB)​ to provide information on available molecular methods and quality improvement activities for state newborn screening programs.​

​NBS Molecular Methods

Use the state NBS laboratory assays list (access restricted to NBS lab directors and their delegates) to understand how other NBS programs are currently using their assays and search for the molecular assay that best fits your program's needs​.

Use the links below to discover the different types of automation instruments available, learn about how automation is currently being used in NBS programs and find questions to ask when purchasing a liquid handler:​

Molecular Assessme​nt Program (MAP) Promotes Quality Improvement 

The Molecular Assessment Program (MAP) is a non-regulatory site visit offered by CDC and APHL that is tailored to newborn screening laboratories performing molecular tests.  MAP was developed to assist newborn screening laboratories in determining how to best meet their unique ne​eds using their available resources. 

​​MAP teams are composed of CDC and state public health laboratory scientists, who work with laboratory personnel to assess all molecular testing procedures. Visits are t​ailored to the specific needs of the program and can provide guidance on evaluating ongoing or soon-to-be implemented molecula​r testing procedures.

Read the MAP Testimonials to learn how other labs have benefited from this program.
