What is L-SIP?

APHL’s Laboratory System Improvement Program (L-SIP) advances the efficacy of state and local public health laboratory systems through a guided process of performance evaluation, system improvements and periodic evaluation and reassessment. Participating member laboratories receive resources and technical assistance to guide them on their way to system excellence.

Why L-SIP?

Here are some of the benefits that L-SIP produces for state and local public health laboratory systems:

  • Provides a foundation for the accreditation of state and local public health departments by the Public Health Accreditation Board (PHAB).

  • Provides a benchmark for public health laboratory system practice improvements, by setting a “gold standard” to which public health systems can aspire.

  • Improves communication and collaboration by bringing partners (e.g., ​first responders, key constituencies, public health and other laboratories, etc.) together.
