Lab Assessment of Antibiotic Resistance Testing Capacity (LAARC)

LAARC is a laboratory assessment tool for use in clinical bacteriology laboratories in low- and middle-income countries. It was developed in 2017 and piloted in numerous resource-limited settings.

It helps laboratories identify and correct laboratory practices that contribute to inaccurate antimicrobial resistance (AR) data.

The Excel-based scoring tool:

  • Is available in English, French, Spanish, and Portuguese
  • Generates numerical indicators of quality and capacity in fifteen domains of laboratory practice
  • Provides detailed real-time heatmaps for immediate visualization of problem areas
  • Flags key responses that require urgent correction
  • Aids development of workplans for improvement
  • Can be used to monitor the status of laboratory improvements over time
  • Allows data to be exported and collated for comparative analysis of multiple laboratories
