RSTL does not conduct swab and rapid testing for Covid-19.

Regional Standards & Testing Laboratory (RSTL)


  • Metrology Laboratory
  • Microbiology Laboratory
  • Physico-Chemical Laboratory

The RSTL caters to the testing and calibration needs of private industries, local government units and the general public in the region. It accepts food and water samples for Microbiological and Physico-Chemical tests, and calibration and testing services for mass and volume.

Where tests in these laboratories are not available, the OneLab referral system would divert the customer to the nearest laboratory. OneLab uses the Unified Laboratory Information Management System (ULIMS) for easy online access to laboratory services and referrals.
