Apart from the areas that are RENAR accredited, the Laboratory SC LACECA SA is able to execute other tests, under non-accreditation regime, either with its own forces and means or by subcontracting. At the same time, the Laboratory SC LACECA SA has the capacity to rapidly implement measures regarding the extension of the range of specific services, on new indicators, methods and standards, according to the requirements of its customers and collaborators.
