How the ranking works
Every laboratory is scored against the same four criteria, weighted equally, and reviewed annually.
01 · Accreditation
ISO/IEC 17025 is the entry ticket. SAC, NCEC, A2LA and Aramco approvals add weight.
02 · Scope breadth
Coverage across the five matrices — oil, gas, water, soil and food — and depth of methods within each.
03 · Instrumentation
Modern analytical capability: ICP-MS, GC-MS, IC/TOC, microbiology suites and field monitoring fleets.
04 · Kingdom reach
Physical lab locations, sampling teams and turnaround performance across KSA's industrial hubs.
