Medical Laboratory Science (MLS) Module 1 Practice Test

The key idea is that CLIA inspections are conducted on a biennial basis. Under CLIA ’88, laboratories are required to be inspected at least every two years to verify ongoing compliance with quality and safety standards. This two-year minimum helps balance ensuring proper oversight with practical scheduling for many facilities. Inspections can occur more frequently if issues arise, such as deficiencies, complaints, or changes in testing procedures, but the mandated minimum is every two years. The other intervals (every year, every three years, or every four years) do not match the CLIA requirement.
