Medical Test Sites (MTS) Licensing

MTS/CLIA Application Decision Tree

The Washington Medical Test Site (MTS) licensure program is exempt from the Clinical Laboratory Improvement Amendments of 1988 (CLIA). You don't need to apply to Centers for Medicare & Medicaid Services (CMS) for a CLIA number. Your MTS license will contain both your MTS license number and your CLIA number.
