Medical Test Sites (MTS) Licensing Info, Forms, and Fees

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.

License Types

The type of testing performed determines the MTS/CLIA license category. Select from the following four options: Waived, PPMP, Categorized or Accredited: 

Please note: All applications require an original ink signature to be processed. 

MTS/CLIA Application Decision Tree

To determine which type of MTS license to apply for, first determine if your facility will perform waived, moderate or high complexity tests. You can verify what type of test you are using by searching the test categorization database.

A list of commonly used waived tests is available. If your lab will perform waived complexity tests only, please submit the waived medical test site license.

A list of provider performed microscopic procedures (PPMP) (PDF) is available. These tests must be performed only by a physician, dentist, physician assistant or advanced registered nurse practitioner in conjunction with a patient visit. If your lab will perform waived tests and the PPM procedures, please submit the PPMP medical test site license.

If your lab plans to use moderate or high complexity tests, please submit either the categorized or accredited medical test site license. Under these license types, your facility can also perform waived tests.

  • If you submit the categorized license application, your facility will be inspected by the Medical Test Site program surveyors.
  • If you submit the accredited license application, your facility will be inspected by the accrediting agency that you choose. You will need to send a separate application to your accrediting agency.

Contact the MTS Program at 360-236-4661 if you need help determining what classification of testing you perform.

Waived Medical Test Site License

Only tests approved as waived by the Food and Drug Administration (FDA) can be performed under this category of license.

If licensed healthcare professionals other than those listed above perform the microscopic tests, you DO NOT qualify for this category of license. Instead, please apply for a categorized or accredited license.
