Guide to Waived Testing at MCL- Special Topics

Physician performed tests

These have waived status, but may be performed only by physicians within their scope of practice. Physician performed tests allowed by the Medical Center include Strep. A, Heliobacter Pylori and occult blood (e.g. Hemoccult).
 
 

Physician performed microscopy (PPM):

Physician performed microscopic exams include such exams as urine sediment exam, qualitative semen exam, vaginal wet preps, fern tests, etc. These are allowed under CLIA and are also exempt from proficiency testing. The Medical Center allows these procedures to be performed by physicians within their appropriate specialty.
 
 

Regulatory Requirements:

  • The Centers for Medicare and Medicaid Services (CMS) requires institutions performing waived testing to have a Certificate of Wavier. CMS requires that personnel who perform these tests have ongoing competency assessment and that testing procedures are followed exactly in accordance with the manufacturer's instructions.
  • The Joint Commission (TJC) requires laboratory oversight to the performance of waived testing. In addition, the standards require that we answer the following questions:

Question Our answer

Who may perform the test?

The list is maintained by the Nurse Managers.

Which tests will be performed?

See the above list of approved tests.

Where the tests will be performed?

List maintained by the audit section.

Is the test for screening or definitive use?

Hemocue Definitive

All others Screening

  • The MCLNO waived testing policy meets both TJC and CMS requirements. It also describes the oversight process. The policy states that individual units may perform waived tests provided that they meet all requirements. Nurse managers are responsible for maintaining lists of personnel, competency records, quality control records and all other required documentation.

Other Notes:

  • There is a detailed nursing policy for glucose testing and for hemoglobin testing.
  • Procedures for the rest of the waived tests are available, in your waived test binder. These are in a one-page format and cover test performance and quality control requirements.
  • Some tests have internal controls, which are built in to verify that the test is working.
  • Other tests require external quality controls. These are independent sources of positive and negative analytes. (see below)
  • Oversight and audits: The MCLNO policy describes the oversight and audit role.
  • An auditor from the lab makes unannounced visits to verify compliance.
  • Corrective action is required for any discovered deficiencies.
  • The unit manager corrects deficiencies and documents the process in writing.

Competency and Quality Control:

  • All waived tests require that competency be verified on an annual basis. A competency checklist is available for each procedure. Competency verification is reviewed in the audit process. For urine dipstick and pregnancy, colorblind testing is required.
  • Quality Control requirements vary by procedure as summarized in this table:
