Ordering Laboratory Tests

Under the Laboratory and Specimen Collection Centre Licensing Act, 1990 (LSCCLA), Registrants are authorised to requisition the collection of specimens from a patient in a specimen collection centre or laboratory. Registrants can only requisition a test from a laboratory licensed under the LSCCLA. The authority is limited to the tests listed below.

Registrants are not permitted to:
• requisition a specimen for any other purposes than the performance of these tests,
• requisition any specimen other than a specimen necessary for one of these tests, or
• collect a blood specimen for tests other than the seven tests that may be performed in office.

Registrants are also prohibited from sending specimens to laboratories not licensed under the LSCCLA.
