Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

This test is designed to hold the specimen but delay chromosome preparation and analysis while preliminary morphologic assessment is in process.

 

Upon specimen receipt, the specimen will be held in the laboratory. Chromosome analysis will be performed unless the test is canceled (see cancellation policy).

 

If the client notifies the laboratory that chromosome analysis is not necessary, this test will be reported as "canceled." Chromosome analysis will not be performed but a processing fee will be charged.

 

If the client does not notify the laboratory that chromosome analysis is not needed (see cancellation policy), the Heme Chromosome Hold test will be reported as "reflexed" and chromosome analysis will be performed. Depending on the specimen received, the appropriate reflex test will be performed. No processing fee will be assessed for this test as culture charges are included in the reflexed test.

 

Cancellation policy: The test may be canceled by 4 p.m. (central time) 2 business days after the specimen was collected. The client must notify Mayo Medical Laboratories at 800-533-1710 within this time period to cancel chromosome analysis. If no cancellation is received by this time, chromosome analysis will be performed and charged. Weekend communication can be deferred until Monday.
