Mycobacterial Culture, Blood
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
When this test is ordered, the reflex tests may be performed and charged.
Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Specimen must be processed within 72 hours of draw.
Preferred: Green top (sodium or lithium heparin)
Acceptable: SPS/Isolator System
Specimen Volume: 10 mL per culture
1. Send specimen in original tube.
2. Please note when sending SPS tube, it must be clearly labeled SPS. If label is obscured, sample may be cancelled as ACD (yellow top) is not an acceptable tube type.
Additional Information: Specimen source is required.
Forms: If not ordering electronically, complete, print, and send 1 of the following forms with the specimen:
Microbiology Test Request Form (T244) (http://www.mayomedicallaboratories.com/it-mmfiles/microbiology_test_request_form.pdf)
Neurology Test Request Form-General (T732) (http://www.mayomedicallaboratories.com/it-mmfiles/neurology-request-form.pdf)
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
Anticoagulants other than heparin or Sodium polyanethole sulfonate (SPS), ACD tube
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
