Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
This is a consultative evaluation in which the case will be evaluated at Mayo Medical Laboratories, the appropriate tests performed at an additional charge, and the results interpreted.
Specimen Type Describes the specimen type needed for testing
Whole Blood ACD-B
Whole Blood EDTA
Whole Blood EDTA
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 arrive within 72 hours of draw.
Container/Tube: Lavender top (EDTA) and yellow top (ACD [Solution B])
EDTA: Two 4-mL tubes
ACD: One 6-mL tube
Collection Instructions: Do not transfer blood to other containers.
1. Patient's age and sex are required.
2. Include recent transfusion information.
1. New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (T576) is available in Special Instructions.
2. Thalassemia/Hemoglobinopathy Patient Information (T358) is available in Special Instructions.
3. If not ordering electronically, complete, print, and send a Benign Hematology Test Request Form (T755) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/benign-hematology-test-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.
EDTA: 3 mL/ACD-B: 2.7 mL
Mild OK; Gross reject
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
