Specimen Type Describes the specimen type needed for testing
WB Sodium Heparin
WB Sodium Heparin
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.
See Recommendations for Collection of Control Specimens for p50 and REVP in Special Instructions.
A total of 3 specimens are required to perform this profile; all 3 specimens must arrive within 72 hours of draw:
-Whole blood EDTA for A2F, HBEL, IEF
-Whole blood sodium heparin for P50*
-Control: Whole blood sodium heparin for P50*
*Please note: If no sodium heparin patient or control specimens are received, the P50 test cannot be performed.
Container/Tube: Lavender top (EDTA) and green top (heparin)
EDTA: 5 mL
Heparin: 4 mL
1. Immediately refrigerate specimens after draw.
2. Do not transfer blood to other containers.
3. Rubber band patient specimen and control vial together.
1. Patient's age and sex are required.
2. For information on thalassemias and appropriate test ordering, see Thalassemia Tests in Special Instructions.
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 (Supply T576) is available in Special Instructions.
2. Thalassemia/Hemoglobinopathy Information Sheet (Supply T358) is available in Special Instructions.
3. Erythrocytosis Patient Information Sheet (Supply T694) is available in Special Instructions.
4. If not ordering electronically, please submit a Hematopathology/Molecular Oncology Request Form (Supply T241) with the specimen.
Container/Tube: Green top (heparin)
Specimen Volume: 4 mL
1. Draw a control specimen at the same time from a normal, unrelated, nonsmoking individual.
2. Clearly write normal control on outermost label.
3. Immediately refrigerate specimens after draw.
4. Do not transfer blood to other containers.
5. Rubber band control vial and patient specimen together.
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: 2.5 mL/Heparin: 1 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.
