Hemolytic Anemia Evaluation
Specimen Type Describes the specimen type needed for testing
Whole Blood ACD-B
Whole Blood EDTA
Whole Blood Slide
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.
Specimens must arrive within 96 hours of draw.
Two whole blood EDTA specimens, 2 whole blood ACD specimens, an EDTA control specimen, and 2 well-made peripheral blood smears (Wright stained or fixed in absolute methanol) are required for testing.
Container/Tube: Lavender top (EDTA) and yellow top (ACD)
EDTA: Two 4-mL vials
ACD: Two 6-mL vials
Slides: Two peripheral blood smears, Wright stained or fixed in absolute methanol
1. Immediately refrigerate specimens after draw.
2. Send specimens in original tubes. Do not aliquot.
3. Prepare smears.
4. 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. Hemolytic Anemia Patient Information Sheet (Supply T705) is available in Special Instructions
3. If not ordering electronically, submit a Hematopathology/Molecular Oncology Request Form (Supply T241) with the specimen.
Shipping Normal Control:
Specimen Type: Whole blood
Container/Tube: Lavender top (EDTA)
Specimen Volume: 4 mL
1. Draw a control specimen from a normal (healthy), unrelated, nonsmoking person at the same time as the patient.
2. Label clearly on outermost label normal control and also indicate sex of control on same label.
3. Immediately refrigerate specimen after draw.
4. Send specimen in original tube. Do not aliquot.
5. Rubber band patient specimen and control vial 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.
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.
