Test Catalog

Test ID: HSEP    
Hereditary Spherocytosis Evaluation

Specimen Type Describes the specimen type needed for testing

Control
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.

Specimens must arrive within 96 hours of draw.

 

A whole blood EDTA specimen and a control specimen are required.

 

Patient:

Container/Tube: Lavender top (EDTA)

Specimen Volume: 4 mL

Collection Instructions:

1. Immediately refrigerate specimen after draw. Refrigerate at 0 to 4 degrees C. Do not freeze. Freezing causes sample lysis, and tests will not be performed on hemolyzed specimens.

2. Send specimen in original tube. Do not aliquot.

3. Rubber band patient specimen and control vial together. Control must accompany the patient sample at all times to ensure the reliability of testing results.

4. Be sure specimen and control are stored and transported together at refrigerate temperature, carefully following proper handling and shipping instructions.

Additional Information: Patient's age and sex are required.

Forms: Red Cell Membrane Disorders Information (Supply T706) is available in Special Instruction.

 

Normal Shipping Control:

Specimen Type: Whole blood

Container/Tube: Lavender top (EDTA)

Specimen Volume: 4 mL

Collection Instructions:

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. Refrigerate at 0 to 4 degrees C. Do not freeze. Freezing causes sample lysis, and tests will not be performed on hemolyzed specimens.

4. Send specimen in original tube. Do not aliquot.

5. Rubber band patient specimen and control vial together. Control must accompany the patient sample at all times to ensure the reliability of testing results.

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.

2 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected

Hemolysis

Mild reject; Gross reject

Lipemia

NA

Icterus

Other

Clotted, frozen specimen

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
