Specimen Type Describes the specimen type needed for testing

Control
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.

Specimens must arrive within 72 hours of draw.

 

A whole blood sodium heparin specimen and a control specimen are required.

 

Patient:

Container/Tube: Green top (sodium heparin)

Specimen Volume: 5 mL

Collection Instructions:

1. Immediately refrigerate specimens after draw. Keep at refrigerated temperatures 2 to 8 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.

 

Normal Shipping Control:

Container/Tube: Green top (sodium heparin)

Specimen Volume: 5 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.

3. Immediately refrigerate specimen after draw. Keep at refrigerated temperatures 2 to 8 degrees C. Do not freeze.

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.

1 mL

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