Test ID: P50    
Oxygen Dissociation, P50, Erythrocytes

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.

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

3. Rubber band patient specimen and control vial together.

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

Forms: If not ordering electronically, submit a Hematopathology/Molecular Oncology Request Form (Supply T241) with the specimen.

 

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.

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.
