Red Blood Cell Membrane Evaluation, Blood

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

Osmotic fragility and eosin-5-maleimide (EMA) binding (Band3) flow cytometry testing will always be performed. A normal shipping control is necessary to exclude false-positive results due to preanalytical artifact. Testing will be canceled if no shipping control is received or if the shipping control is abnormal. A consultative interpretation will be provided.

 

See Benign Hematology Evaluation Comparison in Special Instructions.

Specimen Type Describes the specimen type validated for testing

Control
Whole Blood EDTA
Whole Blood Slide

Shipping Instructions

Specimens must arrive within 72 hours of draw.

Include most recent CBC results.

Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing

A whole blood EDTA specimen, an EDTA control specimen, and 2 well-made peripheral blood smears (Wright stained or fixed in absolute methanol) are required for testing.

 

Patient:

Specimen Type: Blood

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.

2. Label clearly on outermost label normal control.

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.
