Instructions
Specimens must arrive within 72 hours of draw.

Forms: Red Cell Membrane Disorders Information Sheet (T706) is available in Special Instruction.
Blood:
1. Immediately refrigerate specimen after draw. Refrigerate at 0° to 4° 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 at refrigerate temperature, carefully following proper handling and shipping instructions.
Additional Information: Patient's age and sex are required.
Slides:
Collect 2 well-made peripheral blood smears (Wright stained or fixed in absolute methanol).
Control:
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. Refrigerate at 0° to 4° 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 samples at all times to ensure the reliability of testing results.
