Specimen

Specimen Type:

Whole blood

Container:

Lavender top (EDTA) tube

Alternate tube: Red top tubes will be accepted, but will delay specimen processing to allow for clotting. (SST tubes are Not acceptable.)

Draw Volume:

2 - 6 mL blood

Collection:

All specimens submitted to the Transfusion Service must be appropriately labeled at the bedside with the time and date of collection, and the signature of the individual collecting the specimen. A completed order, either through the HIS or general requisition must accompany each specimen. It is not always necessary to collect a new sample prior to the provision of blood for patients. Consult with the Transfusion Service prior to collecting additional samples if the patient status is unknown.

Special Processing:

Lab Staff: Refrigerate specimen

Patient Preparation:

Refer to Collection of Patient Specimens for full details. The patient must be positively identified when the specimen is collected. The label on the blood specimen must correspond with the identification on the patient’s Medical Record wrist or ankle band (or ED ID) and on the physician’s/practitioner’s orders. The specimen must be timed, dated and signed by the phlebotomist at the bedside.

Sample Rejection:

Gross hemolysis, sample placed in a serum separator tube, specimen tube not properly labeled.

Interpretive

Limitations:

The Medical Record band used to identify the patient at the time of the specimen collection must remain with the patient for the specimen to remain valid. If the band is lost or removed, a new specimen must be collected if needed for pretransfusion testing.

Methodology:

Hemagglutination

Contraindications:

Order a Type and Screen or Crossmatch if a transfusion is necessary
