Specimen Labelling

The complete and accurate labelling of the specimen container(s) in the presence of the patient at the time of collection is essential to patient identification.

Historically, labels have been handwritten. With many hospital computer systems, the use of pre-printed labels has replaced the requirement for hand written labels.

Greater care must be used when labelling specimens with pre-printed labels to ensure that the correct patient's label has been attached to the specimen tube.

All specimens for pre-transfusion testing shall be labelled in that patient's presence with:

• Patient name - full legal last and first names
• ID number (health care number or other unique identifier for outpatients)
• Date of phlebotomy

The following information must also be documented:

• The name, initials or computer ID of the phlebotomist
• The date and time of collection

A final check of labelled specimens prior to leaving the patient's bedside should be performed. This final check is made by comparing all labelled specimens from the patient with the patient's identification band information.

Specimens received in the transfusion service that are insufficiently labelled or illegible must not be used for pretransfusion testing. Policies and procedures must be in place for actions to take when unsuitable specimens are received in the hospital transfusion service.

The importance of correct patient identification and labelling of specimens cannot be overstressed.

Rejection of Specimens

The following list includes, but is not limited to, examples of specimens that a hospital transfusion service should not accept for testing:

1. The specimen is not labelled with the minimum required information.
2. The specimen label is not legible.
3. The identity of the patient is in doubt.
4. The phlebotomist is not identified.
5. The specimen quantity is insufficient.
6. The specimen quality is unsuitable for testing (e.g., diluted with IV fluid, etc.).
