Two Sample Rule

To ensure patient safety, the transfusion laboratory requires the patient to have been tested on more than one occasion prior to issuing red blood cells.  The two separate samples for Group and Save must have been taken at different times, i.e at different phlebotomy sessions.

It is not acceptable to collect two blood samples at the same time and label them a few minutes apart. Such specimens will be rejected.

Labelling Blood Transfusion Specimens and Request Forms

All specimen tubes MUST be labelled with 4 key identifiers:

  • Patient’s last name
  • Patient’s first name
  • DOB
  • Hospital number (or NHS number for primary care requests)

Blood tubes must be signed and dated.

Addressograph labels, unclear or incorrectly labelled samples will be REJECTED in accordance with national guidance.

 

Blood Group, Antibody Screening, and Cross Match

If you wish to convert a group and screen to a cross match, please phone the laboratory on 01271 322327 (ext. 2327).

Group & screen/save samples are kept for 7 days.

 

Maximum Times for Add-on Requests – Blood Transfusion Samples

All Blood Transfusion samples are retained for 7 days. However, the issue of blood against a Group & Save sample is dependent on recent transfusion history. Please see the Blood Transfusion Policy or contact the Transfusion Laboratory for further details.

 

Specimen Timing Requirements for Transfusion Samples

If a patient has been transfused or had a pregnancy confirmed within the last three months samples for the current transfusion must be less than 72 hours (3 days) old.

If a patient has never had a previous transfusion or not been pregnant with the last three months, samples for the current transfusion are valid for up to 7 days.

Allow 1 clear working day for elective crossmatching. Crossmatched blood is routinely returned to stock after 48 hrs unless discussed with the laboratory.
