Patient's Blood Type and Antibody Screen

Pink Tube (EDTA)

6mL

Lavendeer Tube (EDTA)

The specimen must be labeled at the patient bedside and have two labels: Barcode label with date, accession number, patient name (last, first), medical record number, and test mnemonic .Red label from wristband with patient name, medical record number, time, date, and phlebotomist mnemonic .A red wristband containing patient name, medical record number, time, date, and phlebotomist mnemonic must be put on patient's wrist by person drawing specimen before leaving the bedside.

One or Two Pink Tubes

Room Temperature

Store at 1-6 °C if not tested immediately. Sample can be tested for up to three days after collection.

Grossly hemolyzed specimen; specimen improperly labeled; specimen drawn in wrong tube; quantity not sufficient for analysis

Daily, 24 hours

Typically, 1 hour.

If antibody screen is positive, additional blood may be requested. Antibody Identification can take up to 3 hours.

Does not assure compatibility if blood is required before a crossmatch can be completed. Blood is not crossmatched if only a type and screen is ordered, unless the patient has atypical antibodies. If the antibody screen is positive, additional specimens may be needed for identification and there may be a delay in providing blood for transfusion. Order "Type and Screen" and products needed instead if a patient is likely to need a transfusion within 24 hours or may need a transfusion during labor or delivery.

Determine ABO, Rh, and possible presence of atypical antibody for patients who may require many units of blood in near future. Required preparation for transfusion of certain blood products. When an atypical antibody(ies) is detected, an attempt will be made to identify specificity and to provide at least two compatible units of blood.
