Test Code BLOD0944 Baby Type and Screen

Useful For

Preliminary testing for neonatal transfusions.  Because the immunologic system of the newborn is immature and relatively unresponsive to antigenic stimulation during the first four months of life, standards for compatibility testing are different.  Antibody screens in neonates (indirect Coombs) are performed with the mother's serum to screen compatible blood for transfusion of a neonate. Testing also requires a banded specimen from the neonates mother to complete testing.

Methodology

Capture solid phase automation and manual blood banking methods

a. Patient’s full name
b. Patient’s date of birth

c. Date and time of draw

Specimen Rejection: Gel tube

 

Specimen Type: Whole blood (Mother)

Container/Tube: Pink top preferred (K2 EDTA), or Purple top

Specimen Volume: 6 mL

Collection Instructions:  Patient and specimen must be banded.  Do not centrifuge. Forward unprocessed whole blood promptly.

Additional Information:

1. Specimen being drawn may result in a possible transfusion. Patient must be wearing an identification bracelet. Blood Bank identification band must be completed and placed on patient’s wrist at time of specimen draw. If the patitent has no historical blood type at Bozeman Deaconess Hospital, a second draw by a second phlebotomist may be required for transfusion.
2. Identify patient by asking them to state their name. If patient cannot identify himself or herself, find someone who can positively identify patient.
3. Label specimen as follows prior to leaving patient’s side. Using a computer-generated hospital label, or ballpoint pen (press firmly), fill out Blood Bank identification band as follows:
a. Patient’s full name
b. Patient’s date of birth

c. Date and time of draw
d. Phlebotomist’s initials
4. Place 1 label on “Patient Information Here” part of wristband. Remove backing and seal with clear tape.

Ordering Blood Products for a Possible Transfusion

Additional testing must be ordered to prepare blood products for a transfusion.  To receive blood products from the blood bank, the following three steps must be completed:

 

1.  Type and Screen ordered/completed on a banded specimen in the last 72 hours. 

Epic Test Code Test Name Description
BLOD0944 BABY TYPE AND SCREEN Neonate and Mother will be drawn and banded.  Testing will be performed on these specimens to obtain patient ABO, Rh and antibody screen.

 

2.  Prepare and hold ordered for the desired blood product(s).

Epic Test Code Test Name Description
BBAN0009 PREPARE AND HOLD RED BLOOD CELLS (RBC) The number of RBC units requested here will be crossmatched to the patient and held in the blood bank for a possible transfusion over the next 72 hours.
BBAN0010 PREPARE AND HOLD FRESH FROZEN PLASMA (FFP) The number of FFP units requested here will be thawed and tagged for the patient and held in the blood bank for a possible transfusion over the next 24 hours.
BBAN0011 PREPARE AND HOLD PLATELET UNIT (PLT) A unit of platelets will be prepared and tagged for the patient and held in the blood bank for a possible transfusion over the next 24 hours.
BBAN0012 PREPEARE AND HOLD CRYOPRECIPITATE (CRYO) A unit of Cryo will be prepared and tagged for the patient and held in the blood bank for a possible transfusion over the next 6 hours.

 

3.  Request for product ordered to receive unit. 

Epic Test Code Test Name Description
BBRQ0001 REQUEST FOR PRODUCT BLOOD BANK This is a request to have the blood product sent to the hospital location designated on the request.  This should be ordered only after initial type and screen testing is completed, a prepare and hold has been ordered, and patient is prepped and ready to receive blood products.   Patient's blood bank band number must be filled out on this request.
