New kidney patient workup
An initial workup for potential kidney transplant recipients consists of ABO typing, HLA Class I (ABC) typing, HLA Class II (DRDQ) typing, a T-cell Antibody Screen, and an autologous lymphocyte crossmatch (if indicated). New kidney patient workups are scheduled through the SHKTP.
Sample requirements:
1-10 ml plain red clot tube
4-10 ml ACD-A tubes
New heart patient workup
An initial workup for potential heart transplant recipients consists of ABO typing, HLA Class I (ABC) typing, and HLA Class II (DRDQ) typing. New heart patient workups are scheduled through the INTOTP.
Sample requirements:
1-10 ml plain red clot tube
4-10 ml ACD-A tubes
Preliminary deceased organ donor workup
The initial workup for a deceased organ donor consists of ABO and CMV testing, HLA Class I (ABC) typing, HLA Class II (DRDQ) typing, and deceased donor preliminary crossmatches. Test results are reported immediately to LCNW for allocation of donor organs. Preliminary deceased organ donor workups are coordinated by LCNW.
Sample requirements:
1-10 ml plain red clot tube
3-10 ml ACD-A tubes
OR
1-10 ml plain red clot tube
2-3 Pre-procurement lymph nodes
Preliminary workup for potential living kidney donor(s)
When a kidney transplant patient has potential living donors, the HLA lab performs ABO typing, HLA Class I (ABC) typing, and HLA Class II (DRDQ) typing on the patient and each potential donor. Additionally, a cytotoxic lymphocyte crossmatch and flow cytometric lymphocyte crossmatch (if indicated) are performed between the patient and each potential donor. Preliminary living donor studies are scheduled through the SHKTP.
Sample requirements (for patient and donor):
1-10 ml plain red clot tube
5-10ml ACD-A tubes
Final crossmatch from living kidney donor
Following the preliminary workup but prior to transplantation, a final crossmatch is performed between the kidney transplant recipient and their living donor. The final crossmatch consists of ABO confirmation for patient and donor, cytotoxic lymphocyte crossmatch and flow cytometric lymphocyte crossmatch. Final crossmatches from living donors are usually performed on the day before surgery and are scheduled through the SHKTP.
Patient sample requirements:
1-10 ml plain red clot tube
3-10 ml ACD-A tubes
Donor sample requirements:
1-10 ml plain red clot tube
4-10 ml ACD-A tubes
Final crossmatch from a deceased kidney/heart donor
For kidney and heart transplants, a final crossmatch is performed between the transplant patient and the deceased organ donor. The final crossmatch consists of cytotoxic lymphocyte crossmatch and flow cytometric lymphocyte crossmatch. Final crossmatches from a deceased organ donor are coordinated through LCNW and either SHKTP or INTOTP.
Patient sample requirements:
1-10 ml plain red clot tube
3-10 ml ACD-A tubes
Donor sample requirements:
1-10 ml plain red clot tube
2-3 lymph nodes OR spleen section
Antibody screening for heart transplant candidates
Patients awaiting a heart transplant will have antibody screening performed periodically. If patients have received blood products, they will be screened weekly for at least six weeks following transfusion. Testing involved in antibody screening can potentially include a T-cell antibody screen, FlowPRA I/II screen, and FlowPRA antibody identification.
Sample requirements:
1-10 ml plain red clot tube
Antibody screening for kidney transplant candidates
Patients awaiting a deceased donor kidney transplant must submit samples monthly for periodic antibody screening. Tubes are sent to patients via mailing boxes and are returned to the HLA lab through the mail. Testing involved in antibody screening can potentially include T-cell antibody screen, FlowPRA I/II screen, and FlowPRA antibody identification.
Sample requirements:
1-10 ml plain red clot tube
VAD patient workup
Patients receiving a ventricular assist device (VAD) as a bridge to transplant or as a destination therapy may have samples drawn for a FlowPRA I/II screen, FlowPRA antibody identification and/or HPA1 platelet genotyping. VAD patient workups are coordinated through INTOTP.
Sample requirements:
1-10 ml plain red clot tube (for antibody testing)
1-10 ml ACD-A tube (for HPA1 platelet genotyping)
Post-transplant antibody screening
Following transplantation, antibody screening may be performed in order to assess whether or not the patient is producing antibodies against the transplanted organ. Testing involved in antibody screening can potentially include T-cell antibody screen, FlowPRA I/II screen, and FlowPRA antibody identification.
Sample requirements:
1-10 ml plain red clot tube
Initial workup for potentially refractory platelet patient
HLA antibody screening is performed in order to identify if a platelet recipient has become refractory due to antibodies against HLA antigens. Testing involved can potentially include T-cell antibody screen, FlowPRA I/II screen, FlowPRA antibody identification, and/or HPA1 platelet genotyping. If antibody screening is negative, the patient does not require HLA compatible platelets. If antibody screening is positive, the patient may require HLA-compatible platelet transfusions.
Sample requirements:
1-10 ml plain red clot tube
1-10 ml ACD-A tube
Ongoing support for refractory platelet patient
If a patient serum is positive for HLA antibodies, HLA Class I (ABC) typing and FlowPRA antibody identification is performed to identify compatible platelet products. An HLA compatible platelet donor search is performed to identify suitable donors. Periodically, antibody screening may be repeated to detect newly developing antibodies. Testing may include T-cell antibody screen, FlowPRA I/II screen, and FlowPRA antibody identification.
Sample requirements:
1-10 ml plain red clot tube
1-10 ml ACD-A tube
HLA B27
The presence of HLA B27 has a high relative risk associated with the autoimmune disorder ankylosing spondylitis. The HLA B27 test is a single antigen typing that can assist physicians in the diagnosis of this disease. This test is performed using serologic methods.
Sample requirements:
1-10 ml ACD-A tube
HLA typing or disease association testing
In addition to the test profiles listed, HLA typings may be performed for preliminary identification for donors for bone marrow or stem cell transplantation, vaccine study suitability, or other disease association. An HLA Class I (ABC) typing and/or HLA Class II (DRDQ) typing can be performed as requested by the physician for complete or single antigen HLA typings.
Sample requirements:
1-10 ml ACD-A tube (HLA Class I (ABC) typing)3-10 ml ACD-A tube (HLA Class II (DRDQ) typing)
