What blood tests will I need to find out if a patient and a potential donor are a kidney match? First Steps to Transplant A free self-paced online guide to transplant evaluation and getting on the waitlist. Register Today What is Blood typing (ABO compatibility)? If the donor's blood type works with your blood type, the donor will take the next blood test (tissue typing). The Rh factor (+ or -) of blood does not matter. The following blood types are compatible:
So,
If blood types are not compatible, the donor still may be able to donate directly to you using treatments that lower your blood antibody levels. In addition, the donor may consider donating through a paired exchange program which would allow you to get a kidney from another donor who is not a match for their intended recipient. Talk with your transplant coordinator for more information and additional support. What is Tissue Typing? The second blood test measures antibodies to HLA; this test is done for the patient only and is repeated frequently (sometimes monthly but less often dependent upon the transplant program policy). HLA antibodies can be harmful to the transplanted organ and they can increase or decrease over time so they must be measured while waiting for a transplant, immediately before a transplant surgery, and sometimes following transplantation. If a patient has HLA antibodies in their blood, they are considered HLA “sensitized” and it is best to find a donor with HLA types that avoid the HLA antibodies in the patient’s blood. Importantly, HLA antibody levels can change following events such as blood transfusions, miscarriages, minor surgeries (including dental work or fistula replacement) or severe infections and so these events should be told to the nurse coordinator.

Last Reviewed: 01/31/2017 Why is tissue necessary before a kidney transplant?Tissue typing ensures that an organ from a donor will be compatible with its recipient. The process starts with identifying the unique human leukocyte antigens (HLAs) for the organ donor and recipient, either from blood or tissue.
Why is tissue typing necessary before a kidney transplant quizlet?Tissue typing identifies the similarity of the antigens present in both the donor and the recipient.
How is tissue typing done for kidney transplant?Contrary to what it sounds like, tissue typing only involves a simple blood test. The tissue type is what makes someone react to a donated kidney. Normally, tissue type is involved in the process of getting rid of viruses from the body.
What does tissue typing mean?Tissue typing is a procedure in which the tissues of a prospective donor and recipient are tested for compatibility prior to transplantation. Mismatched donor and recipient tissues can lead to rejection of the tissues.
