How do transplant personnel ensure that a donor organ is a match?

Rejection is a big problem in organ transplants. White cells in the blood patrol our bodies searching for and attacking things that are not made by our own bodies. This is normally useful, since our bodies get rid of of many diseases in this way. However, the white cells will also 'see' that a new organ has been made somewhere else and attack it. Today, many new drugs have been developed to stop the white cells doing this. This means that people who have had transplants can look forward to many years of life.

∙ 11y agoIf you're on the waiting list for an organ transplant, your data is on a huge database with everyone else waiting for a transplant. Whenever a potential donor becomes available, the database is searched for "the most ill person who is the correct match, within the same geographic area as the donor". If there is no-one waiting within same geographic area, the area of search becomes bigger and the organs can be offered to patients of other countries, so long as it is feasible to harvest and transport the organs with enough time left for transplantation.
All organs are matched on blood type and size of donor and recipient. Kidneys are "tissue matched", which is sort-of a more advanced form of blood-type matching. Gender is not matched; there is a tiny benefit of matching for gender but this would be outweighed by doubling the waiting time for an appropriate organ. Ethnicity is not matched, but to a certain extent it is slightly self-matching, since some blood-types are more common in different ethnicities.

Which organ would be appropriate for a donor transplant?
Blood tests have to be done to determine a match.
When doing a stem cell transplant and they cross match a patient what does the donor have to match with the patient in order to donate?
they have to have matching blood types
What is an allogenic transplant?
An "allogenic" transplant is a human-to-human transplant. (A "xenogenic" transplant would be animal-to-human).
Do you have to wait until you are on a liver transplant list to get a living donor liver transplant?
Part of the reason for being placed on a "transplant list" is to wait until a matching donor is found. At that point, the donor is an unknown, only a possibility. However, if you can find a willing person and if the test results match compatibility with your tissues and blood type, then the "waiting list" is not needed. Your next obstacle would be to have insurance willing to pay. With all of those factors met, you'd have the transplant.
What happened in 1954 with transplants?
The first successful kidney transplant was performed (from identical twins - ciclosporin was discovered in the 1970's, so until then the donor had to match perfectly).
What is the purpose of tissue typing?
Tissue typing is done prior to transplantation to ensure as close a match as possible between the donor and the recipient
When physicians perform an organ transplant they choose a donor whose tissues match those of the recipient as closely as possible Which cell components are being matched?
Cell-surface carbohydrates are what they are matching.
What are the advantages of transplantation?
Organ transplants give people a second chance at life. People have to wait years sometimes for a donor to match their blood type and everything necessary to get a transplant done.

Does donor blood type matter in stem cell transplant?
Yes it is possible. The blood cells are produced in the bone marrow so it is only natural, after a bone marrow transplant, for the donated marrow to manufacture blood of the donor's type.
I was told i was in the age bracket for a lung transplant 57 is there a waiting list?
To clarify, the "waiting" part of the concept of a "waiting list" refers to "waiting for a donor", not "waiting until everyone who was here before me to be transplanted". Everyonerequiring a transplant is placed on the waiting list, since they are all waiting for donors (unless they use a living donor).Everyone who requires a transplant (of whatever organ) is on essentially the same waiting list - that way if a donor comes up who matches more than one person (i.e one match for a liver, one for a kidney, one for lungs) it's easy to identify who requires what.
What are the requirements for kidney transplant?
Well obviously your kidney has to be failing. but other than that you have to have below 30% function in your kidney. Note: you can survive with only 1 kidney so its more like below 30% function in 1 kidney When your kidney function is down to 12 -15 % then you will need to do dialysis or have a kidney transplant. For a transplant the donor's kidney has to be suitable for you. Blood types and tissues types are matched to get as close a match as possible. Some body like a close relative is a good donor. The donor should have no major health problems and the recipient should have no other major health problems apart from the kidney failure.
