Living Donor Transplantation Abroad: Medical Evaluation, Ethics and Donor Protection

Living donor transplantation can provide an important treatment pathway for selected transplant patients, particularly in kidney and liver transplantation.

But living donation involves two patients—not one.

The recipient may urgently need transplantation, while the potential donor is usually a healthy person undergoing a medical procedure that provides no direct therapeutic benefit to them.

For that reason, living donor transplantation abroad requires careful protection of both the recipient and the donor.

International patients and families should understand that willingness to donate does not automatically mean a donor will be accepted. Medical suitability, compatibility, informed consent, psychosocial assessment, legal requirements and transplant-center policies all play a role.

This guide explains the major issues patients and potential donors should understand before pursuing a living donor transplant internationally.

What is living donor transplantation?

Living donor transplantation occurs when a living person voluntarily donates an organ—or part of an organ—to another person.

The most established examples include:

living donor kidney transplantation;

and living donor liver transplantation.

In kidney transplantation, a healthy donor may be able to donate one kidney.

In living donor liver transplantation, a portion of the donor's liver may be removed for transplantation because the liver has the ability to regenerate to a substantial degree.

However, both procedures involve real surgical and medical risks to the donor.

WHO's Guiding Principles emphasize that living donors must receive appropriate medical and psychosocial evaluation, give informed and voluntary consent, and receive appropriate follow-up care.

Why do patients consider a living donor transplant abroad?

Patients may explore an international living-donor pathway for several reasons.

They may be looking for:

access to a specialized transplant program;

another transplant-center opinion;

evaluation of a family donor;

expertise in a complex recipient or donor case;

treatment not readily available in their country of residence;

or a hospital experienced in caring for international transplant patients.

However, the fact that a willing donor is available does not mean a transplant can automatically proceed.

The donor and recipient must both satisfy the requirements of the transplant program and applicable law.

Who can be a living donor?

The answer varies by country and transplant program.

Potential living donors may include certain biological relatives or, in some healthcare systems, spouses, partners or other individuals with a genuine relationship to the recipient.

Some jurisdictions may place additional restrictions on living donation involving non-resident patients or unrelated donors.

A transplant center may therefore need to verify:

the donor's identity;

the relationship between donor and recipient;

the donor's medical suitability;

the circumstances of the proposed donation;

and whether the donation is voluntary and lawful.

Patients should not assume that a donor will be accepted merely because they are a family member.

How is a potential living donor medically evaluated?

The evaluation is designed primarily to determine whether donation can occur without exposing the donor to unacceptable risk.

The exact process differs between programs, but evaluation may include:

medical history;

physical examination;

kidney or liver function testing;

blood tests;

imaging;

cardiovascular assessment;

screening for infections;

assessment for underlying disease;

cancer screening where appropriate;

and other organ-specific investigations.

For kidney donors, the transplant team may carefully assess renal function and the potential long-term implications of living with one kidney.

For liver donors, the evaluation may include detailed liver imaging and assessment of the volume and anatomy of the portion that could potentially be donated.

The donor's safety remains a separate clinical priority from the recipient's need for transplantation.

What does compatibility mean?

Compatibility is an important part of living donor transplantation, particularly for kidney transplantation.

Evaluation may consider:

blood group;

HLA characteristics;

recipient antibodies;

crossmatch testing;

donor anatomy;

organ function;

and other clinical factors.

A donor and recipient being related does not guarantee compatibility.

Likewise, incompatibility on one test does not necessarily tell the whole story; some transplant programs have specialized approaches for selected circumstances.

The transplant team must interpret the results and determine whether the proposed transplant is medically appropriate.

Why is independent donor evaluation important?

A potential donor may feel substantial emotional pressure.

A parent may feel that they cannot refuse donation to a child.

A sibling may fear disappointing their family.

A spouse may believe that donation is expected of them.

Financial or social pressures can also be difficult to detect.

WHO therefore stresses the importance of genuine, informed and voluntary choice and recommends that donor motivation and circumstances be appropriately assessed.

An independent evaluation helps ensure that the donor understands the procedure, risks and alternatives and is not being forced, deceived or improperly influenced.

Can a donor change their mind?

A core ethical principle of living donation is that consent must remain voluntary.

WHO's guidance recognizes the importance of allowing a potential donor to withdraw consent before the process reaches a point where stopping would place the recipient in acute danger.

A donor should therefore understand:

that donation is voluntary;

what the procedure involves;

what risks are known;

what alternatives exist;

and at what point withdrawal may no longer be medically possible.

Transplant programs should have procedures designed to protect donor confidentiality and autonomy.

What is informed consent in living donation?

Signing a consent form is not, by itself, sufficient.

Informed consent should involve meaningful understanding.

The donor should receive clear information about:

the surgery;

foreseeable risks;

potential long-term health effects;

recovery;

possible complications;

alternative treatment options for the recipient;

follow-up requirements;

and the right to decline donation.

The Declaration of Istanbul framework emphasizes that consent should be informed and free from deception, coercion and undue influence.

Language differences can make this particularly important in international transplantation. Qualified interpretation may be necessary when the donor does not speak the transplant team's primary language.

Can someone be paid to become a living donor?

Commercial payment for a human organ is incompatible with internationally recognized ethical transplantation principles.

WHO's Guiding Principles oppose financial gain from human organs, while the Declaration of Istanbul defines organ trafficking to include organ removal in exchange for financial gain or comparable advantage.

This does not mean that every legitimate expense associated with donation must necessarily fall on the donor.

Depending on the jurisdiction, legitimate reimbursement of certain reasonable and verifiable expenses may be permitted.

But reimbursement of legitimate expenses is fundamentally different from purchasing an organ.

Patients should be extremely cautious about anyone advertising:

paid kidney donors;

donor packages;

guaranteed organs;

anonymous donors for a fee;

or arrangements designed to conceal financial transactions.

MedTransplant does not sell, source or broker human organs or paid donors.

Why is donor protection especially important in international transplantation?

International transplantation can introduce additional challenges.

These may include:

differences between national laws;

language barriers;

difficulty verifying documents;

economic inequalities between donor and recipient;

differences in consent practices;

and uncertainty about long-term donor follow-up after returning home.

The Declaration of Istanbul has specifically noted that assessing consent in non-resident donors may require additional care because of differences in language, identity documentation and cultural context.

For this reason, a legitimate transplant center should not lower its donor-protection standards simply because the patient and donor are international.

What happens if the donor is not accepted?

A donor can be declined for many reasons.

These may include:

medical risk;

abnormal organ function;

incompatibility;

anatomical concerns;

infection;

psychosocial concerns;

legal restrictions;

or questions about consent or donor motivation.

This does not necessarily mean that anyone acted incorrectly.

The transplant team's responsibility includes protecting a potential donor even when declining that person may be disappointing for the recipient and family.

A responsible international referral service should respect the hospital's decision and should never attempt to bypass donor-safety requirements.

What should patients ask a transplant hospital about living donation?

Before selecting a hospital abroad, patients should ask:

• Does your transplant program accept international living-donor cases?
• What relationships between donor and recipient are permitted?
• What documents are required to establish that relationship?
• Who evaluates the donor?
• Is donor evaluation independent from recipient care?
• What psychosocial assessment is performed?
• How is voluntary consent verified?
• What compatibility testing is required?
• What happens if the donor is declined?
• What follow-up is provided to the donor after surgery?

These questions are at least as important as asking about price or hospital accommodation.

What should international patients prepare before referral?

The recipient and potential donor should generally be treated as two separate individuals in the referral process.

For the recipient, initial information may include:

• diagnosis
• transplant type
• medical history
• current treatment
• laboratory results
• imaging
• relevant specialist reports.

For the potential donor, the transplant center may initially need information such as:

• age
• relationship to the recipient
• general medical history
• blood group where known
• available medical testing.

More comprehensive donor evaluation should be performed according to the transplant center's protocol.

Starting an international living-donor case

A patient—or a trusted representative acting on their behalf—may begin by submitting basic recipient information and noting that a potential living donor is available.

MedTransplant can help organize the initial enquiry and identify potentially relevant transplant programs for independent hospital evaluation.

Living donor kidney transplantation abroad

Kidney transplantation is one of the most common contexts in which international patients may enquire about a living donor.

The donor must have adequate kidney function and meet the transplant center's medical, psychosocial and legal requirements.

Both donor and recipient require separate evaluation.

Living donor liver transplantation abroad

Living donor liver transplantation requires highly specialized evaluation of both donor and recipient.

The donor assessment may include detailed anatomy, liver volume, overall health and surgical risk.

Because living liver donation involves major surgery in a healthy person, donor protection is particularly important.

International patients considering this pathway should seek evaluation only through established liver-transplant programs with clear donor protocols.

What happens after donation?

Donor care should not end when the recipient receives the transplant.

• Living donors may require:
• postoperative monitoring
• wound assessment
• laboratory testing
• pain management
• evaluation of organ function
• activity restrictions during recovery
• longer-term follow-up.

WHO explicitly emphasizes protection of donor health during selection, donation and necessary aftercare.

International donors should ask the transplant hospital how follow-up will continue once they return to their country of residence.

How MedTransplant supports living-donor transplant enquiries

MedTransplant provides international transplant care navigation and patient referral support.

For cases involving a potential living donor, this may include helping patients or trusted representatives:

• identify an appropriate transplant pathway
• organize available recipient information
• indicate the availability and relationship of a potential donor
• explore relevant destinations and transplant programs
• facilitate referral for independent hospital evaluation.

MedTransplant does not decide whether a donor is medically suitable, verify compatibility, approve donation, sell or source organs, or guarantee transplantation.

Those responsibilities remain with the licensed transplant program and relevant authorities.
