Learn how doctors handle pairing donor and recipient for liver transplants to ensure a safe surgery and successful organ regrowth for both parties.
How Pairing Donor and Recipient Works
A living liver transplant allows a person to receive a healthy organ segment without waiting for a deceased donor. This is possible because the liver can regrow; both the donor and the person receiving the organ will eventually have full-sized livers.
The connection between donor and recipient does not always have to be a close family member. Donors may be friends, coworkers, neighbors, or distant relatives. However, some transplant centers do not allow donations from strangers.
Medical Requirements for Donors
To ensure a safe outcome, medical teams evaluate several health factors:
- Blood Type: Compatibility is essential. Type O donors can give to A, AB, B, or O. Type A can donate to A or AB. Type B can donate to B or AB. Type AB can only donate to AB.
- Physical Health: Donors must have normal blood pressure and be free of HIV, hepatitis, cancer, and heart or liver diseases. They must not have any long-term or active infections.
- Weight and Size: For adult recipients, the donor’s body size should be similar. Most centers require a body mass index (BMI) under 33 to 35.
- Age: Donors are generally between 18 and 60 years old. Recipients may have better outcomes if the donor is under 40, as older livers may have more scar tissue or fat.
Lifestyle and Mental Health Criteria
Beyond physical health, candidates must meet specific behavioral and psychological standards:
- Sobriety: People with alcohol addiction, substance use disorders, or those who drink heavily cannot donate.
- Mental Stability: Candidates must have no history of major mental health issues.
- Motivation: The decision to donate must be sincere. Buying or selling organs is illegal, and donors should not feel pressured into the procedure.
Considerations Before Donating
Donors should evaluate how the process affects their personal and professional lives:
- Employment: Physical strength and energy levels may be lower for a period after surgery, which may impact demanding jobs. Donors must also plan for lost wages.
- Finances: While health coverage typically covers surgery, hospital stays, and transplant-related complications for the recipient, the donor’s own coverage handles unrelated medical needs.
- Logistics: Travel and lodging costs may apply if the donor does not live near the transplant center.
FAQ
Who can be a living liver donor?
A donor can be a relative, friend, or acquaintance, provided they meet health and age requirements. Some centers exclude strangers.
What happens to the donor’s liver after surgery?
The remaining portion of the liver will grow back into a full-sized organ over time.
Is the donor’s medical information private?
Yes. If a person is not a match or decides not to proceed, the recipient is only told the organ was declined; the specific reasons remain private.
