Who can become an Organ Donor?

There is no particular age to donate organs because all ages can donate and can consider themselves potential donors. If a person wants to donate organs after death, they are evaluated for donor suitability based on their previous medical records and age. The Organ procurement Agency takes into account the suitability of the donors.

The process to Receive an Organ or Tissue

The national Organ Procurement and Transplantation(OPTN) is maintained by UNOS. This UNOS Organ Centre matches organ donors to waiting receipts all days of the year, 24/7 available.

When a certain center receives an organ they send medical and genetic information to UNOS. Then potential recipients list is generated by UNOS, based on the following factors:-

Tissue Type

  • Blood group
  • Size of the organ
  • Patients illness
  • Medical urgency
  • The geographical distance between the recipient and the donor.

First, the organ is offered to the transplant center of the candidate who is the best match. The team at the transplant center decide whether to accept or refuse the organ based on the medical criteria, and other factors include staff availability, patient availability, and organ transportation.

If the transplant center refuses organ-based certain criteria, then the next patient on the list is contacted and continues the process until the organ is successfully placed. First of all, organs are distributed locally, if no match is found, then they are offered regionally and then nationally.

Types of organ transplant

Let’s have a look at various body parts that can be transplanted.

Heart transplant

The first heart transplant was carried out in July 1990 at a hospital in Singapore.

If the donor is suffering from brain death or natural death, the heart is used to replace a patient’s damaged or diseased heart.

They are many complexities in this procedure, so they have been strict medical conditions imposed on the donor’s heart for suitable transplant, and noted the requirements of the potential recipient to receive the transplant.

Due to lack of donors, deceased donors heart transplants are performed thrice to six times a year in Singapore.

Lung transplant

Lungs are replaced from the recently deceased donor to the patient whose one or both lungs are damaged.

Due to strict medical criteria for organ suitability, only nine lung transplants have been performed in the year 2009.

Liver transplant

Healthy liver of the deceased donor is used to replace the diseased liver of the recipient. Livers can be obtained from donors who are deceased or from the family member who chooses to donate part of their liver then liver graft is performed.

This trachea transplant can help patients to soften their hardened and narrowed windpipe.
