Kidney Transplant: Who Can Donate a Kidney and How Is a Match Checked?

A living kidney transplant can offer suitable patients with advanced kidney failure an alternative to long-term dialysis.

One of the first questions families usually ask is:

“Who can donate a kidney?”

Who Can Become a Kidney Donor?

A living donor generally needs to be an adult in good enough health to undergo surgery safely.

Evaluation usually looks at:

• Kidney function

• Blood pressure

• Blood sugar

• Heart and lung health

• History of kidney disease

• Infection risk

• Overall physical and psychological fitness

A willing donor is not automatically accepted. Donor safety comes first.

Does the Blood Group Need to Match?

Blood-group compatibility is important, but transplantation has become more advanced.

In selected centres and suitable patients, transplantation may sometimes be possible even when blood groups are incompatible, using specialised protocols.

The transplant team determines whether this is appropriate.

How Is Kidney Matching Done?

Testing may include:

Blood grouping: Checks compatibility between donor and recipient.

HLA testing: Looks at certain immune-system markers.

Crossmatch testing: Determines whether the recipient has antibodies likely to attack the donor kidney.

Other antibody tests may also be required.

Is the Donor Also Fully Evaluated?

Yes.

Donors undergo detailed tests to ensure they can safely live with one kidney.

This may include imaging of the kidneys, laboratory tests and consultations with different specialists.

What Happens After Donation?

Most carefully selected kidney donors can live healthy lives with one kidney.

However, regular follow-up, blood pressure monitoring and maintaining a healthy lifestyle remain important.

Conclusion

Kidney donation is not simply based on willingness or blood group.

Both donor and recipient undergo detailed medical and compatibility testing before transplantation.

The goal is to achieve the safest possible outcome for both individuals.
