Terengganu woman among just 50 worldwide with rare ‘golden blood’

SHAH ALAM – A woman from Terengganu has been identified as Malaysia’s only known individual with Rh null blood, one of the rarest blood types in the world, often called "golden blood."

This places her among an estimated 50 people worldwide believed to have this exceptionally rare blood type.

Unlike most people whose blood is classified under the ABO system and the Rhesus factor, Rh null blood lacks all Rh antigens on the surface of red blood cells. Because of this absence, it is considered extremely valuable in transfusion medicine but also carries significant risks for the individual.

The 29-year-old woman first learned about her rare blood type in 2016 after donating blood.

She initially struggled to accept the reality of being the sole known Rh null blood holder in the country.

She later said doctors explained the medical importance and uniqueness of the blood type, helping her come to terms with the responsibility and risks involved.

Over time, she understood that the condition required lifelong awareness and caution.

In 2024, she was involved in a road accident and immediately informed members of the public who rushed to help about her rare blood condition despite being in pain.

She said sharing that information was crucial to ensure she received appropriate medical treatment.

While the blood type is medically significant, she acknowledged that it also poses challenges, particularly when it comes to marriage and pregnancy.

She said such situations require closer monitoring and careful medical management to reduce potential complications.

Beyond the individual case, the discovery has wider implications for Malaysia’s healthcare system.

Detecting Rh null blood requires advanced laboratory screening and specialised expertise, reflecting the country’s growing diagnostic capabilities.

The case also highlights the need for strong coordination between hospitals, blood banks and health authorities to ensure donor records are securely maintained yet quickly accessible during emergencies.

Proper data management, experts said, is critical for rare blood cases.

Genetic counselling has also been identified as an important consideration, as Rh null blood is usually inherited through genetic mutations. Close family members are encouraged to undergo screening to determine whether they may carry the same traits.

From a social perspective, the case has renewed calls for greater public awareness about blood donation.

Health experts noted that blood supplies are not just about quantity, but also about ensuring rare blood types are available when needed.

Overall, the identification of Rh null blood in Terengganu marks a significant milestone for local medical science.

It serves as a reminder that every drop of blood holds immense value, not only for individuals, but for communities and the nation as a whole.
