My Wife, Who Has Two Kids, Turns Out to Be My Biological Older Sister... How Could This Happen?

Tested for Kidney Transplant to Wife, Revealed
"Abnormal Match Rate... Don't Know What to Do"

A story has emerged about a man who was shocked to learn that his wife, with whom he had two children, was actually his biological older sister.

On the 7th (local time), the British daily The Sun reported the story of a British man, Mr. A, who discovered this fact while preparing to donate one of his kidneys to his wife, whose health had recently deteriorated.

Mr. A was adopted by another family just two minutes after birth and grew up happily in an ordinary family with the love of his adoptive parents. After becoming an adult, Mr. A moved to another region for work in 2014, where he met a woman named Ms. B, fell in love, married her, and had two children.

However, Ms. B developed kidney problems after giving birth to their second son. As her condition worsened, she eventually needed a kidney transplant to survive. Unable to find a suitable donor, Mr. A prepared to donate one of his kidneys. There were no issues in the tissue compatibility test for the transplant.

However, the hospital advised Mr. A, “Because some information appeared in the HLA (human leukocyte antigen) tissue test results, it would be better to undergo additional testing,” and he accepted this without much concern.

A short time later, the test results came back, and Mr. A received an unexpected and shocking revelation from the hospital: his wife showed an abnormally high match rate with him.

The hospital explained to Mr. A, “It is rare for spouses to have such a high match rate. The likelihood of a kidney transplant being suitable between parent and child is at least about 50%, and between siblings, it ranges from 0 to 100%.”

Shocked, Mr. A shared his dilemma on an online community, saying, “It has been revealed that my wife and I are biological siblings. I know something is wrong, but I don’t know what to do moving forward.”

In response, a netizen who identified themselves as a researcher working in a clinical laboratory advised, “It could be that you are cousins rather than siblings, or the test results might be incorrect. You should get tested again at another hospital.”
