Find out if you are a match for 14-year-old Thaddeus Giansanti.

A family in Morris County, New Jersey, has made an urgent plea to find a kidney donor for a 14-year-old boy whose one surviving kidney is failing, and doctors believe he needs a transplant as soon as possible.

Thaddeus Giansanti, 14, was born with kidney disease and has already endured multiple surgeries since infancy, and now his only remaining kidney is failing.

After enduring multiple surgeries—including losing a kidney as a baby—his health has taken a sudden turn, and doctors say his best chance at survival is finding a living donor quickly.

Without a transplant in the coming weeks, Thaddeus will likely need dialysis, a life-altering treatment that could drastically change his childhood.

His family is urgently calling for help, hoping someone with O blood type, age 45 or younger, and a healthy BMI will step forward to give him the second chance he desperately needs.

Those who know Thaddeus describe him as kind, strong, and full of heart—a kid whose biggest fight shouldn’t be for his life. Right now, his miracle depends on someone willing to step forward and become his hero.
