Earl Martinez, 28, of Beaverton said he was born with a genetic kidney disease that required him to receive dialysis treatments for four hours three times a week during the past 18 months, KOIN-TV, Portland, Ore., reported Tuesday.
"I definitely don't need money," Martinez said from the roadside. "I just need a kidney."
Martinez said the genetic disease, Alport Syndrome, prevents him from receiving kidney donations from family members.
"Need Kidney Donor," his sign reads.
"My insurance would cover all medical costs on my side and the donors side," Martinez said. "The donor would have no medical costs at all."
