There is a shortage of willing living kidney donors. I would think the Tx center would jump at the offer to be a living donor and at least begin with some preliminaries like health history, blood type etc. This is usually true even if the individual becomes an altruistic donor for someone else or participates in a paired donation. There are 2 other possible reasons. If your donor is adamant about donating to you and you haven’t been approved/ accepted yet for a transplant. Where are you at in your pre-transplant evaluation? (It sounds like that is what is being told to you and your potential donor.) The other reason is a heart breaker and is that your potential donor changed their mind and no one come clean on this to you. I’ve been looking for a living donor for nearly a decade. I’ve been through 2 pre-transplant evaluations, been approved and accepted for transplant but still haven’t found a living donor. I’m inactively listed on UNOS because thank God, my eGFR is in the low 30’s so I’m too healthy for active listing (eGFR 20 or less).
So how are you doing while you wait? What is your eGFR? Are you on dialysis? Where are you at in your pre-transplant evaluation? It can be done in a week to several months depending on the tests you need. Have you been listed with UNOS? Waiting is hard
