Estimated time remaining until non-IRD transplant *:	3 months 6 months 9 months 12 months 18 months 24 months 30 months 36 months 42 months 48 months 54 months 60 months never
* This is time in addition to the time the patient may have already waited. eg: if a patient has spent 1 year on the waitlist, and the estimated time remaining until a non-IRD transplant is 18 months, the patient is expected to have waited 30 months since listing, before a non-IRD transplant.

When a patient with end stage renal disease (ESRD) on the waitlist for a kidney is offered an Infectious Risk Donor (IRD) kidney, they need to decide whether they will accept the IRD kidney and the associated infectious risk, or if they will decline it and continue to wait for the next available infectious-risk free kidney. Infectious Risk Donors (IRD) are individuals who had high-risk behaviors that puts them at increased risk of transmitting HIV or HCV to recipients of their organs. This calculator is based on data reported to OPTN/SRTR from 2002-2010 and predicts the chance of survival for when the patient chooses one alternative over the other. Some centers use Nucleic Acid Testing (NAT) while others use Enzyme-linked Immunosorbent Assay (ELISA) serology testing on IRD kidneys; in general, the risk of seroconversion with ELISA tested kidneys is 10X greater than NAT.
