@casolari4 On a federal tax return lost wages are never deductible. How each individual state handles this type of donation will be addressed in the state program.
IRS Publication 502 Medical and Dental Expenses - https://www.irs.gov/pub/irs-pdf/p502.pdf
You can include in medical expenses amounts paid for medical care you receive because you are a donor or a possible donor of a kidney or other organ. This includes transportation.
You can include in medical expenses amounts you pay for transportation to another city if the trip is primarily for, and essential to, receiving medical services. You may be able to include up to $50 for each night for each person.
