About the ledger

Finding a plasma donation center should not take an afternoon. Operator sites list their own locations and little else; hours go stale, requirements differ by company, and nothing lets you see what is actually near you. PlasmaLedger puts it in one place.

We list 1,256 donation centers across 46 states and 756 cities — each with its address, opening hours, phone number and the operator’s own eligibility rules. 431 also carry pay figures reported by donors.

About the pay figures

Every pay figure is donor-reported. It is not an official rate, not a quote, and not a promise. Rates change often and vary by person. Always confirm with the center before you travel.

Where the rest comes from

Addresses, phone numbers, coordinates and opening hours are compiled from public listings and operator sites, then checked for internal consistency. Where a figure is missing we say so rather than estimating it.
