Random Blood Type Generator
Blood type generated locally in your browser with the Web Crypto API.
ABO/Rh blood types
Generate one random blood type from the eight canonical ABO/Rh values (O+, O−, A+, A−, B+, B−, AB+, AB−). Useful for seeding EHR forms, donor and registry systems, patient fixtures, and other mock healthcare data.
Fair random selection
Each result is selected with browser randomness from the fixed set of eight ABO/Rh blood types, each equally likely. Rangdom uses the Web Crypto API for random generation so the next result is not predictable from previous results. Real-world population frequencies are not applied — the distribution is uniform.
When to use it
Use this generator to fill blood-type fields in EHR forms, donor and registry mockups, patient seed data, and test fixtures where a single random blood type is enough.
