Question 1

Is the result from this calculator 100% guaranteed?

Accepted Answer

No, this tool acts as a pre-screening assessment. Final eligibility is determined by the medical staff at your donation appointment based on a physical check of your pulse, blood pressure, and hemoglobin levels.

Question 2

Why am I deferred if I am healthy?

Accepted Answer

Deferrals are often precautionary. For example, if you recently traveled to a country with specific infectious diseases, a deferral period ensures your blood remains safe for patients with compromised immune systems.

Question 3

Does this calculator track my private medical data?

Accepted Answer

High-quality eligibility calculators are designed to be anonymous. They process your inputs to provide an answer without storing your personal identity or private medical records on a permanent server.
