Understanding Blood Types

Considerations for A Negative Blood Type

• Blood Donation Frequency: Due to the high demand, A negative blood donors may be encouraged to donate more frequently than those with other blood types. However, donation centers prioritize the health and well-being of donors, so frequency is always discussed and tailored to individual circumstances.
