What Is the Waiting Time Between Blood Donations?

The government requires specific waiting periods in between blood donations. These are due to conditions in normal blood replenishment and the donor health.

Function

The body has to replenish its blood supply. Bone marrow creates stem cells which divide and multiply into red blood cells, white blood cells and platelets.

Time Frame

According to the American Red Cross, you can donate whole blood every 56 days, meaning you can donate up to six times a year.

Types

According to the Department of Health and Human Services, plasma and platelet donors can donate more frequently and only have a three day waiting period, as they lose a less significant amount of red blood cells in their specific extraction methods. Donating units of red blood cells, on the other hand, requires an extended waiting period.

Considerations

Blood donors are required to pass a mini-physical. If you fail the mini-physical, due to a low iron level in your blood for example, you will have to wait longer than a healthy donor.

Effects

According to a study at the University College Dublin, blood donors are not satisfied with waiting times, but this does not hamper their desire to donate in the future.
