when you donate your blood, how long do you wait till you can give blood again?

Question

i need to know how long it takes the body to re-generate blood after donating. i’m researching for a book i’m writing.

Ms. Juana Fadel · Accepted Answer

At the Red Cross they won’t allow you to donate blood again for another 3 months and plasma everyweek (since it uses very little blood). However your body makes more blood cells every 24 hours to sustain the body but it takes a bit longer since they take so much. I believe it takes about 3-5 weeks to regenerate the lost blood. It’s just a precaution they have set.Hope that helps!

How often can one give blood? Regulations in the United States allow people to donate whole blood once every 56 days. The waiting period between donations can be different for other blood components. For example, donating only platelets in a process called apheresis requires only a 3 day wait before a person can give again. Donating two units of red blood cells through a similar process doubles the waiting period to 112 days.

https://shorturl.im/awfQxFDA says you have to wait 1 year until you can donate blood after getting a tattoo. It’s a Federal law not a State law

Go see the good folks at the Red Cross Blood Bank. They will tell you all about donating blood (whole) and plasma, etc. Good luck. (They may even entice you to leave some of yours, it can’t hurt!)

Again, why the Bloody Hell are people posting answers they don’t know anything about???? If you aren’t sure, folks, leave it alone.In the USA, you can donate blood once every 56 days. You can donate platelets every 3-5 days.

Red cross recommends 8 weeks.

Ms. Juana Fadel · Answer

You are asking 2 different questions. The time between donations and the time it takes for your body to produce cells that you lost after donating are different.

Ms. Juana Fadel · Answer

I’m thinking once every six weeks, Your best bet is to ask someone from The American Red Cross.

Ms. Juana Fadel · Answer

usually 8 weeks

Ms. Juana Fadel · Answer

I think they allow you to donate blood once a week. Then again they may only allow you to donate Plasma once a week. I am not sure which is which.
