You will need to apply for your initial Michigan teacherâs license and your endorsement online through Michiganâs Online Educator Certification System. This will involve creating an account and keeping track of your Michigan Education Information Systems (MEIS) account number.
Donating platelets or double red cells can take longer. The blood donation procedure itself takes about 10 to 12 minutes. But it also takes time to fill out the donor registration form, have a donor history/mini-medical exam, and rest and enjoy refreshments following a donation.
So, whole blood donors are generally required to wait some two to three months to donate a second time. [white cells and plateletes generally renew within a week ] With plasma donation it's a bit different. Unlike whole blood donation, you will have your red blood cells and/or platelets and white cells returned to you.
