How long is the first visit and do you have to make an appointment for it??

No appointment just walk in they still have you wear a mask tho...First time is 2 hrs because they do a orentation check up.. minor physical..ask questions..then subsiquent visits after take only an hr you just answer 30 questions on a kiosk then wait to get called back where they take your blood pressure.. stick your finger to check iron and other levels of things in your blood..make sure to be super hydrated because your plasma is 95% water and it makes the process go alot faster and also eat a meal an hour before...then they take your temp and if all good they send you back for the 45min to an hour donation ive made 5.5k since the begining of febuary and its tax free cuz its a donation i average about 5 to 7 hundred bucks a month and that pays my lot rent and utilities and incidentals it really helps in incertain times

2-3 hours depending on how busy they are (early morning and early afternoon are best times to go)and No , no appointment is needed,.it's walk in...

First visit takes about 2hours and you can walk in anytime
