For me, less than 10 minutes, and the first time my BP dropped 30 points from start to finish. The nurse said to me “you may have just saved your own life”.

How long does it take to fill the bag?

I needed four over about a 3 month period in 2023. They take your BP before and after, fill a bag with blood, throw it away, make sure you are not dizzy or otherwise feeling unwell, and send you on your way.

I start tomorrow. What is the process?

I only needed 3😊
