It depends on the amount of people being drawn, but we have had a phlebotomist draw 11 people where each blood draw cost $15. We have heard of blood draws costing up to $25 for a single blood draw. Several factors to consider: is person going to clinic? is phlebotomist at one location? is phlebotomist going to multiple locations (ie homes or businesses)? how many people will be drawn at one time/location? how long will person need to be there?

How long do you keep a tourniquet on?
A tourniquet should not be removed at all. Tourniquets are a LAST RESORT method. They are hard to apply, they cause a lot of pain, and they can lead to the loss of any limb below wherever the tourniquet was applied. However, if the choice is your LIFE or your LIMB, choose the life. Apply the tourniquet and tighten it until the bleeding stops. Secure the stick to make sure the tourniquet does not loosen and DO NOT TOUCH IT. Get the victim to a hospital immediately. Once there, the doctors and nurses are trained in how to remove tourniquets and treat the wounds. If you leave a tourniquet on too long, the person might lose their arm/leg/whatever. If you take it off too soon, they can easily bleed to death.
Why can you only leave a tourniquet on for 60 seconds?
