They will have a look to see if they can identify the best vein to take the blood from. Once they have found the right vein then they put the tourniquet on to get the blood pressure up.

Preparing the kit and Skin of Patient

After getting ready with their kit, they start to clean that area of skin where they have to insert the needle. All needles are single-use and are kept in a sterile case before use. We connect the needle to a tube with a receiver on the end that accommodates small vacuum bottles.

Diverting Patient Mind is Hard Part

When they prepare to put the needle in then they make sure you’re comfortable and try to distract you a little if necessary. They will encourage patient to look away if patient would prefer. Most patients hardly notice the needle go in and if anything patient will feel a little scratch as it penetrates the skin.

Once the needle is in patient skin shouldn’t feel any further discomfort, but some patients get a little anxious as the blood begins to flow out. As this happens, they change over the bottles to gather all the samples requested by your consultant. Patient can’t feel this happening and it has no impact on the position of the needle in the vein. 

After all Task Completed

Slip the needle out and place a piece of sterile gauze over the affected area. Phlebotomist asks you to hold this in place while they make the needle safe before popping a small plaster on your arm. If patient are feeling faint, there’s no rush to get up and leave. Phlebotomist discards the needle and gloves after blood drawn.
