PRP for hair - blood draw, how much is usually taken?

When drawing blood to prepare PRP,  we use either a 11 ml or 22 ml tube. The 11 ml tube is similar to the collection tubes in clinical laboratories that prepare diagnostic testing. The 11 ml can  prepare approximately 2.4 to 4 mL of high concentration PRP. This is PRP that is 3.8 to 5 times higher than that in the blood. There should be no difference in drawing this tube and what you encounter for Diagnostic blood drawing. We use a device called the Accuvein which shows us the veins in the arm. An experienced phlebotomist is necessary. Find a PRP expert. Ask to see photos.

This will vary by the collection system that your provider uses to process the PRP.  I draw either 30mL or 60mL of blood to process for PRP depending upon the area being treated. I hope helps!Not everyone is a good candidate for this treatment so please see a Board Certified or Board Eligible Plastic Surgeon to evaluate if you may benefit. Good luck!

crw777,Thanks for the question. That depends on how large the area of thinning  is. We typically draw between 60-120 cc. Sincerely, Bernardino A. Arocha, MD

Hello and thank you for your question. The blood required for the procedure is obtained through one needle stick unless there is poor flow from a small vein, or the needle moves etc. The amount of blood required/ drawn is proportional to the size of the area being treated and in average is approximately 16-20 cc for injections ONLY and without microneedling and topical PRP application.

The amount of blood required for PRP treatment depends on the size of the area to be covered and the concentrating ability of the PRP system.Generally speaking the amount drawn varies between 20-60 cc's (2-4 tablespoons).Roughly about 1/3 of that amount becomes usable PRP. In experienced hands the blood draw should take about 1 minute.

Some clinics take 10 mL some take 180 mL. Most machines are around 60. The maximum I've taken has been 180 mL as a great deal of blood can be processed by the Angel centrifuge. There is no standard anything when it comes to PRP - and that includes how much blood was taken. 10 mL comes out fast ... 180 mL comes out slowly.

Hi,
It really depends on which system they are using and how much surface area is being treated.

Thank you for your question. This question is going to have answers all over the place depending on the PRP kit employed in a given office, the level of platelet concentration they are attempting to achieve and the size of the area to be treated. In our office, we draw either 30 or 60 cc depending on the size of the area to be treated with the goal of a 6-8 fold increase in the concentration of the platelets relative to whole blood. I hope this was helpful - Dr. Moore.

It requires much more blood to make PRP than is required for diagnostic testing. 
The exact amount of blood needed is a function of the proprietary system used to prepare the PRP. These vary from 10 ml to 50 ml. The greater the volume of blood collected, the more platelets are collected as well. The size of the area being treated dictates how much blood is needed. 
The blood drawing procedures also vary. Some use a Vacutainer (a test tube with a vacuum) and some use a plain syringe (coated with an anti-coagulant).  Blood-drawing is a matter of practice albeit it is very difficult in some patients to find a suitable vein. Usually the vein in your elbow pit (antecubital fossa) is the best choice but any vein will do. I prefer not to use veins in the back of the hand; even though they are very visible, they also move and are harder to hit than one would think.

Usually we use the 11 ml tube and get about 4-5 mL of highly concentrated PRP.  That works great for us.  Good luck.
