How can I keep blood from coagulating in a vial?

Question

I am planning to draw my own blood and store it in a glass vial. What methods can I use to prevent the blood from coagulating while it is in the vial? Additionally, what is the best technique for transferring the blood into the vial without needing to ask my doctor to draw it for me? Would a simple finger prick suffice for this purpose?

Use an orange and black striped topped Vaccutainer.  it contains the correct amount of heprin.  If you don’t draw the blood in a sterile manner, bacteria will most likely destroy the blood though.

Blood in a vial won’t coagulate because it’s a negative feedback process (I won’t go into it right here, it’s not important) what you should be worried about though is that blood left in a vial will separate into red hemoglobin and clearish serum, I don’t think that is what you are looking for in terms of necklace appearance.

I had one of these vial necklaces and I bought for my wife. I used a lance from a blood sugar test kit to draw blood from my fingertip and mixed it with a small amount of contact lens saline solution. It worked great and my wife often wears it. It s better and more personal than a locket with a lock of hair in it.

Well&hellip;there&rsquo;s no way to keep it from coagulating unless you happen to have a tube with an anticoagulant in it (EDTA, Lithium Heparin, etc)&hellip;
