The two labs I hear are the best are "Scientific Health solutions" and the "Clifford" one.

I used the clifford lab. I had to send mine over there (overseas). So they sent me all the information and stuff I would need. Once I got that, I went to a blood lab, and had them take my blood and told them I needed the serum. When they got the serum from it, they rang me. I made sure I told them that this would need to be kept fresh because it was being sent overseas. I cannot remember whether they put it on ice or not, but when I got it took it home and packaged it in the tube like package that the lab had sent me, and put it in the freezer. I also had ice packs too, so that they would stay frozen and keep the package cold when I had to courier it overseas.

Then I arranged a courier to pick it all up in one go the following morning. Made sure that I had everything ready beforehand, all the info the lab needed and then right before the courier came, I put in the serum tube with the ice packs around it packaged up. You also make sure the info on the courier bag is clear with I think an urgent sticker or something like that so that when it reaches the lab, they know they need to test it quickly because it's from overseas. It needs to be as fresh as possible or the testing will not turn out.

It all turned out fine, it reached the blood lab fresh and they tested it as soon as they could. They then sent me back a folder with the results. I think it is well worth doing.

Here is a link to the lab and feel free to get in touch with them. http://www.ccrlab.com./
