Best SPF in vivo testing lab in the US or Worldwide? List of options

edited August 2017 in Advanced Questions
I'm shopping around for 10 panel in vivo SPF tests and most companies charge similar amounts, $255 - 290 per subject. It's very hard to know which one to pick, and since it's a significant investment It'd be nice to pick a good one the first time around. So:

1. Which labs are the most punctual?
2. Have the most accurate SPF scores?
3. Have the best customer service?

Here's a list of US labs I've found, let me know if it's missing any and your experience with them. So far I haven't found any suitable labs abroad.


  • Hello Zink,

    I stumbled across your question here and hope that others will respond since I happen to work for one of the 6 labs that you have listed there. As someone who is bias, I will refrain from answering however I am curious as to what you personally feel as well as others is the best in each of the 3 areas you selected.

    I would also like to add the following questions 

    4.) Which if any have you had a problem with for whatever reason?
    5.) Seems the most knowledgeable or offers the best technical support?
    6.) Has been the best value based on all factors + price?

    Also, one of the 6 you have listed is currently under investigation by the FBI, which as of yet I haven't gotten any clarification as to why.
