Thank you very much @loxside! It doesn't matter that you are a minnow. Every vote and every comment is welcome! I am glad that you like my post and i am also happy because i did't know about this test and you make me to read, to learn about it! This is what i expect from steemit!

I guess that is a blood test, because the last years, they found that cancer cells are travelling through the blood! Do you know if they already use it as clinical test? I am going to search for that. Thank you for your information! I love the exchange of this kind of information!
