Test for Ketamin ?

I had a pill the other night, tested a watery brown colour. It was a bit like MDE, sort of mellow, but then weird things started happening. I didn't know what I was doing or where I was, really distant and trippy. I guess it was Ketamin. Does the test react with Ketamin and is it likely it had MDE in it as well ?

Ketamine does not change color when tested with the E-Z Test.
What you describe, watery brown, sounds like Speed (?) or a herbal E, definitely not an XTC like sustance (then it will go purple)
