MDA test results using an E2

Has anyone tested an MDA pill with an E2 kit yet??
coz recently i tested a white mitsubishi from up in brisbane.... and the reaction went quite a dark purple (comparable to any other decent pill i've tested, (blue motorolla, pink channel, caps, etc)) but after about 3-5 mins the outside edges of some of the liquid started to go a red-ish tinge... the rest of the liquid stayed purple.
Does this mean it was MDA? or is it supposed to go red-ish at the begining of the reaction?
also, how long are you supposed to watch the reaction for? (ie: the EZ-test reaction is over in the first 10 seconds)

i did test a MDA pill earlier this year. It actually turned reddish purple and then to a darkish purple unlike yours though.
