Help with dd kh test kit

[DeadmanZ]

Hi bros.. Do u all have problem reading the color from dd kh test? In its instruction it says that start color will be blue and end will be purple.. Orange for overdose.. But I've tried the test 3 times and all I get was from blue then become yellow then orange.. No purple in between! Any kind soul can advise on this? Thanks!

It may be a bad batch of reagent. I had that a couple of times. The lfs you bought from should be kind to change the reagent for you if you just bought it recently.
