Napa coolant test strips 4106

Hey all,
Ive been searching, Will these test strips work with the Xerex ELC coolant? There seems to be two types of test strips and some work with ELC coolants and some dont.. Im kinda confused.

After more reading it seems that these are the right strips for my ELC coolant.. Ill still wait to see what you guys think though..

Well I used the strips and my freeze point color came out purple... Thats not even on the chart.. I guess I will call the company monday and see what they say. The Nitrate and pH worked fine pads worked good.
I also may possible have a bad headgasket so maybe there is exhaust gases in the coolant messing things up...? I dont have a coolant exhaust gas tester.
