How are you guys drawing up the liquid reagent into the syringe, the same way you would do the salifert one right? with a big air bubble and the bottom of the plunger at 1ml.... I did it and got a reading of 7DKH same as my tropic Marin and FM ALK test kit, A buddy of said no, I did it wrong like that and said I didn't add a true 1ml of reagent, he did it and it came out to 10DKH, which reads higher then all 3 of my test kits, TM FM and Salifert.....
