Ammonia test didn’t turn?

[Binditheaxolotl]

Hey, so last night when I tested my PH, I tested all the other parameters as well. And my ammonia didn’t turn any color at all. Usually it turns a yellow, which means 0, but it didn’t turn any color. I have an API master testing kit. Is this okay? I’ll test it again when I get home from school.
