Guardian Home Test

I tried a strip today. The instructions say it doesn't matter how the line is..."a line is a line". Well, at first I only saw one line, but when I looked closer I could see a second line, which indicated negative. The second line was VERY light, so light that I had to look close; but it was there.

The last time I tried it the second line was light, but very noticeable.

Does anyone have any knowledge of this and if the very, very light line means I could have an issue even though they say it does not matter how light it is?

They all work that way. A line is a line. They can be very faint.The control line is usually pretty obvious.

This question has been asked and answered many times on here. If it can be photocopied or show up in a pic within the time limit, it's a line. If you are that close though, you may want to consider a mild dilution because slight changes in fluid intake could change those results if the real test is within a day or 3.
