Is a False Positive Possible?

I am using the Advanced Digital OPK Monitor and a Ferning Microscope. I got a negative ferning, but a positive OPK at Peak, without having a High before it. When I pulled the OPK I noticed there was the control line, but the other line wasn't there. Under the control line and where the second line should be, there was a light blue streak. Is that a false positive, or how should I take that?

Hi Nikki,

Thanks for using our product. 

The lines on the test stick cannot be read by eye and are only there for the optics within the reader. 

As you have a result, this indicates that the test is working as it should be so you can rely on your result. Our test is over 99% accurate at detecting the LH surge prior to ovulation.

Seeing a low to peak result is not uncommon and this can happen if your estrogen level isn’t high enough to be detected by the test, if your hormone changes occur on the same day, if a test is inadvertently missed, or if testing begins too late in your cycle. You can be assured that you’ve still found your two best days to conceive.
