Babystart Sperm Test

Hey all, I just wanted to know if any of your partners ever used the babystart Sperm test that you can buy in your local pharmacy. My husband used one of the tests (2 in a pack) last night and the color was lighter than the blue color indicated which means low concentration. I wonder how reliable these tests are its says over 97% accurate on the box but I'd read mixed reviews online. We have been TTC for 6mths now and just did the test to see what the result would be should I be worried?
