Sperm Count Test?

this is the second at home sperm count test that we have used, the first was positive but it wasn't very dark (it was made like a pregnancy test with two lines) any two lines were considered positive but this test states that the test needs to be as dark as or darker... the control line is green not blue so I don't see how we could judge that? have any of you ever used the EPT male sperm count test & had this issue?
