Found this interesting as many believe to have a chemical or are unsure about the faint 2nd line to result in nothing? What do you guys make of this study....

Study has shown ,They can detect hcg even when your not pregnant as we contain a count from 5 and under in our system...... Only above 25 is considered pregnant due to hormone increases etc....... FRER results level with blood tests?
