Sinungaling, no. Faulty, possible, pero maliit lang na chance. False negatives are extremely rare. Take 2 PTs po para sure, first pee in the morning, midstream. Then make sure to follow the instructions kung paano gamitin and basahin ang results. If di pa rin sure, you can opt for a serum test sa lab, and/or pacheck sa OB. If too early pa po, pwedeng hindi madetect ng PT pero serum tests are more accurate when it comes to that.
hello mommy .. wala pong sinungaling na pt pero may palyado pong PT. possible na nasa pag gamit rin po ang problema if di nasunod yung proper instruction ..
