A positive Lachman test or pivot test is strong evidence of an existing anterior cruciate ligament (ACL) tear, and a negative Lachman test is fairly good evidence against that injury. Although widely used, the anterior drawer is the least helpful maneuver for diagnosing an ACL tear.
A positive home pregnancy test means that you are pregnant. Home pregnancy tests work by measuring HCG (human chorionic gonadotropic, the pregnancy hormone) in the urine. Unlike blood tests for HCG, which measure the actual amount of hormone, home pregnancy tests just register the presence or absence of HCG. A positive result is quite accurate because the test will not register the presence of HCG unless it is actually there. If your test is positive, you are pregnant. Keep in mind that a home test only measures the presence or absence of HCG. It cannot tell you whether a pregnancy is healthy or whether you have had a miscarriage. You can have a miscarriage and your pregnancy test will remain positive for days or even weeks.
