In this case, the test may capture the fragmented hormone rather than the intact hormone. The second scenario occurs when there is more of the fragmented hormone present, which, again, is generally when the pregnancy has progressed. This is referred to as the “hook effect.” The hook effect tends to happen further along in pregnancy, when levels of hCG increase. In the first scenario, when there is too much hCG, the elevated levels of the hormone can essentially overwhelm the test, causing it to produce a false negative. Too Much or Fragmented hCG Hormoneįalse pregnancy test results can also occur if there is too much of the hCG hormone, or if the test captures a degraded form of the hormone, called hCG core fragment, which tends to increase as one’s pregnancy progresses. Urine also tends to be less diluted first thing in the morning, as you likely haven’t consumed any liquids overnight. Price recommends not drinking any liquids for a couple of hours before taking a pregnancy test. If the urine is not concentrated enough, then there may not be enough hCG in it for the test to detect.īecause of this, Dr. Diluted UrineĪnother potential cause of a false pregnancy test is if the urine used for testing is too diluted. It’s recommended you test as soon as you’ve missed your period. This could also occur if someone doesn’t wait long enough after intercourse to take a pregnancy test. If someone tests too early in their cycle, the placenta may not have produced enough hCG for the test to detect it yet.
