![]() ![]() How is this possible? Well, the high levels of hCG overwhelm the pregnancy test and it doesn’t bond with them correctly or at all. The hook effect happens when you have too much hCG in your blood or urine. This means you could get a positive pregnancy test at the doctor’s office, or even on an at-home test in some cases, even before you’ve missed your period! Ah, science.īut hCG is also responsible for the hook effect giving you a false-negative pregnancy test. Your blood might have some hCG as early as eight days after ovulation. This gives you a positive pregnancy test. Pregnancy tests pick up hCG in the urine or blood. It’s first made when the fertilized egg burrows into the wall of your uterus during implantation and increases as the embryo grows. You need this hormone for a healthy pregnancy. This can happen during early pregnancy or in rare cases - even into the third trimester, when it’s pretty clear you’re preggers.ĭuring pregnancy your body makes a hormone called human chorionic gonadotrophin (hCG). The hook effect incorrectly gives you a negative result on a pregnancy test. The test isn’t able to properly attach to any or enough of the right kind of molecules. Similarly, too many of one kind of molecule or many different kinds of the same molecule in the body can mess up a lab test. Then, if someone else decides how many tennis balls are on the court by counting how many the tester caught, they’ll incorrectly say none. But suddenly throw hundreds of tennis balls at her, and she’ll duck for cover and not catch any at all. This might sound counterintuitive, but it’s kind of like when you have too many options for jeans or breakfast cereal, so you can’t choose one to buy at all.Īnother analogy for you: A tester who counts tennis balls by catching them can handle a few dozen tennis balls at a time. It happens when the test is, well, too positive. The hook effect will give you a false negative, when you should have a positive result. Technically, you can have a hook effect with any kind of medical lab test: blood, urine, and saliva. ![]() ![]() The hook effect is also called a “high-dose hook effect” or “prozone effect.” It’s a science term for a rare lab test glitch that causes a faulty result.
