To be sure, you\u2019ll likely head to a pharmacy to <strong>get a pregnancy test<\/strong>. When should you take a pregnancy test? How should you interpret the results?<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong>Reliable pregnancy test<\/strong>: here\u2019s what you need to know.<\/span><\/p>\n<h2>The different types of pregnancy tests<\/h2>\n<p><span style=\"font-weight: 400;\">There are mainly <strong>two types of pregnancy tests<\/strong> considered reliable: <strong>urine tests<\/strong> and <strong>blood tests<\/strong>.<\/span><\/p>\n<h3><b>Urine tests<\/b><\/h3>\n<p><span style=\"font-weight: 400;\"><strong>Urine pregnancy tests<\/strong> are <strong>the most commonly used<\/strong> due to their <strong>accessibility<\/strong> and <strong>ease of use<\/strong>. It\u2019s probably the stick you urinate on that comes to mind when you hear the words \u201cpregnancy test.\u201d These tests work by detecting the presence of <strong>the beta-hCG hormone<\/strong> (human chorionic gonadotropin) in urine, secreted by the body as soon as the <strong>egg implants in the uterus<\/strong>.<\/span><\/p>\n<h3><b>Blood tests<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">It\u2019s also possible to take a <strong>blood test<\/strong>, which is even more accurate than urine tests because <strong>the measurements are taken directly from the blood<\/strong> and <strong>interpreted by your doctor or midwife<\/strong>, which <strong>reduces the risk of false positives or false negatives<\/strong>. The same hormone, beta-hCG, is measured\u2014just in the blood this time.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Good to know: in France, <strong>blood tests can be reimbursed by health insurance<\/strong> when prescribed by a healthcare professional.<\/span><\/p>\n<h2><b>Factors affecting test reliability<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The reliability of these pregnancy tests can be <strong>influenced by several factors<\/strong>. Here are the most common ones.<\/span><\/p>\n<h3><b>Pregnancy test: false positives and false negatives<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Using a urine pregnancy test is simple, but certain factors can sometimes <strong>distort the result<\/strong>, leading to false negatives or false positives. Here are a few examples:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Incorrect use<\/strong>: not following the instructions for how to expose the test to urine can lead to inaccurate results. Make sure to read and follow the instructions carefully.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Reading the results<\/strong>: results must be read within the specific time frame indicated in the instructions. Reading too early or too late could give an inaccurate result. Follow the recommended timing for an accurate reading.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Overly diluted urine<\/strong>: if you\u2019ve had a lot to drink before taking the test, the hCG hormone may be diluted in your urine, affecting test sensitivity. That\u2019s why it\u2019s often recommended to take the test with your first morning urine.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Expired test<\/strong>: using a test past its expiration date can affect its accuracy. Always check the date before use.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Testing too early<\/strong>: taking a test before your expected period may not detect the pregnancy hormone if it\u2019s still at a low level.<\/span><\/li>\n<\/ul>\n<h3><b>Test sensitivity<\/b><\/h3>\n<p><span style=\"font-weight: 400;\"><strong>The sensitivity of a urine pregnancy test<\/strong> is also important to consider. Some tests are designed to detect the beta-hCG hormone earlier than others. So, <strong>ask your pharmacist for advice<\/strong> to choose the most suitable test for your situation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Overall, the urine tests available today have <strong>very high sensitivity<\/strong> (around 99%), which means <strong>a positive urine test is 99% reliable<\/strong> (false positives are rare). However, the specificity is slightly lower: <strong>a negative test does not necessarily mean you aren\u2019t pregnant<\/strong>. False negatives are most often caused by incorrect use of the test, as mentioned above.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Good to know: a <strong>blood test<\/strong> can generally detect lower levels of beta-hCG than urine tests, making it <strong>more reliable for early confirmation of pregnancy<\/strong>.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Also note that <strong>a pregnancy test can be positive even if the pregnancy is no longer developing<\/strong> (spontaneous miscarriage) or cannot develop properly (ectopic pregnancy).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Want to learn more?

If your pregnancy is confirmed, your <strong>first prenatal appointment<\/strong> should take place during the first trimester (the earlier, the better!).
