Although this test is accurate, all pregnancy tests may give a small number of false positive or false negative results. Alexandria (Australia): Australasian Association for Clinical Biochemistry and Laboratory Medicine; c2022. A pregnancy blood test, also known as a beta-human chorionic gonadotropin (hCG) test, measures the levels of hCG hormone in a person’s blood. Detailed specifications are available in the products’ IFUs (see the Resources section for more details). If you have an hCG level higher than expected for your stage of pregnancy, it’s possible that you miscalculated when you got pregnant, and you’re further along than you thought.

For this test, your blood sample is taken at your provider’s office or the hospital, then sent to a lab for analysis. The NG-Test®hCG Blood Precision and NG-Test®/ hCG Whole Blood are rapid immunoassays for the qualitative detection of human chorionic gonadotropin [1] (hCG) in human whole blood as an aid for the early detection of pregnancy. If you get a negative result on a test that your provider does, ask your provider if you need another test.If you have a uterus and ovaries (and you're ovulating), and you’re having penetrative sex with a penis, you can get pregnant. Predicting the decline in human chorionic gonadotropin in a resolving pregnancy of unknown location. Whenever using an early pregnancy test, you should be aware that not all pregnancies will proceed to term, and it is not uncommon for a positive result to become negative early on in pregnancy.

This might happen if you wait longer than suggested to read your test result, or if the test gets wet. And because hCG hormone appears in blood before it appears in urine, a pregnancy blood test will always help to confirm pregnancy earlier than a urine test. Many of the early symptoms of pregnancy are due to the surge in hCG, and confusingly, they’re very similar to ones you might have right before your period. When a woman becomes pregnant, her body begins to produce hCG, a hormone which is released into the blood where its concentration rises over time.But blood tests can detect pregnancy earlier than a home pregnancy test, about 7-10 days after ovulation. If you are in doubt, you should not limit yourself to a negative test result, especially if your period does not come and certain physiological signs indicate that you are pregnant. But just like with an at-home urine pregnancy test, there’s still a chance you can end up with an inaccurate result, like one that says you’re not pregnant when you really are (a false negative) or one that finds you’re pregnant when you aren’t ( a false positive). False results — either a false negative or a false positive — mainly happen due to using the test incorrectly. Or maybe you’re already pregnant and want reassurance that the first stage is progressing as it should be.

An early pregnancy test result can help women consider lifestyle and health changes such as stopping smoking or drinking alcohol but should be encouraged to speak with their GP before stopping or changing any medication.The presence of the hormone Beta-HCG is used to confirm pregnancy and the quantitative levels of this hormone in your blood can be used to determine the gestational age of your foetus. Only pregnant people have a placenta, which develops shortly after a fertilized egg attaches to your uterine wall.

Urine pregnancy test kits are usually able to detect hCG about 1 week after a missed period, but sensitive blood tests such as SELFCheck, can show if you are pregnant just a few days after conception. The Pregnancy Blood Test is used in hospitals and also meets all the regulatory requirements for self test diagnostics (IVDD 98/79EC) which means that it has been independently reviewed by clinicians and scientists, shown to provide reliable results and is easy to use. Unlike the popular urine test (or peeing on a stick), pregnancy blood tests can offer critical information about an early pregnancy.However, taking it after you miss your period reduces the chance of getting a false-negative result.
