But at-home pregnancy tests, when taken according to their package directions, are about 99% accurate. After a fertilized egg implants in the uterus lining, the placenta begins to develop and produces increasing amounts of hCG. If you're unsure about how to access this test or how the procedure works please watch this short video.

It also stimulates the thyroid gland 2 and supports the implantation of the blastocyst (which will later develop into the baby). NG PRECISION+ Pregnancy Blood Test is the first all-in-one pregnancy blood test that you can do at home at any time of the day or night (without needing to wait for a first morning urine), with accurate results in 5 minutes. Blood test results are about 99 per cent accurate and can detect lower amounts of hCG than urine pregnancy tests. 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). It’s important to always speak with your provider and get all the support you need to navigate whatever you may be feeling.It is not unusual, even with hospital laboratory tests, for tests from different manufacturers, different batches from the same manufacturer or even different hospital labs using the same test, to give differing results when the levels of hCG are very close to the detection limit of the tests. However, other medications like hormonal contraceptives or antibiotics won’t affect your hCG level 13.

The turn around is brilliant (mostly - there was a glitch during the early part of the Covid pandemic, but that seems to be resolved now). Unlike urine pregnancy tests, you can use a blood test at any time of the day and are unaffected by dilution from drinks. This prospective study, led by the department of Gynaecology, Obstetrics and Reproductive Medicine, Biochemistry, University of Rennes, Faculty Medicine, University of Rennes and INSERM U1242, Rennes, France, included 200 women consulted in early pregnancy units for vaginal bleeding and/or pelvic pain with unknown pregnancy status after medical consultation including a pelvic ultrasound scan. Other options, such as pregnancy blood tests from Medichecks and London Medical Laboratory, require you to mail your sample to an accredited laboratory to interpret results, with a turnaround time of around two days.

Indeed, if the test is performed too early, the hCG hormone level may not be high enough to be detected, which would lead to a negative result. No matter what the reason, if you ever have any questions about your test results, the best thing to do is reach out to your healthcare provider. But just know that a lot of pregnant women will get negative test results during the first few days after the missed period. These include ovarian and testicular cancer along with other conditions that can increase hCG levels.

This measures whether there is any hCG hormone in the blood stream, with a positive or negative result, but won’t tell you how much hCG is present. You can access the results of your at-home Pregnancy Blood Test on your MyMedichecks dashboard, alongside doctor’s advice and any next steps.Urine tests tend to require slightly more hCG to read positive, making false-negative results a bit more likely with urine tests, although the rates are quite low overall. A quantitative pregnancy blood test can help your healthcare provider determine how many weeks you are pregnant. 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.
