What is a
Pregnancy Blood Test?

Our Pregnancy Blood Test measures the amount of the hormone hCG in your blood. HCG is released when a fertilised egg becomes implanted in your uterine wall, and the level of this hormone increases as your pregnancy develops. This test measures the amount of hCG in your blood to give you a positive or negative pregnancy result.

What can I learn from
from a Pregnancy Blood Test?

Our blood test can tell you if you're pregnant, having a singular birth or multiple births (twins or more), and monitor how well your pregnancy is progressing. It is a sensitive test that detects low levels of hCG, so you may be able to find out if you are pregnant sooner than if you used an over-the-counter urine test.

When should I take
a Pregnancy Blood Test?

You can take our Pregnancy Blood Test about six to eight days after you ovulate to find out if you are pregnant. We recommend that you repeat this test if you receive a negative result and your period has not arrived after another three days. You can also take this test throughout early pregnancy to monitor how well your pregnancy is progressing.

Frequently asked questions

Can a pregnancy blood test be wrong?

As with home urine tests, it is possible to end up with false results (both positive and negative) from a pregnancy blood test. However, this is rare.

How soon can a blood test detect pregnancy?

Due to hCG levels rising rapidly in the early days, a blood test can tell you from about six to eight days post-ovulation.

How will my pregnancy blood test results be displayed?

Your results can be found in MyMedichecks. Here you will see a numerical value with the option to click on lab info to expand. This numerical value will correlate to the expected hCG levels at each point in early pregnancy. Your reporting doctor will also relay your results in the doctor’s comments.
