Early Pregnancy Tests -
What are Early Pregnancy Tests and How do They Work?

Early pregnancy tests are a specific type of pregnancy test, for use between 6-15 days after egg fertilization. Early pregnancy tests are specially made to be extra sensitive in detection of pregnancy.

When a woman becomes pregnant, human Chorionic Gonadotropin (hCG) is produced by her system. The amount in her system doubles every 2-3 days following fertilization of the egg.

If sufficient levels of hCG are produced, it can be detected in blood and urine by an early pregnancy test.

Early pregnancy tests are ideal for couples trying to conceive. They let you know quickly if conception has been achieved, there is no need to wait for a missed period.

How do Early Pregnancy Tests Work?

Early pregnancy tests depend on antibodies - Y-shaped proteins that our immune system normally deploys in defense against invading viruses, bacteria or anything else foreign to the body.

Every antibody binds tightly and with high specificity only to certain foreign molecules, or antigens, and this specificity is what guides the immune defenses.

Early pregnancy tests contain special antibodies. When a urine sample is applied some of these antibodies will bind with the hCG if present. These antibodies, along with unbound ones, flow up the test.

At the test region of the early pregnancy test, the bound antibodies bind with other antibodies that are immobilized on the test and form a colored line, showing a positive pregnancy.

The rest of the unbound antibodies continue to flow up the test, and bind at the control line in the same manner, forming another colored line. The control line serves to show that the antibodies flow up the test correctly and the early pregnancy test is working.

How Accurate Are Early Pregnancy Tests?

Early pregnancy tests are 99% accurate in laboratory tests. All our tests have both US FDA 510k and Health Canada Medical Device Licenses, and proven performance.

What can I do to Ensure the Test is Done Error Free?

• Read the early pregnancy test instructions carefully.



• Note how to apply the sample urine. With strip tests you must hold in sample a limited time so you don't apply too much.



• Note when to read the test. Timing is important and results can be invalid before or after this time.



• Use first morning urine - it contains the highest concentration of hCG as it builds up overnight.



• If the control line does not show, the test has been performed incorrectly. Try again with another test.



• If the pregnancy test is negative but you still believe you are pregnant, wait 3 days and test again.
