A home pregnancy testmeasures the presence of the hormone Human Chorionic Gonadotrophin (H.C.G.) in your urine. H.C.G. is produced in the placenta shortly afterthe embryo attaches to the uterine lining. This hormone then builds up rapidly in your body in the first few days following implantation. Usually H.C.G. can be detected by a home pregnancy test 7-10 days after conception. The further in to the pregnancy you are the higher the levels of H.C.G. in your urine.
When should I do the test?
Tests can be taken at any time of the day. However, we do recommend that you test first thing in the morning when your urine is most concentrated. Do not drink large amounts of fluid in an attempt to increase the volume of urine as this may dilute the urine making H.C.G. more difficult to detect.
How does the test work?
Simply collect a urine specimen in any clean container. Use the pipette (dropper) provided in the foil pack to collect enough urine, squeeze a few drops onto the well at the bottom of the cassette and wait for the result to appear in the test window.
What does the test result look like?
Basically if you get two lines in the test window as in the picture below it means you are pregnant.
How long will it take before I can read the result?
You can read the results after just 3 minutes.
What is the difference between home tests and those done by a doctor?
This test is exactly the same as the one used by NHS hospital laboratories and doctors' surgeries throughout the UK. Occasionally, some women may be given a blood test, but they aren't very different from home pregnancy tests either. Both types look for the presence of H.C.G. in your body.
What should I do with my results?
If your pregnancy test results are positive, you should consult your doctor to discuss your pregnancy and what steps and precautions should be taken next. In addition, if your test is negative and you still suspect you may be pregnant, you may want to confirm your test results with another home pregnancy test a few days later. If you test too early you may get a negative result because not enough of the H.C.G. hormone has built up in your system.
If I see 2 lines but one is fainter than the other is this a positive result?
Yes, if 2 lines appear you are pregnant no matter how faint the lines appear.
Can anything affect the results of these tests?
Drinking alcohol, painkillers, oral contraceptives, antibiotics and other common drugs will not affect the result of these tests. Only medicines that contain H.C.G. can produce a false positive result. If you are unsure about your result or your period has still not arrived you should see your doctor for advice.
