Frequently Asked Questions
How do home pregnancy tests work?
Home pregnancy tests work by detecting and assessing the level of hcG, the pregnancy hormone, in your urine. Soon after conception increased levels of hcG are produced, and levels continue to rise during the first three months of pregnancy. If there is a significant amount of hcG in your urine, you are probably pregnant.
When can I use the test?
You can test your urine at any time throughout your menstrual cycle, but usually within the 7 days before your period is due the results will be more accurate. For the greatest accuracy, you should test on the first day of your missed period.
How accurate are the results?
Our pregnancy tests have increased sensitivity to ensure that your results are 99% accurate. While most pregnancy tests can only detect hcG levels above 25 mlU/ml, ours can detect levels as low as 15 mlU/ml, which is almost as accurate as using a blood test.
How long is the test result valid? The results should be read after 5 minutes. After 10 minutes, the results may no longer be accurate, as an evaporation line may appear that could be mistaken for a positive result.
What does a positive result look like?
Two bands in the test region indicate that a concentration of at least 15 mlU/ml of hcG has been detected. You are most likely pregnant.
What does a negative result look like?
If only one colour band appears in the control region, the result is negative. This means that hcG concentration in the urine is either not present or too low for detection. You are most likely not pregnant.
What if no lines appear on the test?
No visible bands in either the control or test regions means the results are invalid. This is probably because there is insufficient specimen volume or the test has been used incorrectly. If uncertain results occur, try again with a new test and be sure to follow instructions exactly.
What if the result is invalid?
If results are deemed invalid, either because it has been left longer than 10 minutes or because neither a red line nor the control line have appeared on the test, you should try again with a new test. Do not reuse the same test again.
What might affect the accuracy of results?
Some health conditions may influence an inaccurate result, such as ovarian cysts. However, contrary to popular belief, alcohol, analgesics (pain killers), antibiotics, and birth control pills should not affect the test results.
What are the limitations of the test?
The test only works if you follow the instructions exactly. Make sure you use only as directed and understand the procedure before you begin. For a full list of instructions and precautions, please visit the Instructions page.
What should I do next?
You should confirm the results with your doctor. If you are pregnant, the next steps you should take will be discussed. If you repeatedly fail to conceive, your doctor may help you explore options such as fertility testing.
