Is Home Pregnancy Testing Reliable?

By Ali McHugh


Home pregnancy tests are accurate if you follow the instructions correctly.

If your test result is positive, then this is almost certainly a good, and accurate indication. However, be aware - results that come back as negative may not be as reliable. Any of the following can impace how accurate the result is:

- Don’t follow the instructions to the letter
- Take the test too quickly

Some medications (see below) can also affect the results.

You can purchase home pregnancy tests over-the-counter at most chemists and many large super markets.

Carrying out a test
When you first get pregnant, your body produces large quantities of the pregnancy hormone, human chorionic gonadotrophin (HCG). Home pregnancy tests detect HCG in your urine.

Make sure that you have read and understood the instructions before you take the test, because pregnancy tests use different methods and the results are often shown differently.

You can test a sample of your urine from the first day of your missed period. If your periods are irregular, you may not be sure when this is.

Check the details to ensure you can have the test at any time of day. Try not to drink a lot before taking the test because it can dilute the level of HCG in your urine.

Positive test results

If the test result comes back positive, it's safe to say that you are almost certainly pregnant. You should contact your GP as soon as possible. Because home pregnancy tests are so accurate, they may not repeat the test.

If you want to continue with your pregnancy, a GP can organise your antenatal care.

Negative test results

If however, the result is negative, you may not be pregnant. However, negative results are not as reliable. As an example, if you do a pregnancy test too early, you could be pregnant, but there may not be enough HCG in your body to give a positive test result.

Pregnancy tests can vary in their sensitivity (how soon they can detect HCG and what level of HCG needs to be present). Usually you'll be able t

Pregnancy tests can vary in their sensitivity (how soon they can detect HCG and what level of HCG needs to be present). Usually you'll be able to find information on the packet about how sensitive your test is.

If you still think you’re pregnant after a negative result, wait a week and try again or see your GP.
