Toothpaste Pregnancy Test: What Is It, And Does It Actually Work?

Toothpaste Pregnancy Test: What Is It, And Does It Actually Work?

The tooth paste pregnancy test has taken the internet by storm.

When you’re unsure whether you’re pregnant or not, it can be tempting to try homemade pregnancy tests you’ve found described online or heard about from well-meaning friends. These tests often use readily available household ingredients. While there are many online resources about homemade pregnancy tests, very few of them look at whether these tests are scientifically accurate. The homemade toothpaste pregnancy test took the internet by storm. But what does it involve, and is there any truth about the concept?

In the past, when you sensed the early signs of pregnancy, you’d go down to the chemist to buy a stick test. And then visit your doctor to get the news confirmed. But, women around the world are more and more convinced by the DIY toothpaste pregnancy test. So much so that Google searches for the test are on the rise.

How does the homemade toothpaste pregnancy test work?

To try the toothpaste pregnancy test, you simply need to mix your usual paste with a small amount of urine. According to advocates of the method, if you’re pregnant, the toothpaste will change colour, and sometimes become frothy. If you’re not, it will stay the same.

Can I trust The Results?

Experts have their doubts about the validity of the test. Stuart Gale, owner and chief pharmacist at Oxford Online Pharmacy, told HuffPost that whilst the tests were ‘a bit of fun’, they may only actually measure the acidity of the urine, rather than providing a positive or negative result.

‘The fizz in the toothpaste is caused by the acid in the urine reacting with the calcium carbonate in the toothpaste to give off carbon dioxide,’ he explained.

This is what a positive result supposedly looks like.

‘The more acidic the urine is, the greater the fizz. Whether or not a person is or isn’t pregnant wouldn’t make any difference.’

Professor Mark Kilby, spokesman for the Royal College of Obstetricians and Gynaecologists added ‘When women become pregnant, their bodies begin to produce the hormone human chorionic gonadotrophin (HCG). This can be detected in a woman’s urine by a pregnancy test.”

‘There is no evidence that toothpaste can detect HCG in a woman’s urine, and women should not rely on DIY methods to confirm if they are pregnant or not.’

Toothpaste pregnancy test: What the results look like

To see if the test has any basis in fact at all, one pregnant woman decided to give it a go. Just to see if the results were as expected. Here’s how that went.

Confusingly, this tester IS pregnant, but the toothpaste pregnancy test didn’t seem to react for her either. No fizzing and no colour change – just thinned out toothpaste. It would seem the jury is still out!

What does the research say about the toothpaste pregnancy test?

The homemade pregnancy tests described above have no scientific basis. No research suggests that they’re accurate methods for detecting pregnancy. They’re based on anecdotal evidence only. Furthermore, there’s also anecdotal evidence that urine from nonpregnant individuals can cause the positive reactions described. Fortunately, there are more accurate pregnancy tests available.

Because of the lack of scientific research, we can’t determine the accuracy of the above homemade pregnancy tests. They are urban myths.

When it comes to a subject as emotive and potentially life-changing as pregnancy, it’s important to note that there are more accurate pregnancy tests out there. These include drugstore-bought urine tests and blood tests at your doctor’s office. Pregnancy tests are also available online. In general, you should use a home pregnancy test the day after you miss your period. Some early detection pregnancy tests do the job earlier than that. According to Planned Parenthood, drugstore home pregnancy tests are about 99 percent accurate.

Pregnancy tests are more accurate when you use the first urine of the day. Your pregnancy test won’t be very accurate if it has expired, so it’s important to check the expiry date. It’s best to use multiple pregnancy tests for a more accurate result. If the results are conflicting, call your doctor. By using scientifically sound pregnancy tests, you’ll be saving yourself the potential heartbreak and anxiety of a false result.

If you think you might be pregnant, you can of course try the toothpaste pregnancy test (who knows, it may work for you!), but it’s always best to speak to a healthcare professional to verify the results and get information and advice about what to do next.Did you try the toothpaste pregnancy test when you were pregnant?
