Does the Toothpaste Pregnancy Test Work?
Although this may have been a test used in the past when modern day pregnancy tests were not available or accessible, there are number of issues you need to consider when evaluating the results of the test.
One of the main things to consider is the cleanliness of the items used in the test. This includes the container, the mixing stick and even the toothpaste. What we may consider to be clean, is not clean by “medical” standards (e.g. think needles) and as a result, contamination is a real possibility and issue.
Another issue to contend with is the quantity of urine and toothpaste used. Even though the above steps mention the amount to used, there is no scientific evidence to back up these quantities. Some sites mention the use of moderate amounts and others mention using a few drops. The instructions widely vary and give cause for concern, especially when it comes to something as important as this.
Lastly and most importantly, there is no scientific evidence reported to support that this method works in any of the reputable medical journals or trustworthy newspaper articles.
In fact, Chief Pharmacist Stuart Gale recently told HuffPost UK that the bubbling or frothing in the toothpaste is caused by the acidity of the urine reacting with the calcium carbonate in the toothpate. He also said that “the more acidic the urine is, the greater the fizz. Whether or not a person is or is not pregnant would not make a difference.” Another pharmacist, Anshu Bhimbat of LloydsPharmacy, also believes this test shouldn’t be taken too seriously as there is no scientific evidence behind it as a method for predicting pregnancy. He also said that “determining whether someone is pregnant is based on hormonal changes, as the test relays on the presence of a hormone called human chorionic gonadotropin (hCG)”. He also said the hormone “is released after fertilisation of the egg and sperm. Fertilisation does not always occur on the same day as intercourse.”
