Does the bleach pregnancy test work?

What does a positive bleach pregnancy test look like and is it accurate?

Bleach is one of those oh-so handy household products most of us probably have somewhere (if you have little ones already, stored safely away from them we hope!)

But can it really be used to tell if you’re pregnant or not? Well, apparently so! And some of the mums on our forum have been trying it out.

What is the home bleach test?

The basic idea of the test is that if you add your urine to a cup of bleach and it produces a foam – like the pic above and the ones in our forum thread show – you’re pregnant, as NicoleShorney confirms: “Hi, I have found out that if [the bleach] bubbles, foams or fizzes and stays in the cup, you are pregnant!

“If nothing happens and it dissolves you are not pregnant! As the bleach detects the pregnancy hormones and makes a reaction that stays there! Fingers crossed x”

What’s the science behind it?

The general premise is that the hormone hCG, present in your urine only if you’re pregnant, reacts with the bleach to cause a fizz. 

To start with we should say there’s no standardisation of this test – so it’s pretty hard to look at it scientifically. People use different amounts of urine, different amounts of bleach and containers in various materials to carry out the test.

Does it work?

Well, it’s not 100% accurate, that’s for sure. If you take a look on YouTube you’ll find lots of videos of fizzing bleach. Some are from women who already know they’re pregnant, and taking the bleach test has simply confirmed it.

On our very own MFM forum, Susiegirlygirl shared this amazing super-foamy pic – and she is, in fact pregnant.

But while lots of online clips show fizzing bleach, there’s not always an indication accompanying the vid of whether the person doing it has had the results officially stated by a doc or approved pregnancy test.

Why do a bleach test?

Lots of women seem to find it’s just a fun – and different – way to see if they’re pregnant using something they probably already have in the home.

And there just might be some instances when you can’t get hold of a proper pregnancy test.

For example, one of the mums on our team suspected she was pregnant on Christmas Day and there were no shops open near her to buy one. She said if she’d have know about this test she might have given it a go!

Overall though we would say, don’t rely solely on a fizz or foam from bleach to confirm you’re pregnancy, but do invest in a proper, approved test or take a trip to the doc to make it official.
