If you’ve spent any time on TikTok, you’ve probably seen viral hacks claiming to make pregnancy tests more accurate, detect pregnancy earlier, or even "retest" old tests. But do these hacks actually work? Let’s break down some of the most popular ones (and what science has to say about them).
1. The Water Dilution Hack
One viral TikTok trend suggests that if you get a faint positive on a pregnancy test, you should dilute your urine with water and test again. The idea is that high hCG levels (the pregnancy hormone) can sometimes cause a "hook effect," leading to false negatives.
The Truth: The hook effect is rare and usually only occurs much later in pregnancy when hCG levels are extremely high. For most people testing early on, diluting urine will only make the test less accurate.
2. Using an Old Pregnancy Test to “Recheck” a Result
Some TikTok users claim you can add water or urine to an old test to reactivate it and get a second reading.
The Truth: Pregnancy tests are single-use and designed for a one-time reaction. Once the test has dried, it cannot be reused. Any lines that appear afterward are usually evaporation lines, which don’t indicate pregnancy.
3. Bleach, Sugar, or Toothpaste as DIY Pregnancy Tests
These hacks claim that mixing urine with household products like bleach, sugar, or toothpaste can reveal pregnancy based on fizzing, clumping, or colour changes.
The Truth: These DIY tests are not scientifically valid. The only reliable way to detect pregnancy is with an hCG-based test (like Ovry’s early detection tests) or a blood test from your doctor.
What Actually Works?
If you’re trying to get the most accurate pregnancy test result, here’s what you should do:
✔ Use an early detection test if testing before your missed period.
✔ Test with your first pee of the day for the highest concentration of hCG.
✔ Follow the instructions on your test carefully - no TikTok hacks needed!
The Bottom Line
TikTok can be a fun source of information, but when it comes to pregnancy testing, it’s always best to rely on science, not social media trends. Stick to clinically tested pregnancy tests, and if you're ever unsure, consult a trusted healthcare provider.
