The world’s first saliva pregnancy test is now available. The new test is called the SaliStick and is available in stores in the United Kingdom and Ireland. It works the same way as the oral COVID-19 tests. A hand-held applicator is used to collect a saliva sample, which is placed in the analysis unit. Results are displayed on the screen after 10 minutes. Two lines indicate pregnancy and one line indicates a negative test result.
The SaliStick checks for elevated levels of β-HCG, known as the pregnancy hormone, which is usually detected in saliva after about three to four weeks and steadily increases. In clinical trials involving more than 300 women, the test has proven to be about 95% accurate when performed from the first day of menstrual delay.
The advantage of the test is that you don’t have to find a bathroom, and you don’t have to accidentally urinate on your hand while trying to pass the test with a urine stick. However, you must wait 30 minutes after eating or drinking to take the test.
“This exciting innovation offers women the ability to test for pregnancy in a cleaner, easier and simpler way and is a long-awaited development in the pregnancy testing market,” said Chris Yates, CEO of Abingdon Health, which partners with the company behind SaliStick, the Israeli saliva testing startup Salignostics.
Salignostics has been developing a range of saliva tests since its inception in 2016. It has applied for FDA approval to sell the product in the United States. The company has expanded its production to be able to produce one million tests a month.
SaliStick is sold exclusively in Superdrug stores for £9.99 ($12.75), which is comparable to traditional pregnancy tests on the market.
This innovation in the world of pregnancy testing can be helpful for women who want a quick and hassle-free test. However, like any other test, the SaliStick is not completely accurate and can give false positive or false negative results.
