At home ovulation kit is based on a saliva sample to help women track fertility

After an unexpected pregnancy almost killed Helen Denise, the New Jersey-based woman came up with a plan to help other women avoid a similar situation, while also at those who were trying to get pregnant: a house and ovulation test kit that uses saliva instead of urine.

Denise, CEO of HiLin Life Products and the creator of KNOWHEN, said that when she was 40, she was under the impression that she was not pregnant. As a result, she was having unprotected sex with her partner, which ended in an ectopic pregnancy. The experience left her shaken and determined to help other women better understand their bodies and fertility cycles.

“Women need to their body,” said Denise “Many women have no idea about the mystery of the ovulation, [but] simple if you know what’s going on.”

The reusable kit, which is FDA-certified and boasts a 98.9 percent accuracy, the five most fertile days of a woman’s cycle by detecting the level of hormones in the saliva. Dr. Kecia Gaither, a double-board-certified OB-GYN who does not work on the development of KNOWHEN, told that saliva is more accurate than a urine sample because the results are not subject to any other substances, such as alcohol.

When a woman is ovulating and levels of estrogen are raised, the saliva is more salt in the composition. Use of the test, the user puts a drop of saliva on the kit mini-ovulation microscope lens immediately after they wake up—for brushing her teeth or drinking coffee.

Users can interpret their results by looking at the kind of pattern left on the lens by the dried saliva. Women who do not ovulate and are at the least fertile point in their cycle, see a smudge on the lens, while those who are almost at the beginning or the end of their ovulation period of time will observe a few fern-like patterns. Women who ovulate will observe defined fern-like patterns on the lens, the signals from their most fertile period for the best chance of conceiving a child.

Faith Kirkpatrick, who was in her early 30s, when she and her husband decided to start their family, received the kit after a discussion with her mother. Kirkpatrick wasn’t sure whether she would have trouble thinking before they started trying. They used the kit for the first and the second month and said the results were fairly accurate and easy to read, but she wasn’t regularly have to respond.

“The following month, I was like, ‘OK, we really want it to happen,'” Kirkpatrick, who lives in Westchester, New York, told “We tried the whole week, every other day, and that was the month we got pregnant.”

Kirkpatrick said the kit helped to relieve much of the stress that she witnessed a number of her friends who are unable to keep track of their cycle to go through. Their daughter is now 2 and Kirkpatrick, 36, said she’s ready to start using the kit again to plan their next pregnancy.

While Gaither, who lives in New York and works in a perinatal consulting at St. Luke’s Medical Center in Kansas City, Missouri, said that while the test is quick and simple in-home tool, it should not be in the place of medical care if a woman has an underlying problems. She noted that the results may be distorted for women who are obese, have been diagnosed with polycystic ovary syndrome (PCOS), have recently stopped the use of oral contraceptives, or are taking additional estrogen.

Denise said that she is thrilled that her product has helped women-including her own daughter — is pregnant, but added that it’s also beneficial for women who are trying to prevent pregnancy or to determine whether she experiences menopause. The kit is available online and currently sells for $49.99. It is scheduled to hit the store shelves in early 2017 and includes a free mobile app, so that women can log results and the check of the cycle by means of a simple calendar.

“I feel like I’m on a mission,” Denise said.
