Frequently Asked Questions
Let us help you Proov!
We’ve provided answers to common questions below, but if something still isn’t clear, please reach out — firstname.lastname@example.org.
What does Proov measure?
Proov tests measure the urine metabolite of the hormone progesterone called Pregnanediol Glucuronide, or PdG for short.
When is progesterone produced?
What exactly is Progesterone?
Why should I test my Progesterone levels?
How are Proov tests different from ovulation predictor kits (OPKs)?
Ovulation predictor kits typically measure a hormone called luteinizing hormone (LH), which is released 24-48 hours before ovulation occurs. Proov tests measure a metabolite of progesterone, which is produced after you ovulate. Therefore, OPKs help to predict when ovulation will occur and Proov tests allow women to confirm that ovulation has occurred.
How are the tests packaged and when do they expire?
How accurate are Proov Tests?
In lab studies, Proov tests were 99% accurate for detecting Pregnanediol Glucuronide (PdG) in urine.
Are Proov tests clinically validated?
Do Proov tests meet FDA requirements?
Yes, Proov tests are FDA compliant. The tests are manufactured in an FDA inspected and certified facility under cGMP conditions. Each batch of tests meet all required specifications before being sent to consumers.
Are Proov tests quantitative?
Why is a single line a positive result and two lines are a negative result?
Ovulation Predictor Kits (LH) and HCG pregnancy tests work by sandwiching the hormone between two antibodies. As such, a second line indicates a positive test for LH and HCG tests. Since the metabolite of progesterone is so small, this same technique does not work for Proov tests. Instead, we use a different method that indicates a positive test via 1 line instead of 2. Similar methods are used to measure estrogen and detect drugs in urine.
The test line is lighter than the control line. What does that mean?
When do Proov tests typically turn positive?
Proov tests turn positive anywhere between 2-7 days after ovulation and remain positive until 1-3 days before the next menstrual period or if conception has occurred, will remain positive through the pregnancy.
I still see a very faint, greyish line in the test area. Is my test positive?
Do alcohol or medications affect the results?
Alcohol does not affect your results. However, hormonal birth control and medications containing natural or synthetic progesterone will affect your results.
I have taken these tests as directed and I never get a positive result. Do I have low progesterone?
Proov tests do not replace medical advice. If you never get a positive result, you should consult your physician and inform them of your results so they can properly diagnose you.
Do Proov tests work to detect progesterone for everyone?
Proov tests work for most women. However, our studies show that 7-12% of women do not metabolize progesterone into PdG at high enough levels to get a positive Proov test result. While these women may show sufficient progesterone levels via a blood test, Proov tests will not turn positive. If you suspect that you may be in this group of women, please contact us at email@example.com.
I am unsure of my test results. Can you help?
How many Proov tests do I need per month?
Where are Proov tests sold?
Proov tests can be purchased via our website or on Amazon.
I live in Europe. Can I get a Proov test kit?
Unfortunately, no. Proov tests are currently only available for shipping to the United States, Canada, and Australia. Please contact us if you are interested in discussing distribution opportunities in your country: firstname.lastname@example.org.
