Progesterone (PdG) Urine Tests Q&A

What is Progesterone? 

Progesterone is a hormone that helps prepare the female body for conception. Progesterone levels in the female body are low in the first half of the menstrual cycle. Once ovulation takes place, the ovaries produce progesterone in significantly higher amounts.

What is Pregnanediol Glucuronide (PdG)?

Pregnanediol Glucuronide (PdG) is the major urine metabolite of Progesterone.

What does the Easy@Home Progesterone (PdG) Urine Test measure?

The Easy@Home Progesterone (PdG) Urine Test detects elevated levels of PdG in urine. A positive result from a PdG test may confirm that ovulation has occurred?

How does the Easy@Home (PdG) Urine Test work?

Levels of Progesterone in the female body will rise after ovulation in regularly ovulating women. Easy@Home Progesterone (PdG) Test Strips measure the presence of PdG in urine, which has been shown to directly correlate with the presence of progesterone in serum (blood). PdG levels in urine typically rise gradually 24-36 hours after ovulation. It may take up to 5 days after the LH Surge to buildup enough PdG to get a positive test result. Once the PdG level exceeds 5000 ng/ml, the test will show a positive result. A positive PdG test result can indicate that ovulation has likely occurred.


When should I use the Easy@Home Progesterone (PdG) Test?

Easy@Home Progesterone (PdG) Test Strips should be performed AFTER you believe ovulation has taken place. It is highly recommended to use PdG Tests 5 days after the positive result achieved with OPK. For details, please refer to the package insert.

How do I use the PdG Test?

Step 1: Dip the strip into the urine for 5 seconds with the arrows pointing towards the urine.

Step 2: Lay the strip flat on a clean surface.

Step 3: Read the results in 3 minutes. 

How are Progesterone (PdG) Urine Tests different than Ovulation Predictor Kits (OPKs)?

Ovulation predictor kits measure a hormone called luteinizing hormone(LH), which is released 24-48 hours before ovulation occurs. Progesterone (PdG) Urine Tests measure the presence of PdG in urine, which is produced after you ovulate. Therefore, ovulation predictor kits (OPKs) are used before ovulation and Progesterone (PdG) Urine Tests are used after ovulation.

Do these tests replace BBT charting?

Yes and no. Both PdG test and BBT may confirm the ovulations, and have their own advantages. Theoretically the release of progesterone after ovulation results in a BBT temperature increase of about .05-1 degree F. Most BBT charting methods require 3 elevated temperatures in a row in order to confirm ovulation has occurred, the PdG Test can indicate ovulation has occurred as early as the first day of elevated temperatures.However, BBT can predict the ovulation day for the next cycle while PdG does not. Even so, the PdG test is much easier to perform, which is a big relief in terms of work, commitment and pressure. Therefore, Progesterone (PdG) Urine Tests can either compliment or replace BBT charting methods.

How many tests do I need per month?

There are several factors that affect the number of tests you will need per month. These factors include: average cycle length, use of ovulation predictor kits (OPKs), BBT charting, cervical mucus (CM), etc. However, the average user will need 1-5 tests per month. Only a single positive test is needed to confirm the presence of elevated progesterone metabolites in the urine.

Do I need to use first morning urine?

The test is most accurate with first morning urine. For best results, only use first morning urine for testing.

What does it mean when the test line is lighter than the control line?

If you see 2 lines, one in the control area and one in the test area, the test is a negative for PdG.

Is my test positive if I see a very faint greyish line in the test line area?

Yes, occasionally there are compounds in the urine that react with the test react with the test line area and create a very slight greyish line. If your test has no pink color in the test line area, it is considered positive.

Does alcohol or medication affect the results?

Yes, hormonal birth control (pills, patches, rings, etc) and any medication containing natural or synthetic progesterone will affect your results.

I have taken these tests as directed and I never get a positive result, what is going on?

If you never get a positive result, you should consult your physician and inform them of this information.

I got a positive result, does that mean I ovulated?

In our research studies, most home users reported positive results 3-6 days after suspected ovulation. Clinically, positive results were observed when serum progesterone was >10ng/ml.

Will the product work if I have PolyCystic Ovarian Syndrome (PCOS)?

Yes. Ovulation predictor kits (OPKs) measure luteinizing hormone (LH). Many women with PCOS have elevated LH and therefore cannot use standard ovulation prediction kits or can have surge, but still not ovulate. However, the Easy@Home Progesterone (PdG) Urine Test indicate the presence of progesterone, which is produced after ovulation in women, including those with PCOS.

Do urine PdG levels always correlate with blood progesterone levels?

For most women, yes, but we have found that 5-7% of women don't metabolize progesterone into PdG at high enough levels to result in a positive PdG test result. If you fail to get a positive PdG test, we recommend tsking PdG tests on any pre-ovulatory day, 5 and 7 days after a positive LH test to determine if your PdG levels have increased.
