Fertility Balance G1 Test Kit (Day 21)
Tests included: Progesterone, Estradiol E2.
Fasting required: Yes, 10 – 12 hours. Testing 30 minutes from wakening recommended.
Why choose this test?
The G1 test is a simpler option to the G2 test [link], giving a snapshot of the key reproductive hormones at work. If you are otherwise healthy, taking this test may just provide that reassurance that all is normal.
What makes these hormones so important?
Progesterone (P4): is vital for conception and maintaining pregnancy. One of the main actions of progesterone is to help support a developing embryo. During pregnancy the placenta produces progesterone to help sustain the developing baby.
Estradiol (E2): is commonly known as the female hormone, and it is one of the most important female reproductive hormones. Estradiol is the the predominant form of estrogen. Having the right balance of estrogen in the body is important to be able to maintain optimal fertility.
When to test?: The only hormone here that comes with strict testing instructions pertaining to date is progesterone. For the majority, but not all women, day 21 of your cycle, (that’s 21 days from the end of the last period not including spotting) is the ideal test date. This Kit comes with specific instructions and chart designed to assist you in determining when to test. Our friendly support team are also standing by to assist.
Important: Don’t bother testing progesterone levels in the pre-ovulation phase (follicular phase) or whilst using birth control. Post menopause, you have very low progesterone so unless you are taking bio identical hormones, testing is unnecessary.

No, it is not necessary to stop taking your supplements.
In men, the reproductive hormones can be measured at any time; however, in women it gets a bit more complicated!
– I have irregular menstrual cycles
It’s OK. Charts used to help you determine the ideal test date are provided with the Fertility Hormone Test Kits.
– I have regular menstrual cycles
The steroid hormones estradiol and progesterone regulate the menstrual cycle and therefore rise and fall at different phases. A typical menstrual cycle completes every 28 days.
Estradiol levels are extremely variable across the course of the menstrual cycle. Estradiol levels are at their lowest during menstruation (day 1-7) and then increase during the remaining follicular phase (8-14 days), peaking just prior to ovulation at day 14. Estradiol levels fall sharply post-ovulation but peak again during the luteal phase around day 21 (at the same time as the rise in progesterone) before declining once more prior to menstruation. Estradiol tests can be performed throughout the cycle but levels should be referenced against established typical ranges for the specific phase of the cycle in which testing was done.
Progesterone levels peak in the luteal phase following ovulation. A progesterone test should be performed at approximately day 21 of the cycle (21 days after the beginning of the last period) to capture peak secretion of this hormone.
Testosterone (and other androgen) levels do not vary much over the menstrual cycle but may increase slightly around ovulation.
The laboratory will not compromise themselves by testing saliva that is past its used by (too viscous). Their only concern is the accuracy of the results and the integrity of the laboratory. So when a sample turns up that has been delayed by Australia Post, and it isn't fit for testing, they have no hesitation in rejecting it, and we start the process over (at no cost to you).
More: The official position of saliva travel time is that saliva samples are good for (up to) 12 days, Despite the guidelines, each sample is assessed for suitability upon arrival prior to testing.

Oh no not today. I'm sorry if you had that impression. The sample is now safely in a controlled environment and testing has commenced. This is a rigid process that does have many steps. There are approximately 12 people working in that process using equipment worth many millions of dollars. It's very technical, and I won't pretend to understand it but this process takes approximately 6 - 10 days depending on how many hormones are being tested, and if melatonin is one of them (takes longer).
Another thing, and I hope I am not boring you here, is that any abnormal result will undergo retesting for the sake of accuracy. This adds a couple of days if required.
The only good news here is that the laboratory we use is obsessed with accuracy, and they don't give a toss' about wait time. We are the ones that stress out about that :-). We want our clients to get results as fast as possible and with this laboratory, we don't have to worry about the quality or integrity of the test, which is the most important thing at the end of the day.
So let's keep our fingers crossed you get these by the end of next week, I'll be keeping watch..
Hope that helps explain things and if there is anything else I'm here to assist.
Kind regards, Michelle
