Estrogens & all metabolites | Progesterones | Androgens | Testosterones | BPA |

This test is great for 18+ yr old women who would like to start measuring and tracking their sex hormones and estrogen metabolites. 

Even though this test measures the main sex hormones, its focus is estrogen and estrogen metabolites. We love that this test includes BPA - an environmental xenoestrogen.

Knowing your estrogen metabolites, alongside your hormones, is highly valuable in lifestyle-related chronic disease prevention, especially estrogen-positive breast cancers. 

While we believe you should always try and buy a test that will give you as much info as possible about your body, this test is also a great option if you're on a budget.

This test is done through one of the most niche, accurate and highly-specialised hormone labs in the world. We love that the lab's founder, Dr David Zava, has been a research leader in hormonal imbalances, estrogen-related disorders, estrogen cancers, and hormonal breast cancers for over 40 years.

          Why is estrogen important?

          Many man-made chemicals have been shown to have an estrogen-like effect in your body. They are called xenoestrogens; 'xeno' meaning 'from the outside' or 'foreign'. It's sad, but our planet is estrogen-ising!

          As more of these chemicals enter our environment daily, it's hard to avoid exposure. These chemicals build up in our bodies and can contribute to estrogen excess and estrogen dominance (over progesterone). 

          The number of new cases of hormone cancers, estrogen cancers, hormone cancers at younger ages, and hormone cancers with no family history, is at an all-time high. Most breast cancer cases are estrogen-positive, then progesterone.

          Only 5-10% of breast cancers are due to the BRCA (Breast Cancer) 1 & 2 gene mutation.

          Research shows that the other 70-80% of breast cancer cases are due to the interaction between our nutrition, environment and lifestyle choices and our genes. This interaction can cause, among other things, estrogen excess, estrogen dominance (over progesterone), oxidative stress, inflammation, and the production of harmful hormone metabolites.

          Of this 70-80%, most of these breast cancers are estrogen positive - meaning their growth is driven by estrogen. 

          Breast cancer is the second most prevalent female cancer. Half the world’s population is female. We really need to start preventing breast cancer earlier, using methods other than/in addition to just traditional scans like ultrasounds, mammograms and MRI's.

          Why are estrogen metabolites important?

          Doing this test allows you to measure your estrogen levels, your estrogen:progesterone ratio, and your estrogen metabolite ratios.

          As your hormones are broken down, they form breakdown products called 'hormone metabolites'. Some hormone metabolites are safe and can protect against cancer. Other hormone metabolites are dangerous because they can damage DNA and, over time, potentially initiate cancer. 

          An estrogen metabolite called 4-hydroxy estradiol is capable of causing the most damage to DNA. It is vital that this metabolite is measured, tracked, kept within safe levels and neutralised as much as possible.

          Specific nutrition, environment and lifestyle choices can help neutralise this metabolite. Pair this test with our DNA | Estrogen test to further personalise your choices.  

          Symptoms of estrogen excess & dominance 

          'Estrogen excess' is when you have a normal progesterone level but a raised estrogen level.

          'Estrogen dominance' is when you have more estrogen than progesterone. You might have normal estrogen but low progesterone due to, for example, stress or skipping/lack of ovulation.

          Estrogen dominance has also been linked to allergies, autoimmune disorders, breast cancer, uterine cancer, infertility, ovarian cysts, and increased blood clotting, and is also associated with acceleration of the ageing process.

          Estrogen excess and dominance can be caused or exacerbated by the stress of all kinds.

          Many women in their thirties and early forties find that they experience moderate to severe symptoms of estrogen dominance as they approach perimenopause.

          The symptoms listed below, as well as many others, often arise when estrogen overstimulates both the brain and body:

          • Irregular or otherwise abnormal menstrual periods
          • Bloating (water retention)
          • Breast swelling and tenderness
          • Decreased sex drive
          • Fibrocystic breasts
          • Headaches (especially premenstrually)
          • Mood swings (most often irritability and depression)
          • PMS
          • Weight and/or fat gain (particularly around the abdomen and hips)
          • Thyroid dysfunction
          • Cold hands and feet (a symptom of thyroid dysfunction)
          • Hair loss
          • Sluggish metabolism
          • Foggy thinking, memory loss
          • Fatigue
          • Trouble sleeping/insomnia

          Why can this test be preventative?

          This test doesn’t look for cancer markers in your blood - by then, you already have cancer. It shows imbalances in your estrogen detox biochemistry long before you start might start experiencing signs of estrogen excess, estrogen dominance, or detect an estrogen cancer. 

          These imbalances can start when you're young and only ‘tip’ into cancer when you're older (as we learnt the hard way!). That's why this test is so useful - it allows you to see your biochemistry while there's still time to correct biochemical imbalances. 

          Almost everyone knows someone with cancer, someone who has had cancer, or someone who has died from cancer. We believe that, in today’s world, so many of us are estrogen dominant, or have hormone imbalances, without even knowing.

          Today, there’s so much we can do to detect imbalances early. Based on your test results, you can make more personalise nutrition, environment, and lifestyle choices to better feed, protect, and nurture your DNA hopefully long before you develop symptoms of estrogen excess or an estrogen cancer. Detecting a hormone-driven cancer on a breast, ovarian, or uterine scan might be too late. 

            Who would benefit from this test?

            Anyone with 1 or more of the following:

            • Hormonal imbalances resulting in symptoms and signs of estrogen excess and/or dominance (see list above)
            • Stress, acute or long-term
            • Battling to sleep and you think it might be due to too much stress
            • Signs of estrogen excess or estrogen dominance
            • Considering hormone replacement therapy
            • At-risk of hormone-dependent cancers like breast cancer or prostate cancer 
            • have a risk of hormone-dependent cancers are considering hormone replacement therapy
            • Symptoms of Polycystic Ovarian Syndrome (PCOS)
            • Certain men* might find this test useful - if they have genetic variations that hamper estrogen detox or they are/have been exposed to xenoestrogens in their food and environment. In males, common signs of excess estrogen or problems with estrogen detox include 'moobs' (male boobs), infertility, prostate cancer, and even breast cancer.

              *Men have female hormones, just in smaller amounts. Women have male hormones, just in smaller amounts. 

            More Info



            “We wish this test had been available from when we were 18 yrs onwards. We believe that knowing our estrogen levels, estrogen:progesterone ratios, and our estrogen metabolites, and then taking action to bring these into balance may have prevented our estrogen-positive cancers. 

            We love that this test measures for possible BPA levels in your body. BPA is a xenoestrogen found in plastic water bottles and polystyrene (think junk food packaging) and can contribute to estrogen excess or estrogen dominance (over progesterone).

            There are things that can be done at every level, from lowering the estrogen burden (better diet, exercise, nutritional supplements, better sleep patterns, etc.) to reducing bad 4-catechol estrogen formation (avoiding pesticides, petrochemicals, etc.), to increasing progesterone if not well balanced with estrogens, to increasing androgens if low (i.e. supplementation with DHEA or testosterone), to using cortisol-lowering vitamins, herbs and melatonin to create balance. There are lots of things that can be done to break the hormonal imbalances we often see in breast cancer patients. One just needs to know what these imbalances are, and this urine test is a best logical approach to finding out what’s “off” and what to do about it. Of course, it would be best to know this info long before a breast cancer diagnosis. This is where prevention really lies".

                  Estrogen and its metabolites

                  • This is more 4-Hydroxy metabolites than any other lab (these are the DNA-damaging estrogen metabolites - you need to know their levels and whether or not you need to take steps to neutralise them).


                  • Bisphenol A is, among other things, a xenoestrogen. It has been linked to estrogen excess, estrogen dominance, estrogen-positive cancers, and brain, behaviour and health concerns in children and adults. Our lab is one of few labs to include an assessment of BPA in its urine hormone testing.


                  • Progesterone needs to be in balance with estrogen to avoid estrogen dominance. Estrogen dominance has been linked to estrogen receptor-positive cancers. Low progesterone can also result after acute or prolong periods of stress. 

                  Androgens and testosterones:

                  • Raised male hormones can convert to estrogen and result in estrogen excess or dominance. Raised male hormones are also involved if you have Polycystic Ovarian Syndrome (PCOS).

                        Test sample type

                        • Dried urine - dried urine is a form of collection where you saturate a filter card with a urine sample. 

                            Benefits of dried urine testing

                            • Dried urine testing is the best way to measure adrenal and sex steroid hormone by-products and their respective metabolic pathways, providing a gauge for understanding the body’s hormone metabolism
                            • Dried urine method offers a discreet, at-home testing alternative and eliminates the hassles of all-day jug urine collection
                            • You can collect urine on a filter strip up to four times during the day
                            • Dried strips are shelf-stable for 30 days and easy to mail back to the lab for analysis
                            • Once dry, urine cards are extremely stable for shipment and storage
                            • You don’t need to stop hormone supplementation for this test. Our lab has adjusted ranges for age, menstrual status and supplementation types.
                            • This test is the ideal method for tracking the effectiveness of hormone treatments
