How to Check Your Hormone Levels in Australia

How to check your hormones in Australia

Checking your hormones used to mean booking a GP appointment, hoping your symptoms were enough to have a test ordered, waiting for the referral, then booking a second appointment to discuss the results. MediTests removes all of that. You choose the panel that matches your symptoms, order online, and receive your pathology referral instantly by email. There is no consult, no clinical justification required, and no waiting room.

From there it is simple: walk into any of 3,300+ collection centres across Australia at a time that suits you, and your results land in your inbox, typically within 24 to 48 hours, reviewed by AHPRA-registered doctors. You can then take those results to your GP or specialist for interpretation, which is exactly what we recommend. It is the most direct way to get a clear read on your hormones, on your own terms.

How private hormone testing works, step by step

1. Choose your test. Pick the panel that fits your symptoms and goals from the hormone tests page. Not sure? See the guide below.
2. Order online. Checkout takes a couple of minutes and you receive a PDF pathology referral by email straight away.
3. Walk into a collection centre. Take your referral to any of 3,300+ centres across Australia. No appointment needed. Turn up when it suits you, ideally in the morning for testosterone.
4. Get your results. Your full report lands in your inbox, typically within 24 to 48 hours, with every marker shown against its reference range and reviewed by AHPRA-registered doctors.

Which hormones should you check?

The right markers depend on who you are and what you are noticing. Here is a simple guide, and each links to the panel that covers it.

You can browse everything by audience under men's health and women's health.

What each hormone tells you

A quick reference for reading your own report. Each hormone is interpreted alongside the others, not in isolation.

• Testosterone (total and free): drives energy, libido, strength and mood. Low free testosterone is the more telling result in men; raised levels in women can point to PCOS.
• SHBG: the binding protein that controls how much testosterone and oestrogen is active. High SHBG lowers your active hormone, low SHBG raises it.
• Oestradiol: the main oestrogen. In women it swings across the cycle, so timing is everything. In men, a raised level often accompanies low testosterone.
• Progesterone: rises after ovulation. Low progesterone relative to oestrogen is linked to PMS, heavy periods, anxiety and poor sleep.
• FSH and LH: pituitary signals. A rising FSH in women is a key sign of the menopause transition; the LH to FSH ratio helps flag PCOS.
• Prolactin: a raised level in either sex can suppress other hormones and cause low libido or cycle changes.
• Cortisol: your stress hormone, highest in the morning. Chronically high or blunted patterns affect energy, sleep and weight.
• Thyroid (TSH, Free T3, Free T4): sets your metabolic rate. Often the real driver behind fatigue, weight and mood symptoms.

When to test: timing matters for women

Most male hormones can be measured on any day, ideally in the morning between 7am and 10am when testosterone peaks. For women, reproductive hormones shift through the cycle, so timing changes the result. The menstrual cycle has two halves: the follicular phase (from your period to ovulation) and the luteal phase (from ovulation to your next period). The general guidance from Jean Hailes for Women's Health is:

• Days 2 to 5 (early follicular): FSH, LH and baseline oestradiol. This is when the pituitary signals are cleanest to read.
• Around day 21 (mid-luteal, or 7 days before your period): progesterone, to confirm ovulation has occurred.
• Any day: testosterone, SHBG, prolactin, cortisol, DHEAS, AMH and thyroid hormones.

If you are on hormonal contraception, your natural cycle is suppressed, so reproductive hormone results reflect the medication rather than your own pattern. For a true read, testing 6 weeks or more after stopping is more informative. If your cycles are irregular, testing progesterone by "day 21" is tricky, so discuss timing with your doctor.

How to prepare for your test

• Time of day: test in the morning where possible, especially for testosterone and cortisol.
• Fasting: most hormone tests do not require fasting. If your panel includes glucose, insulin or lipids, fast overnight for 8 to 10 hours. Water is fine.
• Biotin: high-dose biotin or B-vitamin supplements can interfere with hormone immunoassays, so it is generally suggested to pause them for around 48 hours before testing.
• Illness and stress: acute illness and short-term stress can shift results, so test when you are well and settled where you can.
• Medications: some medications affect hormone levels or the test itself, so mention anything you take to your doctor when interpreting results.

How to read your results

Your report shows each hormone against a reference range. A result outside the range is a prompt for a conversation, not a diagnosis on its own, because hormones are interpreted together and alongside your symptoms, age and cycle. Reference ranges also vary between laboratories and assays, and for women they depend heavily on the cycle day, so the same number can mean different things at different points in the month.

Two things are often more revealing than any single marker. The first is a ratio, such as oestrogen relative to progesterone, or LH relative to FSH. The second is a binding protein, since SHBG can make a normal-looking total testosterone misleading. This is exactly why a full panel beats a single test, and why a "normal" result can still sit next to a meaningful imbalance. Take anything unexpected to your GP or specialist, who can interpret it in the context of your history.

Testing on the pill or HRT

Hormonal contraception and hormone therapy change what your results mean. The combined pill suppresses your natural cycle and can lower measured free testosterone by raising SHBG, so reproductive hormone results reflect the medication, not your baseline. If you want to see your own natural levels, testing several weeks after stopping is more informative. On HRT or TRT, testing is about monitoring rather than diagnosis, and should follow your prescriber's protocol on timing relative to your dose.

How often should you retest?

For general wellbeing or symptom investigation, every 6 to 12 months is reasonable. If you are actively making lifestyle changes, retest at around 3 months to see the impact. On TRT or HRT, follow your prescriber's protocol, typically every 3 to 6 months. Testing at a consistent time of day and cycle point keeps your results comparable over time, which is what makes tracking useful.

Common mistakes to avoid

• Testing testosterone in the afternoon. Levels fall through the day, so a late sample can read falsely low.
• Ignoring cycle timing. A progesterone test on the wrong day can look "low" simply because you had not yet ovulated.
• Testing only one marker. A single hormone rarely tells the story; ratios and binding proteins matter.
• Forgetting biotin. High-dose supplements can distort results.
• Reading results without context. Numbers mean little without your symptoms, age and history, so loop in your doctor.
