Oestradiol (E2) is a type of oestrogen and is the main female sex hormone. If your E2 levels are too high or low it can cause irregular periods, hot flashes, fatigue, headaches, sleep problems, anxiety, depression, and a low sex drive.

Mid-cycle, your LH levels increase so you can ovulate. If your LH levels are imbalanced, you might have irregular periods and have trouble getting pregnant. High LH levels can indicate menopause or PCOS.

FSH plays a key role in egg production and ovulation. Your FSH levels naturally increase as you age — high levels can be a sign of menopause. If your FSH levels are too high or low you might have trouble getting pregnant.

Testosterone is essential for your sex drive, bone and muscle health, mood, and cognitive function. Your levels gradually drop as you age. If your levels are out of range you might feel tired, have a low sex drive, and have low mood.

An overactive thyroid or underactive thyroid causes hormonal imbalances that can cause symptoms like weight gain or loss, tiredness, low mood, anxiety, depression, and sleep difficulties.
The best time to do this test is on day 3 of your cycle (day 1 is your first day of bleeding) — this is when your results can be accurately interpreted.
If you have irregular periods
We recommend waiting until you have a period to get the most useful insights from this test.
If you have irregular periods combined with symptoms like acne, excess body hair (hirsutism), or weight gain, our PCOS blood test might give you better insights.
If you have no periods
You can do this test anytime, but it might be harder for our doctors to interpret your results.
I wanted to work out what was working for me hormonally and what was not, and most importantly no longer be in the dark on my hormones! I really needed to find out where I might need extra support in my fertility journey.

When should you do this blood test?
You should aim to do this test on day 3 of your period. This is when your reproductive hormone levels are easiest to interpret, giving you the best insights into your cycle.
If you don't have periods
It might be harder for our doctors to interpret your follicle-stimulating hormone (FSH), luteinising hormone (LH), and oestrogen results.
If you have irregular periods
We recommend waiting until you have a period to get the most valuable insights from this test. Test on day 3 of your next cycle.
If you take hormonal contraception
Your results might be harder to interpret if you take the contraceptive pill, injections, or have an implant. This doesn’t apply to the hormonal coil.
If you've just stopped hormonal contraception
Wait 3 months before doing this test — this allows time for your natural cycle to return. If you were using the contraceptive injection, we recommended waiting a year.
If you use oestrogen or testosterone creams/gels
If you use a topical oestrogen-containing or testosterone-containing cream or gel, always use a glove when applying it. Contact with your fingers could affect your finger-prick oestrogen or testosterone result.
If you're breastfeeding
Breastfeeding can affect your hormone levels — which can make it difficult to accurately interpret your results. We recommend waiting until you've stopped breastfeeding before doing this test.
If you're pregnant
Don’t do this test if you're pregnant, as we won't be able to interpret your results.
