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
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
If you're pregnant
Don’t do this test if you're pregnant, as we won't be able to interpret your results.
