What tests do you offer?

We currently offer PCOS and post-birth tests.

Our women's health tests can help give you insights into your hormonal health.


What can the PCOS test tell me?

Our PCOS package can help you understand if symptoms like irregular periods, acne, difficulty getting pregnant, or excess body hair might be caused by polycystic ovary syndrome (PCOS).

If you have PCOS, this test can also help you monitor:

  • manage your symptoms

  • lower your risk of longer-term issues associated with PCOS — like high blood sugar levels


What can the post-birth test tell me?

Our post-birth package is for those who'ave recently (within the last year) had a baby and/or are breastfeeding and want to make sure they are getting the right nutrients.

During pregnancy, your body requires a higher amount of certain nutrients — like vitamin D and folate. Plus, blood loss from birth can sometimes cause a drop in your iron levels. And if you're breastfeeding, your requirements for certain nutrients also increase.


What day should I do my women's health tests on?

For PCOS tests, the best time to take your blood sample is on day 3 of your period — this is the best time to accurately interpret your results. You can also do your test on days 2-5 of your period but we really recommend trying to do it on day 3.

And for the post birth-package, you can take this any day but it's best to wait until 6-8 weeks after birth to do this test.

What happens if day 3 falls on a weekend?

If day 3 falls on the weekend, you should do your test on the Friday or Monday — as long as it falls between days 2-5 of your period.


I have a question about my period.

  • Can I do a test if I don’t have a period (amenorrhoea)?

You can do this test at any time, but it might be harder for our doctors to interpret your results.

  • When should I take the women's health test if my periods are irregular?

We advise you to take the test on days 2-5 of your cycle with day 3 being most optimal. Day 1 is the first day you bleed on your period; the following day is day 2 of your cycle. If your periods are irregular, this can be tricky. But if you do bleed, take the test on the day after you start bleeding.

  • Can I do a test if I’m taking the pill?

The combined contraceptive pill (containing both oestrogen and progesterone) works by reducing your FSH and LH levels — reducing your natural oestrogen, progesterone and possibly your testosterone levels. So taking this test while on the pill will only tell what effect the pill is having on your hormone levels, not your natural hormone levels.

But if you did still want to do the test, just add what type of contraception you're on in your health profile so the doctor can take it into account when writing your report.

  • Can I do a test if I’m using any form of contraception?

Any form of contraception which involves hormones like the pill, patch, ring, injection, hormonal coil, and implant can affect your test results.

Hormonal contraception interferes with naturally produced hormone levels, so your results will be less useful.

  • I've recently stopped hormonal contraception, when can I do the test?

We recommend waiting 3 months before doing this test — this allows time for your natural cycle to return. This includes the oral contraceptive pill, patch, ring, hormonal coil, implant, and hormone replacement therapy (HRT).

If you were using the contraceptive injection, we recommend waiting a year.

  • I've taken emergency contraception, when should I do the test?

To be on the safe side, we advise that you wait until after you’ve had a normal period post-emergency contraception and then complete the test to be sure of the accuracy of your results.

  • Can I do a test if I’m pregnant?

No, we don’t recommend doing a test if you’re pregnant. This is because your hormone levels change significantly in pregnancy so we can’t correctly interpret your results during this time.

  • Can I do these tests if I'm breastfeeding?

Breastfeeding can affect your hormone levels — which can make it difficult to accurately interpret your results. We would recommend waiting until you've stopped breastfeeding and have had a period, then testing on your next cycle.

Except for the post-birth test, you can take this test while breastfeeding.

  • I've recently had a miscarriage, when's the best time to do the test?

We’d recommend waiting until your periods have returned to normal and take the test on your second normal cycle.

  • Can you help recommend what test is right for me?

Unfortunately, as much as we'd love to help you, we can't advise specific tests based on conditions or symptoms.

Here at Thriva, we are passionate about helping our customers to live healthier for longer. But we are not a diagnostic service, and so we are unable to offer individual clinical advice.

The recommendations that our "build your own package" produces are based on general healthcare and lifestyle guidance.

If you feel you might have a specific testing requirement because of a condition or symptoms, we'd recommend speaking to your GP first. Because they'll best understand your medical history.


Why do I need to fill in the women’s health questionnaire?

This is important as it gives more context to help the reporting doctor write your personalised report.

It helps them to understand whether symptoms like irregular periods are related to your hormone results or whether they can offer helpful advice for your selected life stage, such as trying to conceive.


Why are the hormone ranges different to other ranges I have seen?

Different labs have different reference ranges depending on what way the tests are analysed. This is why you might find different reference ranges online or through your GP/practitioner.


What if I get an abnormal test result?

We’re not a diagnostic service so we always recommend discussing your test results with your GP or practitioner if they’re abnormal or if you've any symptoms.
