Fertility Blood Tests: LH and FSH Package

For day 2 - 5 of your cycle

This LH and FSH led fertility blood test package is designed to help you get all the information you need during your fertility journey.

This package is ideal for people undergoing fertility treatment with the NHS, as it includes testing Luteinising Hormone and Follicle Stimulating Hormone to assess ovarian reserve (which are the preferred hormones for NHS treatment).


This package includes:

LH is linked to ovarian hormone production and egg maturation. A luteinising hormone test performed at the beginning of your cycle may help diagnose hormonal imbalances, like polycystic ovary syndrome. When LH testing is performed midway through your menstrual cycle (day 14 of a 28-day cycle), the level may assist in determining when you’re ovulating.

In men, LH stimulates the hormone testosterone which affects sperm production. An LH test may be useful in evaluating male-factor infertility.

FSH helps control the menstrual cycle and the growth of follicles, which contain eggs, in the ovaries. The blood test is done on the second or third day of your menstrual cycle and is used to evaluate egg supply and ovarian function.
In men, FSH regulates the production and transportation of sperm. The test is used to determine sperm count.

A Full Blood Count blood test provides details about your iron levels. Research has shown that iron deficiency can be linked to infertility, as iron can directly impact ovulation and oxygen levels that contribute to egg quality. Your fertility provider can make decisions about your treatment based on your iron levels.

Prolactin is a hormone produced by the pituitary gland. Testing prolactin levels can help evaluate infertility and determine why a woman is not ovulating.

The Thyroid T3 Blood Test measures the amount of T3 in your blood, which can indicate whether your thyroid is functioning normally or not. Healthy thyroid function is important for reproductive health in women and mean.

The Thyroid T4 Blood Test measures the amount of T4 in your blood, which can indicate whether your thyroid is functioning normally or not. Healthy thyroid function is important for reproductive health in women and mean.

Testing TSH is a vital part of fertility treatment, as TSH can affect how you respond to treatment. The functioning of the thyroid needs to be managed during and following fertility treatment as both low and high TSH levels can impact pregnancy. Healthy thyroid function is important for reproductive health in women and mean.

Testing Vitamin D before fertility treatment can provide your fertility provider with a baseline level to ensure that your levels are within a normal range. It will enable your clinician the opportunity to advise you of treatment for a deficiency if required at an early stage in your fertility journey.
Having a good level of vitamin D can have a positive impact on female fertility and pregnancy. Having higher levels of vitamin D can also improve symptoms of polycystic ovary syndrome (PCOS) and endometriosis, which are both common conditions that affect female fertility.

When will I receive my blood test results?

The time in which you receive blood test results will vary based on your location and the type of blood test. We have courier services available at some clinics which can provide results in 1 - 2 working days. Some lab tests take longer, with results available in 7 working days. You can call your clinic to find out the most likely timeline for your results.

If you book multiple blood tests or a blood test package you may receive the results for each blood test at different times.

Our phlebotomy-trained professionals will take a blood sample from you. This sample will be analysed in the UK by our authorised partners, TDL.

Preparing for your fertility blood test appointment

    Wear loose clothing that allows easy access to both arms and hands.

  • If you are on anticoagulant medication, take it after the appointment

    If this is not possible, you can take it before your appointment, if it is absolutely essential.

    They will make sure you’re calm and comfortable and do everything they can to make your blood draw quick and simple.

Frequently Asked Questions

No, we will send you the results and recommend that you share these with your GP or fertility provider.

It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site.  If this causes you concern, check with your practice nurse. 

Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
