FAST, ACCURATE AND TRUSTED RESULTS
Fertility relies on a careful balance of hormones that control ovulation, sperm production, and reproductive health. When that balance shifts, it can affect your chances of conceiving or indicate underlying conditions that need attention. A fertility blood test helps you understand your hormone levels and reproductive health so that you can make informed decisions about your next steps.
At One Day Tests, you can check your fertility quickly and confidentially with our specialist range of hormone and reproductive tests. Whether you are planning a pregnancy, undergoing fertility treatment, or simply want reassurance, our tests give you clear, fast results — available in 24 to 48 hours. You can order a home test kit or visit one of our UK clinics for in-person collection.
WHAT IS A FERTILITY BLOOD TEST
A fertility blood test measures the levels of key hormones that affect reproductive health in both men and women. These hormones regulate ovulation, sperm production, and the ability to conceive naturally.
In women, these markers help determine ovarian reserve, ovulation timing, and hormonal causes of fertility issues. In men, they assess testosterone production, and related hormonal function.
Fertility blood tests are suitable for anyone who is trying to conceive, wants to understand their reproductive health, or is preparing for fertility treatment.

WHY TAKE A FERTILITY BLOOD TEST
Understanding your hormone profile is an important first step in assessing fertility. Imbalances can make it harder to conceive or maintain a pregnancy, but early detection allows for the right treatment and lifestyle adjustments.
You may choose a fertility blood test if you:
- Have been trying to conceive without success
- Experience irregular or absent periods
- Have symptoms of polycystic ovary syndrome (PCOS)
- Are planning IVF or fertility treatment
- Want to check fertility before starting a family
- Have concerns about sperm health or hormone levels
Both men and women can benefit from fertility testing, especially when trying to identify hormonal causes of fertility difficulties.

UNDERSTANDING YOUR RESULTS AND NEXT STEPS
Your results show your hormone levels and how they compare to the expected ranges for your age and gender. This helps identify any imbalance or condition that may affect fertility.
If your results suggest issues such as low ovarian reserve, irregular ovulation, or abnormal testosterone, further investigation may be recommended. You can share your results with your GP or fertility specialist to discuss the best course of action.
Many people choose to retest over time to track hormonal patterns and progress, particularly during fertility treatments or after lifestyle changes.
FREQUENTLY ASKED QUESTIONS
What blood tests are done for fertility?
Common fertility blood tests include FSH, LH, oestradiol, progesterone, AMH, testosterone, and prolactin. These hormones help determine whether ovulation is occurring and whether hormone levels support conception.
Can my GP order an AMH test?
Some GPs can arrange an AMH test, but this varies by region. AMH testing is often limited through the NHS and usually offered as part of specialist fertility care. Private testing provides faster access and wider availability.
Can your GP give you a fertility test?
GPs can order basic fertility blood tests such as FSH, LH, and progesterone. However, more advanced profiles, including AMH and full hormone panels, are usually available through private testing.
Can I get an AMH test on the NHS?
he NHS may offer AMH testing if you are referred to a fertility clinic, but it is not routinely provided as part of general practice. Private testing through One Day Tests gives you quick access to AMH and other fertility markers without waiting for a referral.
