At home female fertility blood test
Home Female Fertility Test Kit UK | AMH & Ovarian Reserve
A 7 biomarker home blood test combining AMH ovarian reserve information with LH, FSH, progesterone and androgen markers.
The test provides laboratory information about ovarian reserve, pituitary and ovarian hormone patterns, correctly timed ovulation context and selected androgen markers. Cycle day is recorded so changing reproductive hormones can be considered against the appropriate cycle stage.
This is a hormone and ovarian reserve blood test, not a complete fertility assessment. It cannot diagnose infertility, confirm that you will conceive naturally, measure egg quality, check the fallopian tubes, assess the womb or predict the exact timing of menopause.
Quality and compliance
Home testing supported by UK clinical standards
What the test measures
| Health area | Biomarkers | What they may help show |
|---|---|---|
| Ovarian reserve | AMH | An estimate of the remaining follicle pool and likely response to ovarian stimulation. |
| Pituitary and ovarian signalling | LH and FSH | Cycle stage dependent patterns involving pituitary signals and ovarian response. |
| Ovulation context | Progesterone | Evidence consistent with recent ovulation when collected at the correct point in the cycle. |
| Androgen context | Total testosterone, SHBG and FAI | Selected information about total testosterone, hormone binding and estimated androgen availability. |
Who may consider this test?
This panel may be considered by adults who want laboratory context relating to:
- Ovarian reserve and possible response to fertility treatment
- Irregular or changing menstrual cycles
- Baseline LH and FSH patterns
- Whether a correctly timed progesterone result is consistent with ovulation
- Acne, increased facial or body hair, scalp hair thinning or other androgen related symptoms
- Planning a discussion about egg freezing, IVF or reproductive health
- Monitoring requested by a GP or fertility professional
People trying to conceive should remember that fertility can be affected by both partners. A full assessment may include medical history, examination, semen analysis, pelvic ultrasound, assessment of the fallopian tubes and other blood tests.
Cycle timing matters
| Biomarker or purpose | Suggested timing |
|---|---|
| AMH | Usually suitable on any cycle day because it is less cycle dependent than LH, FSH and progesterone. |
| Baseline LH and FSH | Early follicular collection, usually cycle days 2 to 5, is preferred for baseline comparison. |
| Progesterone for ovulation | Collect approximately 7 days before the expected next period rather than automatically using day 21. |
| Irregular cycles | Record the date of the last period and cycle day if known. Repeat timed testing may be recommended. |
| After menopause | Use the postmenopausal reference intervals shown on the laboratory report. |
How the home fertility test kit works
Record cycle information
Note day 1 of the last period, the cycle day at collection and any hormone medicines.
Collect and return the sample
Follow the supplied instructions to collect capillary blood and return the microtainer for analysis.
Review the results
Read the report with age, cycle timing and reference intervals and seek professional advice where appropriate.
Preparing for your test
| Preparation | What to do |
|---|---|
| Cycle information | Record the first day of full menstrual bleeding as day 1 and note the exact cycle day at collection. |
| Hormonal contraception | Tell the provider about the pill, injection, implant, hormonal coil or other contraception. Do not stop it without medical advice. |
| Hormone and fertility treatment | Record HRT, fertility medicines, progesterone, testosterone or other hormonal treatment. |
| Biotin | Biotin, vitamin B7, can interfere with some laboratory hormone tests. Ask your doctor whether it should be paused. |
| Hormone gels | Tell the provider if you use or regularly touch testosterone or other hormone gels because contamination can affect results. |
| Pregnancy and recent pregnancy | Pregnancy and the months after pregnancy can substantially change reproductive hormone results. |
| Recent illness | Recent illness, significant stress, weight change and intense exercise may affect some hormone results. |
Understanding the result tables
Reference intervals vary by laboratory method, units, age, cycle stage, pregnancy status and hormone treatment. The interval printed on your individual report takes priority.
Biomarkers and result interpretation
Select each biomarker to read what it measures, preparation guidance and how low, normal, high or undefined results may be considered.
Anti Müllerian hormone
Anti Müllerian hormone, known as AMH, is produced by small follicles in the ovaries. It is used as a marker of ovarian reserve, meaning the remaining pool of follicles that could potentially develop into eggs.
AMH is particularly useful when estimating likely response to ovarian stimulation during fertility treatment. It does not measure egg quality and should not be used to predict whether natural conception will occur.
AMH is less dependent on cycle stage than LH, FSH and progesterone and can often be measured on any cycle day. Hormonal contraception can affect results in some people. Do not stop contraception without speaking with a clinician.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Very low | A very low result may indicate a lower ovarian reserve for age and may be associated with a lower response to ovarian stimulation. | Discuss the result with a GP or fertility specialist. It does not mean that natural conception is impossible. |
| Low | A low result may indicate a lower ovarian reserve for age. Age, hormonal contraception, recent pregnancy, ovarian surgery and some medical conditions may affect interpretation. | Discuss the result with a clinician before making fertility decisions. |
| Normal | The result falls within the laboratory range expected for the relevant age group. | A normal result does not guarantee natural conception, future fertility or egg quality. |
| High | A high result may indicate a larger number of small follicles. It may also occur in people with polycystic ovaries or polycystic ovary syndrome. | Discuss the result with a clinician, especially if cycles are irregular or symptoms suggest androgen excess. |
Luteinising hormone
Luteinising hormone, known as LH, is produced by the pituitary gland. In women it helps regulate the menstrual cycle and triggers ovulation.
LH changes substantially through the cycle and reaches a natural surge around ovulation. It should always be interpreted with the recorded cycle day, FSH, symptoms and medicines.
Record day 1 as the first day of full menstrual bleeding. Early follicular collection, usually days 2 to 5, is preferred when comparing baseline LH and FSH.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | A low result may be normal at some cycle stages. It can also occur with reduced pituitary stimulation, low energy availability, significant weight change, chronic illness or some medicines. | Discuss the result with a doctor in the context of cycle day and symptoms. |
| Normal | The result falls within the reference interval for the recorded cycle stage or postmenopausal status. | A normal result does not confirm normal fertility by itself. |
| High | A high result may represent the normal midcycle LH surge. Outside that context it may occur after menopause, with reduced ovarian function or in some people with polycystic ovary syndrome. | Discuss the result with a clinician before drawing conclusions. |
Free androgen index
Free androgen index, known as FAI, is a calculated value that uses total testosterone and sex hormone binding globulin. It can provide context where symptoms suggest androgen excess, such as acne, increased facial or body hair, scalp hair thinning or irregular cycles.
FAI is not a fertility test by itself and does not diagnose polycystic ovary syndrome or an ovarian or adrenal condition.
Free androgen index is calculated from total testosterone and SHBG. It is an estimate of androgen availability rather than a direct measurement of free testosterone.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | A low result may reflect lower testosterone, higher SHBG, hormone treatment, pregnancy, thyroid or liver factors, or normal variation. | Discuss persistent symptoms with your GP. |
| Normal | The calculated value falls within the laboratory reference interval. | A normal result does not exclude every cause of fertility or cycle concerns. |
| Undefined | The calculation could not be produced or cannot be interpreted reliably, often because testosterone or SHBG was outside the analytical range. | Follow the laboratory recommendation and discuss repeat testing with a clinician. |
| High | A high result may reflect higher testosterone, lower SHBG or both. It can occur with polycystic ovary syndrome, some medicines, hormone use or less common ovarian or adrenal conditions. | See your GP for clinical assessment before making treatment decisions. |
Progesterone
Progesterone rises after ovulation and helps prepare the womb lining for pregnancy. A correctly timed progesterone result can provide evidence consistent with recent ovulation.
Progesterone varies substantially throughout the cycle. A low result taken at the wrong time does not prove that ovulation did not occur.
Girls under 12: below 3.2 nmol/L. Follicular: below 0.616 nmol/L. Ovulatory: 0.175 to 13.2 nmol/L. Luteal: 13.1 to 46.3 nmol/L. After menopause: below 0.401 nmol/L. The laboratory report and cycle timing take priority.
For ovulation assessment, progesterone is commonly measured around 7 days before the expected next period, not automatically on day 21. Tell the provider about hormonal contraception, HRT, implants and fertility medicines.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | A low result may be expected before ovulation, after menopause or when the sample was collected too early or too late. It may also occur in an anovulatory cycle or with some medicines. | Interpret the result against the expected next period and discuss repeat timed testing if needed. |
| Normal | The result falls within the laboratory interval for the recorded cycle stage. | The meaning depends on whether the aim was general hormone assessment or confirmation of ovulation. |
| High | A high result can occur during the luteal phase, pregnancy or with progesterone containing treatment. Less common medical causes are possible. | Discuss an unexpected result with a clinician. |
Sex hormone binding globulin
Sex hormone binding globulin, known as SHBG, is a protein produced mainly by the liver. It binds testosterone and oestradiol and influences how much hormone is available to tissues.
SHBG is used with total testosterone to calculate FAI. It can be influenced by thyroid function, liver health, weight, insulin resistance, pregnancy and hormone medicines.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | Low SHBG may occur with insulin resistance, higher body weight, an underactive thyroid, androgen exposure or some medicines. It can increase calculated FAI. | Discuss the result with your GP in the context of symptoms and other results. |
| Normal | The result falls within the expected interval and supports interpretation of testosterone and FAI. | A normal result does not exclude every hormone related condition. |
| High | High SHBG may occur with pregnancy, an overactive thyroid, liver conditions or oestrogen containing treatment. It can reduce calculated FAI. | Discuss an unexpected result with your GP. |
Total testosterone
Testosterone is present in women as well as men. In women it is produced by the ovaries and adrenal glands and contributes to sexual function, muscle, bone and other physiological processes.
Total testosterone should be interpreted with SHBG, FAI, symptoms, cycle information and medicines.
Tell the provider about biotin, anticonvulsants, anabolic steroids, hormone treatment and regular contact with testosterone gels or creams. Do not stop prescribed treatment unless advised by a clinician.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | A low result may occur with ovarian or adrenal factors, illness, some medicines, hormone treatment or normal individual variation. | Discuss persistent symptoms with your GP. |
| Normal | The result falls within the laboratory reference interval. | A normal result does not exclude every cause of acne, hair changes, irregular cycles or fertility concerns. |
| High | A high result may occur with polycystic ovary syndrome, anabolic steroid or testosterone exposure, some medicines or less common ovarian or adrenal conditions. | See your GP for clinical assessment and possible further testing. |
Follicle stimulating hormone
Follicle stimulating hormone, known as FSH, is produced by the pituitary gland. In women it supports the growth of ovarian follicles and changes throughout the menstrual cycle and reproductive life.
FSH can provide context on pituitary and ovarian signalling, but it is not a direct measure of fertility and cannot predict whether natural conception will occur.
Record the cycle day. Early follicular collection, usually days 2 to 5, is preferred when the aim is to compare baseline FSH and LH.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | A low result may be normal at some cycle stages. It can also occur with reduced pituitary stimulation, low energy availability, significant weight change, chronic illness or certain medicines. | Discuss the result with a doctor in the context of cycle day and symptoms. |
| Normal | The result falls within the reference interval for the recorded cycle stage or postmenopausal status. | Interpret it with LH, AMH, symptoms and medical history. |
| High | A high result may occur as ovarian function declines, including around menopause. It can also occur after some ovarian treatments or with other ovarian conditions. | Discuss the result with your GP, particularly if cycles are irregular or absent. |

Home female fertility test FAQs
What does a female fertility test include?
This home panel includes AMH, LH, FSH, progesterone, total testosterone, SHBG and calculated FAI. It does not include an ultrasound scan, tubal testing, semen analysis, thyroid tests or every investigation used in a fertility assessment.
Can I do a fertility test at home?
Yes. This kit uses a capillary blood sample collected at home and returned for laboratory analysis. Home testing can provide hormone and ovarian reserve context, but it does not replace a full fertility assessment.
What does an AMH test tell you?
AMH provides information about ovarian reserve and may help estimate response to ovarian stimulation. It does not measure egg quality or reliably predict whether natural conception will occur.
Does low AMH mean infertility?
No. A low AMH result does not mean that natural conception is impossible. It indicates a lower ovarian reserve for age and should be interpreted with age, cycle history, ultrasound findings and the wider fertility picture.
What is a good AMH level for my age?
AMH changes with age and laboratory method, so there is no single good number for everyone. Use the age related interval on your report and discuss the result with a clinician.
Can AMH predict menopause?
No. AMH cannot reliably predict the exact age at which an individual will reach menopause.
What day of my cycle should I take a fertility blood test?
AMH can usually be measured on any cycle day. Baseline FSH and LH are often compared during days 2 to 5. Progesterone should usually be timed around 7 days before the expected next period.
Can hormonal contraception affect an AMH test?
Hormonal contraception may influence AMH and other reproductive hormone results in some people. Do not stop contraception without medical advice. Tell the provider what you use and why you are testing.
Does progesterone confirm ovulation?
A correctly timed progesterone result can provide evidence consistent with recent ovulation. A low result does not exclude ovulation if the sample was collected at the wrong time.
Is a home fertility test accurate?
The laboratory can accurately measure the biomarkers in a suitable sample, but clinical meaning depends on cycle timing, medicines, age and the limits of each marker. Accuracy of measurement is not the same as predicting fertility.
When should I see a GP about fertility in the UK?
NHS guidance advises seeking help after one year of regular unprotected sex without conception, or sooner if you are aged 36 or over, have irregular periods, previous cancer treatment or another reason for concern.
Are the laboratories UKAS accredited and CQC registered?
Samples are processed through UKAS accredited laboratories within a CQC registered diagnostic pathway. The home collection equipment is UKCA and CE marked and supported by an ISO 13485 quality management framework.
