€65,00 Free Shipping

Luteinizing hormone (LH) plays an important role in regulating the menstrual cycle. Low LH can cause problems with fertility, while significantly elevated LH levels are common during and after menopause. Use this home hormone test to gain insight into your fertility or understand whether you might be in menopause.

Test Mode: Finger-prick

When to test: It is important to collect the blood sample on Day 3 of your menstrual cycle to ensure accurate results. The third day of your menstrual cycle refers to the third day of blood flow during your period. This means you consume no food or drinks other than water. This test should not be used by women on hormonal birth control.

What is a Luteinizing Hormone Test?

This blood test measures the level of luteinizing hormone (LH) in your blood. LH plays a vital role in controlling the menstrual cycle and ovulation by triggering the release of an egg from the ovary. Abnormal LH levels can indicate issues with ovulation, hormonal imbalances, or underlying health conditions.

The test requires a finger prick blood sample that you can easily take from home. Your sample will then be examined by a certified laboratory and you will receive the results within a matter of days. It couldn’t be easier!

What is Luteinizing Hormone?

Luteinizing Hormone (LH) is a hormone produced in the pituitary gland of men and women. In women, LH is responsible for stimulating the ovaries to release an egg around the middle of the menstrual cycle, also known as ovulation. If fertilization occurs, LH also stimulates the production of other hormones to sustain the pregnancy.

Both too high and low levels of LH can stop ovulation, causing irregular periods or a lack of period altogether. High LH is also linked to polycystic ovary syndrome (PCOS), and may be tested along with other hormones in the process of making a PCOS diagnosis.

Symptoms

Symptoms of high LH

Symptoms of high LH in women usually mimic menopause, and can include:

Irregular menstrual cycle
Hot flashes
Mood changes, including anxiety, irritability, or depression
Fatigue
Sleep disturbances
Vaginal dryness

Symptoms of low LH

Irregular menstrual cycle
Low libido
Hot flashes
Difficulty producing milk (if breastfeeding)

Causes

Causes of high LH

Higher levels of LH can be a a sign of a condition that prevents the ovaries from making normal levels of sex hormones.

Conditions linked to high LH levels in women include:

- Polycystic ovary syndrome (PCOS)
- Primary ovarian insufficiency (POI)
- Menopause or perimenopause
- Damage to the ovaries from an autoimmune condition, chemotherapy, or radiation therapy
- Adrenal gland disorders
- Turner Syndrome

Causes of low LH

Low LH levels can signify that the pituitary gland in the brain isn’t making the LH needed to support sexual development or reproduction. It can also be related to:

Kallmann syndrome
Excessive exercise

About the test results

What do the results of this test mean?

This test measures the level of follicle stimulating hormone in your blood. The results of this test can indicate hormone imbalances that may impact fertility, cause unpleasant symptoms, or indicate a medical condition that affects the production of hormones.

It is important to note that hormone values alone are not enough to predict the chance of pregnancy. Other factors, such as the quality of the egg cells, fallopian tubes, or the partner’s sperm, are also important. If you have questions about your test results or overall fertility, it is best to consult a doctor for comprehensive advice.

For whom is this test applicable?

You have ovaries
You are not using hormonal birth-control at this moment (or within the past three months)
You want to get a better understanding of your hormone levels, risk of hormone-related health conditions, or your fertility

Frequently asked questions

I am on hormonal birth control (pill/ IUD/ Patch), can I still do this test?

This test is not suitable for women using hormonal birth control. As hormonal contraception suppresses ovulation, test results will not be accurate for women using birth control. If you are on hormonal birth control and interested in checking fertility hormones, try Homed-IQ’s Ovarian Reserve Test. This test measures Anti-Mullerian hormone, a hormone that can give an indication of ovarian reserve and can be used by women on birth control. If you stop using hormonal contraception, it is recommended to wait until your third period after stopping birth control to perform a hormone test.

How long do I have to wait after I have stopped taking hormonal birth control to test my hormones?

It is possible to perform this test from the third period after you've stopped taking birth control. In order to get the most accurate results, it is important to wait until your hormones have rebalanced and your period has returned.

How can I test my fertility at home?

This home hormone test involves collecting a small blood sample via a finger prick before sending it off to our ISO 15189 certified lab for testing.

Can I just ask my doctor for this test?

It depends. In some situations there are specific requirements for hormone testing, such as needing to have tried (unsuccessfully) to get pregnant for a year.

Homed-IQ tests are processed by the same labs used by hospitals and clinics, and all are validated for home use.
