Overview

Think of Luteinizing Hormone (LH) as your body's reproductive conductor, orchestrating the most critical moments in your hormonal symphony. Just like a starter pistol at a race, LH fires at precisely the right moment to trigger essential reproductive events - in women, it creates the dramatic surge that releases a mature egg during ovulation (this is exactly what those ovulation predictor kits are detecting), while in men, it signals the testes to produce testosterone, supporting everything from energy and muscle strength to mood and sexual health.

Testing your LH levels gives you a clear window into how well your reproductive system is functioning and whether your hormones are properly balanced. When LH levels are too high or too low, it can signal issues like PCOS, ovarian problems, testosterone deficiencies, or pituitary imbalances - making this test an invaluable tool for understanding fertility challenges, hormonal symptoms, or reproductive health concerns that might be affecting your daily life.

Symptoms

Essential for women with irregular cycles, fertility issues, or PCOS symptoms. Important for men with testosterone deficiency, fertility problems, or suspected hormonal imbalances. Valuable for investigating ovulation disorders, monitoring fertility treatments, and assessing pituitary function in both genders.

Questions

The LH surge is a rapid increase in LH levels (usually 2-3 times baseline) that triggers ovulation. It typically occurs around day 14 of a 28-day cycle, about 24-36 hours before ovulation.
Yes, LH monitoring is crucial for timing fertility treatments including intrauterine insemination (IUI) and in vitro fertilization (IVF). It helps determine the optimal timing for procedures.
In PCOS, persistently high LH levels contribute to increased androgen production and irregular ovulation. The typical LH:FSH ratio in PCOS is often greater than 2:1.
LH levels help distinguish between primary testicular failure (high LH due to poor testicular response) and secondary hypogonadism (low LH due to pituitary/hypothalamic problems).
Yes, significant physical or emotional stress can temporarily suppress LH production, potentially affecting ovulation timing and test results. It's best to test when relatively stress-free.
Home LH tests are generally reliable for detecting the LH surge in women with regular cycles, with accuracy rates of 85-95%. However, laboratory testing provides more precise measurements.

How to prepare

Timing is critical for women. For ovulation detection, daily testing around mid-cycle may be needed. For general assessment, day 3 of cycle is preferred. For LH surge detection, testing should occur when ovulation is expected. No fasting required. Avoid testing during illness or extreme stress as these can temporarily affect results.

After the test

Consult with a reproductive health specialist to interpret results in context. Abnormal LH levels may require additional testing including FSH, testosterone, oestradiol, or pituitary imaging. Treatment options depend on the underlying cause and may include ovulation induction, hormone therapy, or fertility treatments. Serial testing may be needed for ovulation tracking.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Normal ranges vary by gender and cycle phase. Women (follicular): 2-10 IU/L; Women (ovulation surge): 20-80 IU/L; Women (luteal): 1-12 IU/L; Post-menopausal: 10-60 IU/L; Men: 1-10 IU/L. High baseline levels may indicate PCOS, ovarian failure, or testicular dysfunction. Low levels might suggest pituitary or hypothalamic problems.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

Frequently Asked Questions

Do I need to book ahead?

Most collection centres accept walk-ins. Some may require a booking - check details when you click on your chosen location.

How do I know if I need to fast?

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

What do I need to bring?

Just your pathology referral form (we email it to you)

Can I bring someone with me?

Of course. Just maybe don’t bring the friend who faints at the sight of blood.

What’s a phlebotomist?

They’re the highly trained professionals who take your blood sample - with a steady hand and a sharp needle. They love blood, but don’t worry… they’re not vampires. Just legends who make blood tests quick, clean, and (almost) painless.

What other samples may I need to provide for my test?

Some of our tests include Urine, Stool, Saliva and more. Each test will have a clear description on what sample you will need to give and instructions on how.
