Struggling to get pregnant? Wondering what might be causing irregular periods? The answer could lie in your hormone levels—specifically, your luteinizing hormone (LH) levels. LH works closely with follicle-stimulating hormone (FSH) to trigger ovulation. Without these two hormones working in harmony, it becomes significantly harder for a woman to conceive.
At Test Smartly Labs, we offer LH testing services across the Kansas City metro area, helping women take control of their reproductive health with fast, walk-in blood draws and clear lab results.
What Is Luteinizing Hormone (LH)?
Luteinizing hormone (LH) is produced by the pituitary gland and plays a key role in the menstrual cycle and fertility:
-
In women: LH surges mid-cycle to trigger ovulation, releasing an egg from the ovary.
-
In men: LH stimulates the production of testosterone, which is essential for sperm production.
This article focuses on LH testing in women’s health, where low or high levels can cause:
-
Irregular periods
-
Anovulation (no ovulation)
-
Polycystic Ovary Syndrome (PCOS)
-
Infertility
Why You Should Consider LH Testing
If you’ve been trying to get pregnant without success—or are experiencing cycle irregularities—testing your LH levels can reveal crucial hormonal imbalances.
According to the Hormone Health Network:
“About 25% of women with infertility have infrequent or absent ovulation. These women usually have irregular periods or no periods at all.”
This means that understanding your LH levels could help pinpoint why conception isn’t happening—and lead you toward the right treatment or interventions.
When Is LH Testing Recommended?
You may want to schedule an LH blood test if:
-
You’re experiencing difficulty conceiving
-
Your menstrual cycles are irregular or absent
-
You suspect early menopause or PCOS
-
Your doctor is monitoring fertility treatments
-
You are tracking your ovulation window
How Does LH Testing Work?
An LH test is a simple blood draw that measures the amount of luteinizing hormone in your system. Depending on where you are in your menstrual cycle, your doctor might recommend testing on a specific day—usually day 2–5 of your cycle, or mid-cycle to catch the LH surge before ovulation.

What Do LH Test Results Mean?
In Women:

Do You Need A List Of My Medications For A Drug Test?

The MRO will then call your physician to verify your medications.

Understanding STI vs STD
STI stands for “Sexually Transmitted Infection” and STD stands for “Sexually Transmitted Disease”. These two terms sound similar and the difference between them can be confusing. One of the reasons for this is that up to a certain point these two terms were synonymous and were used interchangeably. But now there is a technical difference between these terms which has been acknowledged by the medical community and can no longer be used synonymously.
Privacy Matters for STI/STD Testing at Test Smartly Labs
While all health-related matters deserve the utmost privacy and confidentiality, some types of blood tests and lab work need even more. When it comes to STI or STD testing, you do not want to have any small chance of anyone you know finding out about your risks or diagnoses. Of course, if you go to your doctor’s office or even a public clinic, the HIPAA rules require everyone involved to keep your information private and secure. However, you may still have some doubts troubling your mind.
