LH One Step Ovulation Test Strip

LH, or luteinizing hormone, is a reproductive hormone linked with ovulation. Before ovulation, LH rises sharply in urine. This rise is called the LH surge. The LH One Step Ovulation Test Strip is designed to detect this surge and help users understand when ovulation is likely. Ovulation tests are often used to help determine the time in the menstrual cycle when pregnancy is most likely, and users may need to test for several days to detect the LH surge.

The LH One Step Ovulation Test Strip (Urine) is intended for the qualitative detection of LH in urine. It is used as an ovulation prediction aid and fertility screening support tool.

Applications

• Ovulation prediction
• Fertility tracking
• Women’s reproductive health screening
• Gynecology clinic testing
• Fertility center support
• Diagnostic laboratory use
• International fertility product distribution

The LH One Step Ovulation Test Strip by LARKSOIS Pharma uses the colloidal gold method. In this rapid immunochromatographic method, LH in the urine sample reacts with specific antibodies on the strip. If LH is present at or above the test’s detection level, a visible test line appears along with the control line.

Benefits

• Fast visual result format
• Simple strip-based testing
• No complex instrument required
• Suitable for urine sample testing
• Compact and easy to distribute
• Useful for fertility and women’s health programs
• Practical for international diagnostic markets

The correct specimen for the LH One Step Ovulation Test Strip is urine. Ovulation tests may be used by placing the strip into urine collected in a clean container, depending on the product format.

Guidance

• Collect urine in a clean and dry container
• Dip the strip only up to the marked line
• Avoid excessive fluid intake before testing
• Test around the same time each day during the fertile window
• Read results within the instructed time window
• Follow the LARKSOIS Pharma product insert carefully

Note

Do not drink large amounts of fluids before using an ovulation test because diluted urine may affect LH detection.

Steps

• Bring the test strip and urine sample to room temperature
• Open the sealed pouch only when ready to test
• Collect urine in a clean, dry container
• Dip the strip into urine up to the marked line
• Keep the strip dipped for the recommended time
• Remove and place it on a clean, flat surface
• Read the result within the approved time window

Note

The exact procedure should follow the official LARKSOIS Pharma product insert. A typical LH One Step Ovulation Test Strip workflow may include dipping the strip in urine for 15–20 seconds, placing it on a flat surface, and reading results within the stated time.

Positive

A positive result usually appears when the test line is equal to or darker than the control line, depending on the product insert. This suggests an LH surge and indicates that ovulation may occur soon.

Negative

A negative result usually means the LH surge has not been detected. Testing may continue daily during the expected fertile window.

Invalid

If the control line does not appear, the result is invalid. Use a new LH One Step Ovulation Test Strip and repeat the test with a fresh urine sample.

Testing days depend on menstrual cycle length. For a 28-day cycle, testing may begin around day 11, and in general testing should begin 3 to 5 days before the expected ovulation date.

Note

For users with irregular cycles, repeated testing or professional guidance may be needed. The LH One Step Ovulation Test Strip can help track the LH surge, but it should not be used as the only method for diagnosing fertility concerns.
