LH One Step Ovulation Test Device

LH, or luteinizing hormone, is produced by the pituitary gland and plays an important role in reproductive health. In women, LH rises sharply before ovulation. This sudden increase is called the LH surge, and it usually occurs before the release of an egg from the ovary. Because the LH surge happens before ovulation, the LH One Step Ovulation Test Device can support fertility tracking by helping users identify their most fertile days.

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

Applications

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

The LH One Step Ovulation Test Device by LARKSOIS Pharma uses the colloidal gold immunochromatographic method. In this method, specific antibodies react with LH in the urine sample. If LH is present at or above the test cut-off, a visible test line appears along with the control line.

Benefits

• Fast visual result format
• Simple urine-based testing
• No complex instrument required
• Easy-to-read control and test lines
• Suitable for professional and point-of-care use
• Practical for clinics, laboratories, and distributors
• Convenient fertility testing format

The correct specimen for the LH One Step Ovulation Test Device is urine. Urine testing is convenient, non-invasive, and widely used for ovulation prediction.

Guidance

• Use a clean and dry urine container
• Avoid drinking large amounts of fluids before testing
• Test at the same time each day during the fertile window
• Follow the LARKSOIS Pharma product insert carefully
• Read the result only within the approved time window
• Do not reuse the test device

Note

Excessive fluid intake before testing may dilute urine and affect LH detection.

The LH One Step Ovulation Test Device by LARKSOIS Pharma has a stated 30 mIU/mL cut-off. This means the device is designed to detect an LH surge when urine LH reaches or exceeds the validated threshold. LARKSOIS Pharma should mention the exact sensitivity and cut-off only as confirmed by its final product IFU and technical documentation.

Steps

• Bring the test device and urine sample to room temperature
• Open the sealed pouch only when ready to test
• Place the device on a clean, flat surface
• Add the required number of urine drops into the sample well
• Wait for the colored lines to appear
• Read the result within the stated time window
• Do not interpret results after the approved reading time

Note

The official LARKSOIS Pharma instructions for use should always be followed. Testing steps may vary depending on the final product design.

Positive

A positive result usually shows both the control line (C) and test line (T), with the test line meeting the interpretation criteria stated in the product insert. A positive result suggests an LH surge, meaning ovulation may occur soon.

Negative

A negative result usually means LH is not detected at the surge level or is below the cut-off. Testing should continue over the recommended days because LH surge timing varies between users.

Invalid

If the control line does not appear, the test is invalid. The test should be repeated with a new LH One Step Ovulation Test Device and a fresh urine sample.

• LH testing may be especially useful for women trying to conceive, women tracking cycles, and healthcare professionals supporting fertility planning.
• The test should not be used as contraception. Ovulation urine tests are designed for fertility tracking and ovulation prediction support, not pregnancy prevention.
