An ovulation home test is used by women to help determine the time in the menstrual cycle when getting pregnant is most likely.The test detects a rise in luteinizing hormone (LH) in the urine. A rise in this hormone signals the ovary to release the egg. This at-home test is often used by women to help predict when an egg release is likely. This is when pregnancy is most likely to occur.

Rapid results: LH rapid tests provide results within minutes, allowing immediate interpretation and action.
Convenience: They are user-friendly and suitable for point-of-care testing in various settings, including clinics, doctor’s offices, and at-home use.
Cost-effectiveness: Compared to laboratory-based tests like ELISA, LH rapid tests are generally more affordable, reducing healthcare costs associated with fertility monitoring and hormone disorder diagnosis.
Colloidal gold immunochromatography
Colloidal gold particles bind to the target substance (LH), producing a specific color change on a test strip, enabling rapid detection of the target substance.
Enzyme-linked immunosorbent assay
An enzyme-labeled antibody reacts with the antigen (LH) to form a complex. Addition of a substrate then produces a color change, which is then measured using an enzyme-linked immunosorbent assay (ELISA) to quantitatively measure LH levels.
Immunochromatography
An in vitro diagnostic test based on immunochromatography, in which specific antibodies bind to the antigen (LH), forming visible lines or spots on the chromatographic membrane.
Applications of LH Rapid Test
Predicting ovulation
LH surge detection helps women time intercourse for conception or assists in fertility treatments like intrauterine insemination (IUI) or in vitro fertilization (IVF).
Monitoring fertility treatments
LH levels are monitored during ovulation induction therapies (e.g., with clomiphene citrate or gonadotropins) to assess treatment response and adjust medication dosages.
Diagnostic tool
LH testing aids in diagnosing hormone disorders such as PCOS (characterized by elevated LH levels) or hypogonadism in men (characterized by low LH levels).
The LH Rapid Test Strip (Urine) is intended for use with human urine specimens only.
Choose a convenient time of the day to collect urine. Reduce liquid intake approximately 2 hours prior to urine collection. Try to collect urine at about the same time each day for the entire cycle.
Do not collect the first urine specimen after waking up.
Turbid specimens should be centrifuged, filtered, or allowed to settle and only the clear supernatant should be used for testing.
Urine specimens must be collected in clean, dry containers. Ensure that the quantity of the specimen collected is sufficient to submerge the dip region of the test strip.
Perform testing immediately after specimen collection. Do not leave specimens at room temperature for prolonged periods. Specimens may be stored at 2-8°C for up to 24 hours. Do not freeze. For best results, test urine on the same day that it is collected.
If specimens are to be shipped, pack them in compliance with all applicable regulations for transportation of etiological agents.
Operation
Remove test Strip, Device or Midstream from the sealed pouch.
Strip
Remove test strip from the sealed pouch. Dip the arrowed end of the test strip into the container containing urine sample, take it out in 5 seconds and lay flat.
Device/Cassette
Remove test device/cassette from the sealed pouch. Lay the device flat, add 2-3 drops of urine specimen by sample dropper into the sample well.
Midstream/Pen
Remove test midstream from the sealed pouch. Open the midstream cup, dip the sample collection head into urine sample, take it out in 5 to 10 seconds and lay flat.

Interpretation of the results
Surge detection: A significant rise in LH indicates impending ovulation, guiding optimal timing for conception or fertility treatments.
Hormone disorders: Elevated or suppressed LH levels can indicate conditions like PCOS or hypogonadism, respectively, prompting further evaluation and treatment.
Sample application: A sample (urine or serum) is applied to the sample pad, where LH in the sample binds to gold-labeled antibodies.
Migration: The sample moves through the nitrocellulose membrane via capillary action.
Detection zone: If LH is present in the sample, it binds to immobilized antibodies in the detection zone, producing a visible line.
Control zone: A control line confirms proper test functioning and sample migration.
The interaction between LH and antibodies on the test strip generates a visible result within minutes, indicating the presence or absence of LH in the sample.
Sample collection timing: Timing of sample collection relative to expected LH surge or hormonal fluctuations can affect test accuracy.
Quality control: Ensuring consistent performance across different batches and manufacturers is essential for reliable test results.
Interpretation guidelines: Proper training and adherence to interpretive guidelines are necessary to avoid misinterpretation of results and ensure clinical validity.
Addressing these considerations helps maximize the reliability and utility of LH rapid test kits in clinical practice.
Storage & Statibility
The kit should be stored at 2-30°C until the expiry date printed on the sealed pouch.
The test must remain in the sealed pouch until use.
Keep away from direct sunlight, moisture and heat.
Do not freeze.
Care should be taken to protect the components of the kit from contamination. Do not use if there is evidence of microbial contamination or precipitation. Biological contamination of dispensing equipment, containers or reagents can lead to false results.
