【SUMMARY】
Luteinizing hormone (LH, also known as lutropin and sometimes lutrophin[1]) is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH ("LH surge") triggers ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell–stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone.It acts synergistically with follicle-stimulating hormone (FSH).
The increase in LH production only lasts for 24 to 48 hours. This "LH surge" triggers ovulation, thereby not only releasing the egg from the follicle, but also initiating the conversion of the residual follicle into a corpus luteum that, in turn, produces progesterone to prepare the endometrium for a possible implantation. LH is necessary to maintain luteal function for the second two weeks of the menstrual cycle. If pregnancy occurs, LH levels will decrease, and luteal function will instead be maintained by the action of hCG (human chorionic gonadotropin), a hormone very similar to LH but secreted from the new placenta.
The LH Rapid Test Strip (Urine) is a rapid visual immunoassay for the qualitative, presumptive detection of luteinizing hormone in human urine specimens. This kit is intended for use as an aid in the detection of ovulation.

【TEST PROCEDURE FOR Ovulation(LH) RAPID TEST】
Bring tests, specimens to room temperature (15-30°C) before use.
Remove the test from its sealed pouch and use it as soon as possible. For best results, the assay should be performed within one hour.
Hold the strip by the end, where the product name is printed. To avoid contamination, do not touch the strip membrane.
Holding the strip vertically, dip the test strip in the urine specimen for at least 10-15 seconds. Do not immerse past the maximum line (MAX) on the test strip.
As the test begins to work, color will migrate across the membrane.
After the test has finished running, remove the strip from the specimen and place it on a non-absorbent flat surface. Start the timer and wait for the colored band(s) to appear. The result should be read at 5 minutes. Do not interpret the result after 8 minutes.
