LH Test For Women reagent is exposed to urine, allowing urine to migrate through the absorbent test strip. The labeled antibody- dye conjugate binds to the LH in the specimen forming an antibody- antigen complex. This complex binds to the anti- LH antibody in the test region ( T) and produces a red line when LH concentration is equal to or greater than 25 mIU/ ml. In the absence of LH, there is no line in the test region (T). The reaction mixture continues flowing through the absorbent strip past the test region ( T) and control region (C). Unbound conjugate binds to the reagents in the control region ( C) , producing a red line, demonstrating that the test strip is functioning correctly.

Test Procedure
Read the entire procedure carefully before performing any tests.
Allow test strip and urine samples to equilibrate to room temperature (2 0 - 30℃or 68-86℉) prior to testing.
1.Remove the test strip from the sealed pouch.
2.Hold the dropper vertically and transfer 3 full drops of urine to the
specimen well of the test strip, and then begin timing.
3.Wait for colored lines to appear. Interpret the test results at 5minutes.
NOTE: Do not read the result after 5 minutes.
Performance Characteristics
Sensitivity:
The Luteinizing hormone Rapid test will detect LH concentrations over 2 5 mIU/ ml .
The addition of Follicle Stimulating Hormone ( FSH, 10 0 0 mIU/ml) and Thyroid
Stimulating Hormone (TSH, 100 0 mIU/ ml) to negative specimens (0 mIU/ ml LH)
showed that these hormones do not impact the ovulatory period test results.
Cross-Reactivity:
The following potentially interfering substances were added to either LH negative
urine specimens or LH positive urine specimens, none of the substances at the
concentration tested interfered in the assay.
FAQ
Q:What is the LH test for females?
FAQ
Q: What is the LH test for females?
A: What is a luteinizing hormone (LH) levels test? This test measures the level of luteinizing hormone (LH). A hormone is a chemical messenger in your bloodstream that controls the actions of certain cells or organs. LH is usually measured in a sample of your blood. But in certain cases, it may be measured in urine (pee).
Q: What is a normal LH for a woman?
A: Women, follicular phase of menstrual cycle: 1.68 to 15 IU/mL. Women, midcycle peak: 21.9 to 56.6 IU/mL. Women, luteal phase: 0.61 to 16.3 IU/mL. Women, postmenopausal: 14.2 to 52.3 IU/mL.
Q: Does low LH mean low fertility?
A: Low LH most often occurs due to malnutrition (which can happen due to an eating disorder, obesity, or another health condition) or a pituitary gland condition. Low LH can also occur due to a hormonal health condition and may result in infertility.
Q: Is high or low LH better?
A: A high or low LH level isn't simply good or bad. For instance, a surge in your LH can show that you're about to ovulate. You're most likely to become pregnant at this time. This information that LH provides about your fertility is helpful if you're trying to have a baby.
Q: How is LH related to PCOS?
A: Reproductive system abnormalities - The cause of PCOS is not completely understood. With regards to the reproductive system, it is believed that abnormal levels of the pituitary hormone luteinizing hormone (LH) and high levels of male hormones (androgens) interfere with normal function of the ovaries
Q: When should I take my LH test?
A: The best time to take an ovulation test is with the second morning urine – roughly between 10 am and noon. The ovulation predictor test looks for a hormone called LH or luteinizing hormone in your urine. LH hormone surges 24 to 36 hours before you ovulate.
Q: Can stress affect LH levels?
A: For example, prolonged stress will initially have the responses mentioned above, but it will consistently inhibit LH release and then eventually block ovulation all together by peripheral mechanisms like altering the responsiveness of the pituitary and gonadal systems.
Q: Why would a doctor order an LH test?
A: Doctors may order an LH test if puberty starts earlier or later than expected. The test also can check for damage or disease of the testes or ovaries, pituitary gland, or hypothalamus, an area of the brain that links the nervous system with the hormone-making endocrine system.
Q: Does LH test need fasting?
A: Fasting: For the LH test, fasting is typically not required. However, follow your healthcare provider’s instructions if other tests (such as FSH, estradiol, or testosterone tests) are being performed at the same time. Avoiding Stress: Stress can influence hormonal levels, including LH.
