LH Ovulation Rapid Test

LH urine strip, LH urine cassette and LH midstream are used to qualitatively predict the LH surge, and in turn when one is likely to ovulate.

LH Ovulation Test Kit

Intended Use

Atlas Link Technology Co. Ltd supplies LH ovulation rapid test kits in three formats: LH urine strip, LH urine cassette and LH midstream. All are based on the chromatographic immunoassay principle, and are used to qualitatively predict the LH surge. The testing results are mainly used to predict the LH surge, and also can be used to as an indicator of certain dysfunctions.

When Take LH Tests

The best times to test are between 11:00 am to 3:00 pm and between 5:00 pm to 10:00 pm. To ensure that you do not miss your surge, you may test twice a day, once in the earlier time frame and once at later time. The detection limit for the LH Test Kit is 30 mIU/ml LH.

When testing with a LH Ovulation rapid test device, the first thing to do is to determine the length of the menstrual cycle. If the cycle is shorter than 21 days or longer than 38 days, a doctor should be consulted on when to start. Or else, when not knowing the cycle length, one can also begin the test 11 days after the first period, since the average menstrual cycle length is 28 days. Perform one check each day over a 5-day period, or until the LH surge is detected.

Why Predict LH Surge

During the reproductive years, typical LH levels are between 1-20 IU/L. LH increases dramatically just before a woman's most fertile day of the month in a process commonly referred to as the "LH Surge", which triggers ovulation. Because the egg can only be fertilized between 6 to 24 hours after ovulation, detecting ovulation in advance by testing for the LH surge is very helpful for women seeking pregnancy.

But because sperms can stay viable in the woman's body for several days, LH tests are NOT suitable as a contraceptive measures, as the LH surge typically occurs after the beginning of the fertile window.

Materials Provided in the Test Kit

  • Lateral Flow immunochromatographic assay (GICA) Strip;
  • Instruction leaflet;

Specimen

Urine Collection

A urine specimen must be collected in a clean and dry container.

For hormone test such as HCG prenancy test, the first urine specimen in the morning is preferred since it generally contains the highest concentration of hormone, although urine specimens collected at any time of the day may be used.

Urine specimens exhibiting visible particles should be centrifuged, filtered, or allowed to settle to obtain clear specimen for testing.

urine Storage Condition

Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For long-term storage, specimens may be frozen and stored below -20°C.

Frozen specimens should be thawed and mixed before testing.

Testing Principle of Lateral Flow Double Antibody Sandwich

GICA Double Antibody Sandwich Method Illustration

In the double antibody sandwich lateral flow chromatographic rapid test, two antibodies are used to detect viral protein or antigen.

In the test band region, antibody specific to the target antigen or protein is immobilized. In the end of the membrane strip where the samples are added, another antibody conjugated with colloidal gold particles is embedded.

During the testing process, specimen from the patient is added to the end of the membrane strip. The antibody conjugate particles will resolve into the specimen, where the antibody conjugate will react and bound to the target protein or viral antigen, if present.

This antigen-antibody conjugate complex then moves along the strip to the testing band region, under capillary effect. The immobilized antibody in the test line region then bound to another binding site on the antigen complex, and the antibody-antigen-antibody complex is fixed on test band region.

When the complex congregates, the highly concentrated colloidal gold particles will develop some red or pink color, indicate a positive result.

If there is no target protein or antigen in the specimen, the colloidal gold particles will not congregate and no color will develop, indicating a negative result.
