The standard kit size of this Luteinizing Hormone Card test kit is 25 tests per box; 40 boxes per carton.

To save freight cost, sometimes bulk packing is used, meaning test strip, cassette or multi-test panel is packed in single aluminum pouch; 50 or 100 pouches in one plastic bag; and then plastic bags are packed in cartons along with the unfolded boxes for the test kits. In this way, the customers can easily pack the tests into test kits after receiving the bulk packed goods.

Materials Provided

  • Test cassette in single foil pouch with desiccant;
  • Disposable sample dropper;
  • Instruction leaflet.

To carry out the assay with a LH Urine Rapid Test Cassette, Urine should be collected according to the instructions given in the Instruction For Use included in the test kit. After collecting, it is preferable to perform the testing as early as possible; if not viable, the specimen should be stored properly. A general introduction about the collection, and storage of the specimens is given below.

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.

Colloidal Gold Chromatographic Immuno Double Antibody Sandwich method is used in this LH Urine Rapid Test Cassette to detect the Luteinizing Hormone (LH) in human Urine specifically. The introduction of this Colloidal Gold Chromatographic Immuno Double Antibody Sandwich testing principle is given blow.

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.
