Diagnostic Kit for Luteinizing Hormone fluorescence immunochromatographic assay)
For in vitro diagnostic use only
Please read this package insert carefully prior to use and strictly follow the instructions. Reliability of assay results cannot be guaranteed if there are any deviations from the instructions in this package insert.

INTENDED USE
Diagnostic Kit for Luteinizing Hormone (fluorescence immunochromatographic assay) is a fluorescence immunochromatographic assay for the quantitative detection of Luteinizing Hormone (LH) in human serum or plasma, which is mainly used in the evaluation of pituitary endocrine function.All positive sample must be confirmed by other methodologies. This test is intended for healthcare professional use only.

SUMMARY

Luteinizing hormone (LH) is a glycoprotein with a molecular weight of about 30,000 Dalton, which is produced by the anterior pituitary. The concentration of LH is closely related to ovulation of ovaries, and the peak of LH is predicted to be 24 to 36 hours of ovulation. Therefore, the peak value of LH can be monitored during the menstrual cycle to determine the optimal conception time. Abnormal endocrine function in the pituitary gland can cause LH secretion irregularity.The concentration of LH can be used to evaluate pituitary endocrine function. The Diagnostic Kit is based on immunochromatography and can give a result within 15 minutes.

PRINCIPLE OF THE PROCEDURE

The membrane of the test device is coated with anti LH antibody on the test region and goat anti rabbit IgG antibody on the control region. Lable pad are coated by fluorescence labeled anti LH antibody and rabbit IgG in advance. When testing positive sample, the LH antigen in sample combine with fluorescence labeled anti LH antibody, and form immune mixture. Under the action of the immunochromatography, the complex flow in the direction of absorbent paper, when complex passed the test region, it combined with anti LH coating antibody, forms new complex. LH level is positively correlated with fluorescence signal, and the concentration of LH in sample can be detected by fluorescence immunoassay assay.

REAGENTS AND MATERIALS SUPPLIED

25T package components：

.Test card individually foil pouched with a desiccant 25T
.Sample diluents
.Package insert

MATERIALS REQUIRED BUT NOT PROVIDED
Sample collection container,timer

SAMPLE COLLECTION AND STORAGE
1.The samples tested can be serum, heparin anticoagulant plasma or EDTA anticoagulant plasma.
2.According to standard techniques collect sample. Serum or plasma sample can be kept refrigerated at 2-8℃ for 7days and cryopreservation below -15°C for 6 months.
3.All sample avoid freeze-thaw cycles.

ASSAY PROCEDURE

The test procedure of the instrument see the immunoanalyzer manual. The reagent test procedure is as follows
1.Lay aside all reagents and samples to room temperature.
2.Open the Portable Immune Analyzer(WIZ-A101), enter the account password login according to the operation method of the instrument, and enter the detection interface.
3.Scan the dentification code to confirm the test item.
4.Take out the test card from the foil bag.
5.Insert the test card into the card slot, scan the QR code, and determine the test item.
6.Add 20μL serum or plasma sample to sample diluent, and mix well..
7.Add 80μL sample solution to sample well of the card.
8.Click the “standard test” button, after 15 minutes, the instrument will automatically detect the test card, it can read the results from the display screen of the instrument, and record/print the test results.
9.Refer to the instruction of Portable Immune Analyzer(WIZ-A101).

TEST RESULTS AND INTERPRETATION

.The above data is the reference interval established for the detection data of this kit, and it is suggested that each laboratory should establish a reference interval for the relevant clinical significance of the population in this region.
.The concentration of LH is higher than the reference range, and the physiological changes or stress response should be excluded.Indeed abnormal, should combine clinical symptom diagnosis.
.The results of this method are only applicable to the reference range established by this method, and the results are not directly comparable with other methods.
.Other factors can also cause errors in detection results, including technical reasons, operational errors and other sample factors.

STORAGE AND STABILITY
1.The kit is 18 months shelf-life from the date of manufacture. Store the unused kits at 2-30°C. DO NOT FREEZE. Do not use beyond the expiration date.
2.Do not open the sealed pouch until you are ready to perform a test, and the single-use test is suggested to be used under the required environment (temperature 2-35℃, humidity 40-90%) within 60 mins as quickly as possible.
3.Sample diluent is used immediately after being opened.

WARNINGS AND PRECAUTIONS
.The kit should be sealed and protected against moisture.
.All positive specimens shall be validated by other methodologies.
.All specimens shall be treated as potential pollutant.
.DO NOT use expired reagent.
. NOT interchange reagents among kits with different lot No..
.DO NOT reuse test cards and any disposable accessories.
.Misoperation, excessive or little sample can lead to result deviations.

LIMITATION
.As with any assay employing mouse antibodies, the possibility exists for interference by human anti-mouse antibodies (HAMA) in the specimen. Specimens from patients who have received preparations of monoclonal antibodies for diagnosis or therapy may contain HAMA. Such specimens may cause false positive or false negative results.
.This test result is only for clinical reference, should not serve as the only basis for clinical diagnosis and treatment, the patients clinical management should be comprehensive consideration combined with its symptoms, medical history, other laboratory examination, treatment response, epidemiology and other information.
.This reagent is only used for serum and plasma tests. It may not obtain accurate result when used for other samples such as saliva and urine and etc.
