Device Gmate Rtk COVID-19 Ag Rapid Test Kit Sodium Azide

COVID-19 Ag Rapid Test Device Gmate Rtk

Intended Use

The kit is for qualitative testing of nCoV Ag 2019 strains taken from human nose wipe samples.
The 2019 nCOV is the new nCOV. Viral pneumonia can be caused and the main clinical symptoms are fever, lethargy and dry cough. Many patients have symptoms such as stuffy nose, runny nose, sore throat, and diarrhea. Severe patients usually develop dyspnea and / or hypoxemia after 1 week, and severe patients rapidly develop acute respiratory distress syndrome, infectious shock, difficulty in correcting metabolic acidosis, coagulation dysfunction, etc. Proceed.
This product was qualitatively tested by transverse flow immunoassay on a pseudo-nasal wipe sample of 2019 nCoV Ag. During the acute phase of infection, antigen is usually detected in nasal swap samples. A positive result indicates the presence of a viral antigen, but a clinical correlation between the patient's medical history and other diagnostic information is also needed to identify the infection status. Positive results do not rule out bacterial or mixed infections with other viruses.
This kit can be used by the general public at home in non-laboratory environments (human homes and non-traditional places such as offices, sporting events, airports, schools). The test results of this kit are for clinical reference only. It is advisable to perform a full analysis of the condition based on the patient's clinical symptoms and other laboratory tests.

Principle of Detection

This kit is an immunoassay kit based on the principle of two-antibody concentric technology. The 2019 ncov monoclonal antibody bearing this marker was sprayed onto the binding sheet as an indicator marker. During the course of the test, the 2019 ncov Ag in the sample is bound to the labeled 2019 ncov monoclonal antibody to form the ag-ab complex. The complex was elevated by the capillary effect and was separately packaged on the test line until the sandwich complex was formed by the 2019 ncov monoclonal antibody. A red stripe appeared in the T zone of ncov Ag in 2019. This is the explanation window in the sample. Otherwise, this is a negative result. The control line (c) is used for program control. If the test program runs correctly, it should always be visible.

Main Components

The kit consists of a test card, sample buffer and a wipe.
Test card: Consists of aluminum foil packaging, desiccant, test sheet, plastic card. Of these, the test paper consists of a water-absorbent paper, a cellulose nitrate film, a test sample pad, an adhesive pad and a rubber plate. The nitrocellulose membrane T line (test line) is packaged with 2019 nCOV Ab, C line (QC line), coated with goat anti-mouse multiclonal antibody, and the binding pad is labeled 2019 nCOV Ab.
Sample buffer: Phosphate, sodium nitride, etc.

Storage Conditions and Validity

Stay at 2 ℃ ~ 30 ℃, tentatively valid for 18 months.

The unpacking aluminum foil package is valid for one hour.

Production batch number: See the label for details.

Validity period: See the label for details.

Sample Requirements

(1)How to remove the nostril: Insert the sample swap into the nostril and insert the tip into the nostril edge 2.5 cm. Turn the brush 5 times along the mucous membrane of the nose and repeat the same for the other nose with the same brush.(see Figure 1)

Figure 1 Collection method for nasal swab

(2) Sample processing: Collected samples should be treated with the sample buffer provided by the kit as soon as possible (if not immediately, stored in a dry, sterile, sealed container), stored within 2 hours, temperature 24 hours ° C. Maintain -70 ° C without exceeding ~ 8 ° C (but avoid repeated freezing and thawing)

Test Method

Please read the instructions carefully before the test. Bring all reagents to room temperature before testing. The test should be conducted at room temperature.
1 Sample processing (see Fig. 2)
1. Insert the sample swap into the sample buffer and rotate it approximately 10 times near the inner wall to allow the sample to dissolve as much as possible in the solution.
2. Squeeze the tip of the wipe along the inner wall of the tube, pour as much liquid as possible into the tube, take out the wipe and put it in the house.
3. Cover with water drops.

Figure 3 Detection procedure

2. Test procedure (see Figure 3)

1. took out the exam card.

The 2. adds 2 drops (about 80 μ50) extracts the processed sample into the loading hole of the test card and then activates the timer.

3. read the results after 15 minutes at room temperature. Invalid results after 20 minutes.

Interpretation of Test Results

Test card description (Figure 4):
Invalid ① Result: Quality control line (C line) The response line is invalid and should be rediscovered.
② Negative result: Quality control line (C) is a red ribbon.
③ Positive result: 2 red bands, test (T) and quality control (C).

Limitation of test method

1. This product is used for qualitative tests and is used only for in-vitro assisted diagnosis.
2. This product is suitable for nose wipe samples. The results of other types of samples may be inaccurate or invalid.
3. An appropriate amount of sample must be added and tested. If the sample size is too large or too small, the results may be inaccurate.
4. The test results of this reagent are for clinical reference only and cannot be the sole basis for clinical diagnosis and treatment. A final diagnosis can be made after a comprehensive evaluation of all clinical and laboratory results.
