Product Description

COVID-19 IgG/IgM Rapid Test Kit

Product Description

REAGEN This kit is used for the qualitative detection of COVID-19 antibodies in human serum,plasma and whole blood samples in vitro. It is only used as a supplementary detection indicator for suspected cases of COVID-19 negative nucleic acid detection or used in conjunction with nucleic acidetection in the diagnosis of suspected cases. It cannot be used as a basis for the diagnosis and exclusion of pneumonitis caused by COVID-19 infection. It is not suitable for screening of the general population. Restricted to medical institutions. A positive test result requires further confirmation. A negative test result does not rule out the possibility of infection.


Mechanism Of Reaction

REAGEN COVID-19 IgG/IgM detection reagent uses the principle of specific binding of antigen and antibodies and immunochromatographic techniques. The reagent contains an anti-human IgM monoclonal antibody fixed in the test area (C) on the test strip in advance. (M) and anti-human IgG monoclonal antibody (G) and goat anti-chicken IgY in the QC region and anti-COVID-19 IgM specific protein-conjugated colloidal gold (M.nC- GC gold label conjugate) and chicken IgY coupled colloidal gold. During the test, the specimen is dropped into the reagent sample well (S). The sample moves to the detection line by capillary chromatography. If there is an IgM antibody against

COVID-19 in the sample, it will be combined with the M.nC-GC gold label conjugate to form an IgM-M.nC-GC complex. This complex continues to migrate forward under the action of chromatography and is captured by an anti-human IgM monoclonal antibody fixed to the M line in advance, forming a wine-red band, indicating that IgM is positive for COVID-19;if IgG antibody of COVID-19, under the action of capillary chromatography, also binds to M.nC-GC and is captured by the G line. It also forms a burgundy band, indicating that the IgG of COVID-19 is positive; if M and G

does not show color, the sample is COVID-19 negative; and COVID-19 IgG/IgM detection reagent contains a built-in quality control line. Regardless of whether IgG/IgM is present in the specimen, a wine-red band will appear in the quality control area ( C). The burgundy band shown in the quality control area (C) is the criterion for judging whether there are enough samples and whether the chromatography process is smooth.

Warnings And Precautions

 This product is a single-use in vitro diagnostic reagent. Do not reuse it. Do not use it if it is





The temperature of the experimental environment should be avoided. The test cards and sample dilutions stored at low temperature should be restored to room temperature before opening to avoid moisture absorption.

Use fresh samples whenever possible, avoid using samples that are contaminated, hemolytic,jaundice or hyperlipidemia.

After the test, treat the used test strips and sample dilutions as biomedical waste.

The desiccant is contained in the packaging bag.

Do not use freeze-thaw samples repeatedly. When testing, please equilibrate the sample to be tested to room temperature.

The test samples should be regarded as infectious agents, and they must be operated in accordance with the infectious disease laboratory operation rules, and pay attention to biological safety operations.

As with all diagnostic reagents, the final diagnosis should be made by the doctor after combining the various indicators and clinical symptoms.

If you have any questions or suggestions during the use of this reagent, please contact the


The kit should not be used in case of damaged packaging.

 Items in each area are for exclusive use, and should not be used crosswise to avoid pollution.Please clean the workbench immediately after the experiment. Please use the tip used in the experiment directly into the waste tank containing 1% sodium hypochlorite, and sterilize with

other waste products before discarding. After removing the reaction tube after amplification, immediately seal it in a special plastic bag and discard it at the designated place. The workbench and various items are regularly disinfected with 1% sodium hypochlorite, 75% alcohol or UV


40 Test Serum / Plasma Sample IgG IgM Detection Reagent 0

Serum/plasma/ whole blood

Serum / plasma sample collection: Serum and plasma should be separated as soon as possible after blood collection to avoid hemolysis. The separated serum and plasma should be tested as soon as possible within 8 hours. If it cannot be used in a timely manner, it should be stored at 2℃ to 8℃for 3 days. If it is more than 3 days, it should be stored at -20℃and stored for less 9 days, pay attention to return to room temperature before testing to avoid repeated freezing and thawing. Severe hemolytic and heat-inactivated samples are not recommended.

Whole blood collection: Use anticoagulation tube to collect blood, or add anticoagulant in the blood


Limitations Of Inspection Methods

1. This product is only suitable for qualitative detection of COVID-19 IgG/IgM in human blood.

2. This product can only be used for IVD.

3. In the early stage of infection, the absence of COVID-19 IgG and IgM antibodies or low titer will lead to negative results, and should be retested within 7-14 days. During the retest, the last sample collected should be tested in parallel to confirm whether there is serological positive or titer

increased significantly.

4. The reference value of serological antibody detection in patients with immunocompromised or immunosuppressive therapy is limited.

5. Positive IgG indicates previous infection or secondary infection.

6. IgM antibody positive occurs not only in the primary infection, but also in the secondary infection.

7. Confirm that the infection with the COVID-19 needs to be combined with the clinical

manifestations of the patient or further combined with other methods.


REAGEN™ COVID-19 IgG/IgM Rapid Test Kit was used to detect 553 human blood samples and compared with the nucleic acid detection method. The results showed that the sensitivity of the test kit was 93.3%, the specificity was 96.6%, and the accuracy was between 80%-95.2%.
