INTENDED USE

The COVID-19 IgG/IgM Test Cassette is a lateral flow chromatographic immunoassay for the

qualitative detection of IgG and IgM antibodies to COVID-19 in human whole blood, serum or

plasma specimen.

PRINCIPLE

The COVID-19 IgG/IgM Test Cassette (Whole Blood/Serum/ Plasma) is a qualitative membrane-

based immunoassay for the detection of IgG and IgM antibodies to COVID-19 in whole blood,

serum or plasma specimen. This test consists of two components, an IgG component and an IgM

component. In the IgG component, anti-human IgG is coated in IgG test line region. During testing,

the specimen reacts with COVID-19 antigen-coated particles in the test cassette. The mixture

then migrates upward on the membrane chromatographically by capillary action and reacts with

the anti-human IgG in IgG test line region, if the specimen contains IgG antibodies to COVID-19.

A colored line will appear in IgG test line region as a result of this. Similarly, anti-human IgM is

coated in IgM test line region and if specimen contains IgM antibodies to COVID-19, the conjugate-

specimen complex reacts with anti-human IgM. A colored line appears in IgM test line region as a

result.

Therefore, if the specimen contains COVID-19 IgG antibodies, a colored line will appear in IgG test

line region. If the specimen contains COVID-19 IgM antibodies, a colored line will appear in IgM

test line region. If the specimen does not contain COVID-19 antibodies, no colored line will appear

in either of the test line regions, indicating a negative result. To serve as a procedural control, a

colored line will always appear in the control line region, indicating that the proper volume of

specimen has been added and membrane wicking has occurred.

REAGENTS

The test contains anti-human IgM and anti-human IgG as the capture reagent,COVID-19 antigen

as the detection reagent. A mouse anti-goat IgG is employed in the control line system.

PRECAUTIONS

1.For professional in vitro diagnostic use only. Do not use after expiration date.

2.Do not eat, drink or smoke in the area where the specimens or kits arehandled.

3.Do not use test if pouch is damaged.

4.Handle all specimens as if they contain infectious agents. Observe established precautions

against microbiological hazards throughout all procedures and follow the standard procedures for

proper disposal of specimens.

5.Wear protective clothing such as laboratory coats, disposable gloves and eye protection when

specimens are assayed.

6.Please ensure that an appropriate amount of samples are used for testing. Too much or too

little sample size may lead to deviation of results.

7.The used test should be discarded according to local regulations.

8.Humidity and temperature can adversely affect results.

STORAGE AND STABILITY

Store as packaged in the sealed pouch at room temperature or refrigerated (4-30°C) and it is

valid for 24 months. The test is stable to the expiration date printed on the sealed pouch. The test

must remain in the sealed pouch until use. DO NOT FREEZE. Do not use beyond the expiration

date.

SPECIMEN COLLECTION AND PREPARATION

 The COVID-19 IgG/IgM Test Cassette (Whole Blood/Serum/ Plasma) can be performed using

whole blood (from venipuncture or fingerstick), serum or plasma.

 To collect Fingerstick Whole Blood Specimens:

 Wash the patient’s hand with soap and warm water or clean with an alcohol swab. Allow to

dry.

 Massage the hand without touching the puncture site by rubbing down the hand towards the

fingertip of the middle or ring finger.

 Puncture the skin with a sterile lancet. Wipe away the first sign of blood.

 Gently rub the hand from wrist to palm to finger to form a rounded drop of blood over the puncture

site.

 Add the Fingerstick Whole Blood specimen to the test by using a capillary tube:

 Touch the end of the capillary tube to the blood until filled to approximately 10L. Avoid air

bubbles.

 Separate serum or plasma from blood as soon as possible to avoid hemolysis. Use only clear

non-hemolyzed specimens.

 Testing should be performed immediately after the specimens have been collected. Do not leave

the specimens at room temperature for prolonged periods. Serum and plasma specimens may

be stored at 2-8°C for up to 7 days, for long term storage, serum/plasma specimens should be

kept below -20°C. Whole blood collected by venipuncture should be stored at 2-8°C if the test is

to be run within 2 days of collection. Do not freeze whole blood specimens. Whole blood

collected by fingerstick should be tested immediately.

 Bring specimens to room temperature prior to testing. Frozen specimens must be completely

thawed and mixed well prior to testing. Specimens should not be frozen and thawed repeatedly.

 If specimens are to be shipped, they should be packed in compliance with local regulations

covering the transportation of etiological agents.

 EDTA K2, Heparin sodium, Citrate sodium and Potassium Oxalate can be used as the

anticoagulant for collecting the specimen.

MATERIALS

Materials Provided

1)Foil pouches, with test cassettes and disposable droppers

2)Assay buffer

3)Instruction for use

Materials Required But Not Provided

1)Specimen collection container

2)Lancet

3)Centrifuge (for plasma only)

4)Timer

DIRECTIONS FOR USE

Allow the test, specimen, buffer and/or controls to reach room temperature (15-30°C) prior

to testing.

1. Remove the test cassette from the foil pouch and use it within one hour. Best results will be

obtained if the test is performed immediately after opening the foil pouch.

2. Place the cassette on a clean and level surface.

For Serum or Plasma specimen:

 To use a dropper: Hold the dropper vertically, draw the specimen to the fill line

(approximately 10μL), and transfer the specimen to the specimen well (S), then add 2 drops

of buffer (approximately 70μL), and start the timer.

 To use a pipette: To transfer 10 μL of specimen to the specimen well(S), then add 2 drops

of buffer (approximately 70μL), and start the timer

For Venipuncture Whole Blood specimen:

 To use a dropper: Hold the dropper vertically, draw the specimen about 1 cm above the fill

line and transfer 1 full drop (approx. 10μL) of specimen to the sample well(S). Then add 2

drops of buffer (approximately 70 μL) and start the timer.

 To use a pipette: To transfer 10 μLof whole blood to the specimen well(S), then add 2 drops

of buffer (approximately 70μL), and start the timer

For Fingerstick Whole Blood specimen:

 To use a dropper: Hold the dropper vertically, draw the specimen about 1 cm above the fill

line and transfer 1 full drop (approx. 10μL) of specimen to the sample well(S). Then add 2

drops of buffer (approximately 70μL) and start the timer.

 To use a capillary tube: Fill the capillary tube and transfer approximately 10μL of fingerstick

whole blood specimen to the specimen well (S) of test cassette, then add 2 drops of buffer

(approximately 70 μL) and start the timer. See illustration below.

3. Wait for the colored line(s) to appear. Read results at 15 minutes. Do not interpret the result

after 20 minutes.

Note: It is suggested not to use the buffer, beyond 6 months after opening the vial.

INTERPRETATION OF RESULTS

IgG POSITIVE:* Two colored lines appear. One colored line should always appear in the control

line region (C) and another line should be in the IgG line region.

IgM POSITIVE:* Two colored lines appear. One colored line should always appear in the control

line region (C) and another line should be in the IgM line region.

IgG and IgM POSITIVE:* Three colored lines appear. One colored line should always appear in

the control line region (C) and two test lines should be in the IgG line region and IgM lineregion.

*NOTE: The intensity of the color in the test line regions may vary depending on the concentration

of COVID-19 antibodies present in the specimen. Therefore, any shade of color in the test line

region should be considered positive.

NEGATIVE: One colored line appears in the control line region (C). No line appears in the IgG

region and IgM region.

INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural

techniques are the most likely reasons for control line failure. Review the procedure and repeat the

test with a new test. If the problem persists, discontinue using the test kit immediately and contact

your local distributor.

QUALITY CONTROL

Internal procedural controls are included in the test. A colored line appearing in the control region

(C) is an internal procedural control. It confirms sufficient specimen volume and correct procedural

technique. Control standards are not supplied with this kit; however, it is recommended that positive

and negative controls be tested as a good laboratory practice to confirm the test procedure and to

verify proper test performance.

LIMITATIONS

1. The COVID-19 IgG/IgM Test Cassette (Whole Blood/Serum/Plasma) is for in vitro diagnostic

use only. This test should be used for detection of IgG and IgM antibody to COVID-19 in whole

blood, serum or plasma specimens. Neither the quantitative value nor the rate of increase in

the concentration of IgG or IgM antibodies to COVID-19 can be determined by this qualitative

test.

2. The COVID-19 IgG/IgM Test Cassette (Whole blood/Serum/Plasma) will only indicate the

presence of IgG and IgM antibodies to COVID-19 in the specimen and should not be used as

the sole criteria for the diagnosis of COVID-19 infections.

3. As with all diagnostic tests, all results must be considered with other clinical information

available to the physician.

4. If the test result is negative and clinical symptoms persist, additional follow-up testing using

other clinical methods is suggested. A negative result at any time does not preclude the

possibility of COVID-19 infection.

5. The test process and scope of the test must follow the principle of the Instruction manuaI.

6. The results obtained with this test should be interpreted in conjunction with clinical finding, and

the results from other laboratory tests and evaluation.

7. This test should not be used for screening of donated blood.
