Dengue IgG/IgM Rapid Test

 

Cat. No.: RF0153D

Dengue IgG/IgM Rapid Test

SAMPLE: Whole Blood / Serum / Plasma

FOR PROFESSIONAL IN VITRO DIAGNOSTIC USE ONLY

 

Intended Use

The One Step Dengue IgA/IgG/IgM Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgA, IgG and IgM) to dengue virus in Whole Blood /Serum / Plasma to aid in the diagnosis of Dengue viral infection.

 

Summary

Dengue is transmitted by the bite of an Aedes mosquito infected with any one of the four dengue viruses. It occurs in tropical and sub-tropical areas of the world. Symptoms appear 3—14 days after the infective bite. Dengue fever is a febrile illness that affects infants, young children and adults. Dengue haemorrhagic fever (fever, abdominal pain, vomiting, bleeding) is a potentially lethal complication, affecting mainly children. Early clinical diagnosis and careful clinical management by experienced physicians and nurses increase survival of patients. One step Dengue IgA/IgG/IgM Test is a simple, visual qualitative test that detects dengue virus antibodies in human Whole Blood/serum/plasma. The test is based on immunochromatography and can give a result within 15 minutes.

 

Principle

The One Step Dengue IgA/IgG/IgM Test is a qualitative membrane strip based immunoassay for the detection of dengue virus antibodies (IgA, IgG and IgM) in Whole Blood /Serum / Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing dengue recombinant envelope antigens conjugated with Colloid gold (dengue conjugates), 2) a nitrocellulose membrane strip containing three test lines (T1, T2and T3 lines) and a control line (C line). The T1 line is pre-coated with the antibody for the detection of IgA anti-dengue, The T2 line is pre-coated with the antibody for the detection of IgM anti-dengue, T3 line is coated with

antibody for the detection of IgG anti-dengue. When an adequate volume of test specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. IgG anti-dengue, if present in the specimen, will bind to the dengue conjugates. The immunocomplex is then captured by the reagent pre-coated on the T3 band, forming a burgundy colored T3 line, indicating a dengue IgG positive test result. IgM anti-dengue if present in the specimen will bind to the dengue conjugates. The immunocomplex is then captured by the reagent coated on the T2 line, forming a burgundy colored T2 line, indicating a dengue IgM positive test result. IgA anti-dengue if present in the specimen will bind to the dengue conjugates. The immunocomplex is then captured by the reagent coated on the T1 line, forming a burgundy colored T1 line, indicating a dengue IgA positive test result. Absence of any T lines (T1, T2and T3 lines) suggests a negative result. To serve as a procedural control, a colored line will always appear at the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred.

 

Storage and Stability

Store as packaged in the sealed pouch at room temperature or refrigerated (4-30℃ or 40-86℉). The test device is stable through the expiration date printed on the sealed pouch.

The test must remain in the sealed pouch until use.

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 and kits are handled. 

3.Handle all specimens as if they contain infectious agents. 

4.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.Follow standard biosafety guidelines for handling and disposal of potential infective material. 

7.Humidity and temperature can adversely affect results.

 

Specimen Collection and Preparation

 

1.The One Step Dengue IgA/IgG/IgM Test can be performed used on Whole Blood /Serum / Plasma.

2. To collect whole blood, serum or plasma specimens following regular clinical laboratory procedures.

3. Testing should be performed immediately after specimen collection. Do not leave the specimens at room temperature for prolonged periods. For long term storage, specimens should be kept below -20℃. Whole blood should be stored at 2-8℃ if the test is to be run

within 2 days of collection. Do not freeze whole blood specimens.

4. 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.

 

Test Procedure

 

Allow the test, specimen, buffer and/or controls to reach room temperature 15-30℃ (59-86℉) prior to testing.

1. Bring the pouch to room temperature before opening it. Remove the test device from the

sealed pouch and use it as soon as possible.

2. Place the test device on a clean and level surface.

3. Hold the dropper vertically and transfer 1 drop of specimen (approximately 10μl) to the specimen well(S) of the test device, then add 2 drops of buffer (approximately 70μl) and start the timer. See illustration below.

4. Wait for the colored line(s) to appear. Read results at 15 minutes. Do not interpret the result after 20 minutes.

 

 

 

Notes:

Applying sufficient amount of specimen is essential for a valid test result. If migration (the wetting of membrane) is not observed in the test window after one minute, add one more drop of buffer to the specimen well.

 

Interpretation of Results

 

 

Positive: Control line and at least one test line appear on the membrane. The appearance of T3 test line indicates the presence of dengue specific IgG antibodies. The appearance of T2 test line indicates the presence of dengue specific IgM antibodies. The appearance of T1 test line indicates the presence of dengue specific IgA antibodies. And if T1, T2 and T3 lines all appear, it

indicates that the presence of dengue specific IgA, IgM and IgG antibodies. The lower the antibody concentration is, the weaker the result line is.

Negative: One colored line appears in the control region(C).No apparent colored line appear in the test line 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 device. If the problem persists, discontinue using the test kit immediately and contact your local distributor.

 

Limitations

 

1.The One Step Dengue IgA/IgG/IgM Test is for in vitro diagnostic use only. The test should be used for the detection of dengue antibodies in Whole Blood /Serum / Plasma specimens only. Neither the quantitative value nor the rate of increase in dengue antibodies can be determined by this qualitative test.

2. As with all diagnostic tests, all results must be interpreted together with other clinical information available to the physician.

3. If the test result is negative and clinical symptoms persist, additional testing using other clinical methods is recommended. A negative result does not at any time preclude the possibility of Dengue viral infection
