Dengue IgG/IgM Rapid Test Cassette


1. Product Details

Product Name: The Dengue IgG/IgM Rapid Test Cassette

Format: Cassette

Test Item: IgG and IgM antibodies to Dengue virus

Specimen: Whole Blood/Serum/Plasma

Storage: 2-30°C

2. Principle

The Dengue IgG/IgM Rapid Test Device (Whole Blood/Serum/Plasma) is a qualitative membrane-based immunoassay for the detection of Dengue antibodies in whole blood, serum, or plasma. This test consists of two components, an IgG component and an IgM component. In the IgG component, anti-human IgG is coated in test line region 1 of the test. During testing, the specimen reacts with Dengue antigen-coated particles in the test strip. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with the anti-human IgG in test line region 1. If the specimen contains IgG antibodies to Dengue, a colored line will appear in test line region 1. In the IgM component, anti-ligand is coated in test line region 2 of the test. During testing, the specimen reacts with ligand anti-human IgM. Dengue IgM antibodies, if present in the specimen, reacts with the ligand anti-human IgM and the Dengue antigen-coated particles in the test strip, and thiscomplexiscapturedby theanti-ligand,forminga coloredlineintestlineregion2. 

Therefore, if the specimen contains Dengue IgG antibodies, a colored line will appear in test line region 1. If the specimen contains Dengue IgM antibodies, a colored line will appear in test line region 2. If the specimen does not contain Dengue 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 change from red to blue in the control line region, indicating that the proper volume of specimen has been added and membrane wicking has occurred.

3. Directions for Use

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

(1) Bring the pouch to room temperature before opening. 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.

For Serum or Plasma Specimens:

Hold the dropper vertically, draw the specimen up to the Fill Line (approximately 5 μL), and transfer the specimen to the specimen well (S) of the test device, then add 3 drops of buffer (approximately 90μL) and start the timer. See illustration below. Avoid trapping air bubbles in the specimen well(S).

For Whole Blood (Venipuncture/Fingerstick) Specimens:

To use a dropper: Hold the dropper vertically, draw the specimen 0.5-1 cm above the Fill Line, and transfer 1 drop of whole blood (approximately 10 µL) to the specimen well (S) of the test device, then add 3 drops of buffer (approximately 90uL) and start the timer. See illustration below. 

Touse a micropipette: Pipetand dispense 10 µL ofwhole blood tothe specimen well(S) of the test device,then add 3 drops of buffer (approximately90µL) and start the timer.See illustration below.

(3) Wait for the colored line(s) to appear. Read results at 10 minutes. Do not interpret the result after 20 minutes.
