Comprehensive Dengue Combo Test Kit - QL Biotech

Short Description:

The Leishmania IgG/IgM Rapid Test is a lateral flow immunoassay for the qualitative detection of antibodies including IgG and IgM to the subspecies of the Leishmania donovani (L. donovani), the Visceral leishmaniasis causative protozoans in human serum or plasma. This test is intended to be used as a screening test and as an aid in the diagnosis of the disease of Visceral leishmaniasis. Any reactive specimen with the Leishmania IgG/IgM Rapid Test must be confirmed with alternative testing method(s).

In the ever-evolving landscape of biotechnology and medical diagnostics, QL Biotech stands at the forefront with its revolutionary Leishmania IgG/IgM Rapid Test Device. Now, taking a stride further, we are proud to introduce our cutting-edge Dengue Combo Test Kit, an epitome of precision and reliability. This qualitative membrane strip-based immunoassay is meticulously designed for the detection of dengue virus antibodies (IgG and IgM) in Whole Blood/Serum/Plasma, offering a crucial tool in the swift diagnosis and management of Dengue Fever.

PRINCIPLE

HSV‐1 IgG/IgM (HSV-2 IgG/IgM)Test is a qualitative membrane strip based immunoassay for the detection of HSV‐1 antibodies (IgG and IgM) in Whole Blood/Serum/Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing HSV recombinant envelope antigens conjugated with Colloid gold (HSV conjugates) and rabbit IgG‐gold conjugates,2) a nitrocellulose membrane strip containing two test bands (T1 and T2 bands) and a control band (C band). The T1 band is pre‐coated with the antibody for the detection of IgM anti‐HSV, T2 band is coated with antibody for the detection of IgG anti‐HSV, and the C band is pre‐coated with goat anti rabbit IgG.

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‐HSV, if present in the specimen, will bind to the HSV conjugates. The immunocomplex is then captured by the reagent pre‐coated on the T2 band, forming a burgundy colored T2 band, indicating a HSV IgG positive test result and suggesting a recent or repeat infection. IgM anti‐HSV if present in the specimen will bind to the HSV conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a HSV IgM positive test result and suggesting a fresh infection. Absence of any T bands (T1 and T2) suggests a negative result. The test contains an internal control (C band) which should exhibit a burgundy colored band of the immunocomplex of goat anti rabbit IgG/rabbit IgG‐gold conjugate regardless of the color development on any of the T bands. Otherwise, the test result is invalid and the specimen must be retested with another device.

PROCEDURE

    • 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. For Whole Blood, Serum or Plasma specimens: Hold the dropper vertically and transfer 2 drops of specimen (or approximately 50 µL) to the specimen well (S) of the test device, then add 1 drop of buffer for serum or plasma and 2 drops of buffer for whole blood. Start the timer. 
      For Fingerstick Whole Blood specimens: 
      To use a capillary tube: Fill the capillary tube and transfer approximately 50 µL (or 2 drops) of fingerstick whole blood specimen to the specimen well (S) of the test device, then add 2 
      drops of buffer and start the timer. 
      3. Wait for the colored line(s) to appear. Read results at 15 minutes. Do not interpret results after 30 minutes. 

    INTERPRETATION OF RESULTS



    IgMPositive:* The colored line in the control line region (C) appears and a colored line appears in test line region 2 (T2). The result is positive for Leishmania specific‐IgM antibodies.

    IgGPositive:* The colored line in the control line region (C) appears and a colored line appears in test line region 1 (T1). The result is positive for Leishmania specific‐IgG.

    IgG and IgM Positive:* The colored line in the control line region (C) appears and two colored lines should appear in test line regions 1 and 2 (T1 and T2). The color intensities of the lines do not have to match. The result is positive for IgG & IgM antibodies.

    *NOTE: The intensity of the color in the test line region(s) (T1 and/or T2) will vary depending on the concentration of Leishmania antibodies in the specimen. Therefore, any shade of color in the test line region(s) (T1 and/or T2) should be considered positive.

    The colored line in the control line region (C) appears. No line appears in test line regions 1 or 2 (T1 or T2).

    Controlline(C) falls toappear.Insufficient buffer volume or incorrect procedural techniques are the most likely reasons for control line failure.

    Review the procedure and repeat the procedure with a new test device. If the problem persists, discontinue using the test kit immediately and contact your local distributor.




    The Dengue Combo Test Kit embodies the pinnacle of diagnostic innovation, merging the sensitivity required for early detection with the specificity needed to differentiate between the four serotypes of the dengue virus. Its user-friendly interface ensures that healthcare professionals can conduct tests with ease and confidence, ensuring rapid results without compromising accuracy. The strategic incorporation of both IgG and IgM antibodies enhances the test's effectiveness, facilitating not only the identification of an ongoing infection but also providing insight into past exposures to the virus. Delving deeper into the operational excellence of the Dengue Combo Test Kit, it operates on a solid-phase immunochromatographic assay principle. The process initiates when a specimen is applied to the sample well of the test device. As the sample migrates through the absorbent material, it encounters conjugated dengue antigens. If dengue-specific IgG or IgM antibodies are present in the specimen, they will bind to these conjugates, forming antigen-antibody complexes. This complex moves further along the strip to the test line region, where pre-coated dengue antigens capture the complex, producing a visible line as a positive indication. The simplicity, combined with the efficiency of this process, underscores the test kit's value in rapidly responding to dengue outbreaks, crucial for effective disease management and control measures.
