Dengue Chikungunya Antibody combo test kit 2 in1

The Dengue & Chikungunya Antibody Combo Test Kit (2-in-1) is a qualitative in vitro diagnostic immunoassay designed for the rapid detection of IgM and IgG antibodies against Dengue virus (DENV) and Chikungunya virus (CHIKV) in human whole blood, serum, or plasma samples.

This combo test enables simultaneous screening for two common mosquito-borne infections that often present with similar clinical symptoms, such as acute fever, joint pain, headache, and fatigue. It serves as a valuable aid for the timely clinical assessment of acute or recent infections, especially in patients with epidemiological risk factors or recent travel to endemic regions.

Using immunochromatographic technology, the test delivers fast and easy-to-interpret results, helping healthcare professionals make early diagnostic decisions and improve patient management in clinical and point-of-care settings.

Key Features:

• 2-in-1 combo test for Dengue and Chikungunya
• Detects IgM and IgG antibodies
• Suitable for whole blood, serum, or plasma
• Rapid results for early clinical decision-making
• Ideal for use in endemic and travel-related infection screening

How to know if it’s dengue or chikungunya?

Dengue fever and Chikungunya often have similar early symptoms, such as fever and body aches, making them difficult to distinguish clinically. However, they can be differentiated by rash characteristics, joint symptoms, and blood test findings, and confirmed with laboratory testing.

1. Rash Characteristics

• Chikungunya:
  The rash is usually a diffuse red or maculopapular rash, often accompanied by intense itching. The palms and soles may also be involved. In some cases, hemorrhagic rashes (petechiae or ecchymosis) can occur.

• Dengue:
  The rash is typically measles-like or scarlet fever-like, usually without itching. In severe cases, skin bruising or nosebleeds may appear due to bleeding tendency.

2. Joint Symptoms

• Chikungunya:
  Severe joint pain is a hallmark feature. It commonly affects small joints of the hands and feet, is often symmetrical and migratory, and can be very intense. Some patients may develop chronic arthritis that persists for months.

• Dengue:
  Joint pain is generally milder, mainly involving large joints such as the knees and ankles. Long-term joint complications are rare after recovery.

3. Blood Test Findings

• Both diseases:
  Thrombocytopenia (low platelet count) is common.

• Dengue:
  Platelet reduction is often more severe (sometimes <20 × 10⁹/L) and is usually accompanied by marked leukopenia (low white blood cell count), increasing the risk of bleeding.

• Chikungunya:
  Platelet counts may decrease but are usually less severe than in dengue.

✅ Key Takeaway

• Chikungunya: prominent, severe joint pain + itchy rash

• Dengue: higher risk of bleeding + marked drop in platelets and white blood cells

Because symptoms can overlap, laboratory confirmation—such as IgM/IgG antibody tests, antigen tests, or PCR—is essential for an accurate diagnosis and appropriate management.
