What are the Different Types of Dengue Blood Tests & Which is the Most Accurate?
Thousands of people are affected every year by dengue, especially in tropical and subtropical regions. It is transmitted by the Aedes mosquito and presents symptoms like fever, chills, muscle pain, and rash. Early testing plays a crucial role in tailoring treatment for dengue. As the disease progresses quickly and symptoms grow aggressively, it is crucial to have access to a rapid test kit. However, there are many different types of dengue blood test kits, and it is difficult to decide which is the most accurate. In this blog, we will learn about the key features of all test kits.
Types of Dengue Blood Test
Rosewell Remedies provides four types of dengue rapid test kits. Being the best rapid test kit manufacturer in India, our kits are manufactured under the strictest quality control and are engineered to produce the most reliable results. However, there are two main categories of dengue rapid test kits.
➤ Direct Detection Methods: For detecting the virus in the blood.
➤ Indirect Detection Methods: For detecting antibodies against the virus in the blood.
What are the Different Types of Dengue Blood Tests
➤ NS1 Antigen Test
Also known as non-structural protein 1, it is one of the most common diagnostic tests for dengue. It is perfect for early detection, usually within the first week of infection. The dengue NS1 antigen rapid test detects the NS1 protein produced by the dengue. This is a highly sensitive test to be used during the acute stage of infection.
➤ RT-PCR Test
The RT-PCR test is a very reliable and accurate test to detect the presence of dengue. It not only confirms the presence of DNA material of the virus but also finds the type of specific dengue serotype (DEN-1 TO DEN-4). It is very effective to be tested during the first five days of infection.
➤ IgM Antibodies Test
The dengue IgM antibody test detects the presence of IgM antibodies produced by the body in response to viral infection. The dengue IgM rapid test is effective after 7-8 days of infection because the IgM antibodies take time to be produced.
➤ IgG Antibody Test
The IgG antibody test identifies the long-term antibodies produced in response to the dengue virus. It detects the reinfection or the prior infection. The dengue IgG rapid test kit appears around 14 days after the initial infection and persists much longer.
➤ Complete Blood Count
Although not specific to dengue, CBC is essentially for identifying warning signs associated with severe dengue. It monitors platelet counts and hematocrit levels. It helps the medical professional assess the disease progression and bleeding risk.

| RT-PCR Test | Dengue viral RNA | Day 1–5 of infection | Confirms dengue & identifies strain | Very high |
| IgM Antibody Test | IgM antibodies | After Day 4–5 | Detects recent dengue infection | Moderate–high |
| IgG Antibody Test | IgG antibodies | After Day 7–10 | Detects past or secondary infection | Moderate |
| Complete Blood Count (CBC) | Platelets, WBC, hematocrit | Throughout illness | Monitors severity & complications | Supportive only |
| Dengue Combo Test Kit (NS1 + IgM + IgG) | NS1 antigen and IgM/IgG antibodies | Day 1 onward | Detects dengue at different stages in one test | High |
