Dengue IgG Test

The Dengue IgG Test is a blood test that checks for antibodies produced by your body in response to a dengue infection.

The average Dengue IgG test price across India is around Rs 950, though the cost may vary depending on the location and diagnostic lab.

Being Dengue IgG antibody positive means that you have previously been infected with the dengue virus.

The Dengue IgG Test is typically recommended when you display symptoms of dengue fever or if you've travelled to a high-risk area.

The main differences between Dengue IgG lie in their timing of appearance post-infection, longevity, and what they indicate. IgG antibodies appear around day 14 after infection onset; these persist for life providing long-term immunity.

A high level of Dengue IgG indicates that you had a Dengue infection in the past.

No. Fasting is not typically required before this test.

Dengue IgG test results are usually available within 6-10 hours. However, this may vary based on the specific lab and its processing times.

The Dengue IgG test measures the level of Dengue IgG antibodies in your blood. These antibodies are your body's response to previous dengue virus exposure, indicating immunity against future infections.

At Metropolis Healthcare, you can expect to receive your Dengue serology test reports within 6 hours of sample collection. Speed matters when it comes to diagnosing dengue and commencing appropriate treatment!

The Dengue IgG test is also known as Dengue Antibody Test or Dengue Serology.

Dengue igg test is done for diagnosis of dengue infection. It should ideally be done after 2 weeks of development of symptoms in patient. Most patients will develop IgG antibodies against dengue by 2-3 weeks post primary infection. However, when the patient has dengue for the second time (secondary dengue) the IgG antibodies rise within 2 days of development of symptoms.
Patients, post first infection with a different serotype of dengue virus can develop severe form of disease with the following symptoms: abdominal pain, persistent vomiting, bleeding from nose, gums, blood in stool and restlessness.

A Dengue IgG Test gets done to:

• Diagnose dengue virus infection
• Diagnose a current or recent exposure to the dengue virus
• Indicate that the patient became infected with the dengue virus in recent times
• Determine if the patient has ever had dengue fever.

The dengue IgG test should be done by:

1. People who have recently visited an area where dengue infection is common should go for a dengue IgG test.
2. People having these warning signs should do the dengue IgG test:

• Stomach pain
• Vomiting more than three times a day
• Tenderness of stomach
• Restlessness
• Lethargy
• Mucosal bleed
• Enlarged liver.

It takes 3–14 days to show symptoms of dengue in the human body.

Symptoms of the mosquito-borne dengue virus infection are as follows:

• Fever
• Nausea and Vomiting
• Rash
• Pain behind the eyes
• Muscle aches
• Bone pain
• Diarrhea
• Joint pain
• Inflammation of stomach.

Dengue igg detects presence of dengue virus in the blood

The test measures the presence of dengue virus IgG antibodies in the bloodstream.

The blood sample is taken from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a  little sting when the needle goes in or out. This usually takes less than five minutes.

A healthcare provider will take your blood sample. An elastic band will get tightly tied to the upper arm. Your skin will be disinfected with cotton soaked in alcohol. The healthcare provider inserts the needle into your vein just above your elbow to collect your blood. The blood will then be poured into a serum separator tube. You may sense a prick when the needle enters and exits your vein. The healthcare provider then puts clean cotton over the punctured area. 

Negative

Dengue IgG antibodies increase after 5–7 days of acute infection. The following considerations can help detect the presence of dengue virus IgG antibodies:

• Positive: More than 2.85 IV
• Negative: Less than 1.64 IV
• Equivocal: 1.65–2.84 IV (Questionable presence of antibodies).

A positive IgG result is consistent with exposure to dengue virus. Time of collection of sample is important for interpretation of results. Patients with secondary dengue (at risk of severe dengue) develop IgG antibodies early on in the disease. It is important to remember that IgG antibodies remain positive for years together and should not be interpreted in isolation.
A negative IgG test can result if sample is collected early on in the primary infection. A timely collected sample with negative result means lack of exposure to dengue virus in immunocompetent person

No preparation is required for the dengue IgG Test.

Dengue IgG Antibodies are usually detectable after the 9th day of dengue virus infection. IgG antibodies last for months to years.

Dengue NS1 gets secreted into the blood during dengue virus infection. It gets detected within 3–4 days of dengue infection. It helps in the early diagnosis of dengue. IgG antibodies are usually detectable after the 9th day of dengue virus infection.

There are Three Stages of Dengue:

• Febrile (Fever) – The first 3 days of the infection where the patient has a fever of 39–40 degrees C along with weakness, eye pain, joint pain, and body aches.
• Critical – Lasts from the 3rd to 7th day of infection when fever and blood pressure get reduced. The patient experiences restlessness, weakness, cold skin, rapid heart rate, vomiting of blood, and internal bleeding.
• Convalescent (Recovery) – The recovery period starts from the 8th day and lasts about 3–5 days. The patient returns to a normal state and feels hungry, and their pulse becomes normal. The only symptom during this stage is a rash on the arms and legs.
