What is dengue test all about?
Dengue fever is a type of viral infection transmitted into humans from mosquitoes that live in tropical and subtropical climates and carry the virus with them. Dengue test identifies the dengue virus either antibody produced in the response of dengue infection. As per the Centers for Disease Control and Prevention (CDC), dengue infections report in a maximum of 100 countries from parts of Africa, the Caribbean, the Eastern, and the Americas.
What dengue IgG positive mean?
IgM plus IgG tests are used to find dengue antibodies. Positive IgM states that the person having the check has suffered from an infection recently. In case IgG is positive. Also, IgM is negligible, following it signifies that a mosquito had infected the individual in the past.
When you need to go for a Dengue test?
You can need this Dengue test if you live or traveled to a place where Dengue is usual, and you have signs of dengue fever. Symptoms commonly show up four to eight days following being bitten from an infected mosquito and can include:
- Quick high fever (104°F either higher)
- Swollen glands
- Strict headache plus pain behind the eyes
- Rash on face
- Joint as well as muscle pain
- Nausea and vomiting
DHF called Dengue hemorrhagic fever causes extra severe symptoms as well as might be life-threatening. In case you’ve had signs of dengue fever either have been in place which has Dengue, you could be in danger for DHF. Go for medical help immediately in case you either your child has one and more of the following signs:
- Harmful abdominal pain
- Blood in urine as well as stools
- Vomiting which doesn’t go away
- Nose bleeds
- Bleeding gums
- Bleeding of skin that may look like bruises.
- Cold, clammy skin
- Difficulty breathing
How does dengue fever cause?
It is a vector-borne disease caused by the bite of a mosquito that is infected. Serotypes of this virus have four types that cause Dengue. These are called DEN-1, DEN-2, DEN-3, DEN-4. Deadly Dengue is a lethal complication that can develop from dengue infections. It calculated that there are about 50-100 million Dengue records worldwide every year and 3 billion people staying in Dengue endemic nations. Dengue is generally transmitted from a mosquito known as Aedes aegypti plus distributed around all tropical nations (map present). Ae. Aegypti and various species like Ae. Albopictus is mainly adaptive, and their mixed distribution might spread Dengue greater up north across Europe either North America in summer. (Remember: Travelers already infected, and the virus also increases the disease while they bit from the Aedes mosquito local population). Dengue outbreaks might occur anytime, as extended as mosquitoes are still active. In general, greater humidity and temperature conditions favor mosquito survival, improving the possibility of transmission. Thus dengue test is very much important for people who those symptoms are like dengue.
What is Ns1?
This NS1 antigen check, where NS1 represents nonstructural protein1, is an advanced test for Dengue introduced in 2001. Rapid diagnosis of fever might be performed on the initial day itself, even devoid of the antibodies’ sight within the infection response. It initially launched in India in 2010.
What does dengue test result outcome?
Molecular testing—PCR test that detects the availability of the virus is usually considered the very reliable type of diagnosis for this virus test. A positive outcome from a PCR is known as conclusive. An adverse effect on a PCR test can indicate that zero infection is available or that the range of the virus is shallow to identify. It may happen if the test done following the 7-day window in that the virus is available in the sample taken for this examination. A negative PCR outcome followed through antibody testing (below).
Positive IgM plus IgG checks for dengue antibodies found in a basic blood sample states that it possible that the person got infected with the dengue virus just in recent weeks. IgM antibody checks might be positive if a person infects with the same virus, like chikungunya (known as cross-reaction). In case an initial IgM antibody check is positive, a second examination known as the Plaque Reduction Neutralization Test (PRNT) utilize to confirm the activity of antibodies for the dengue virus and support rule out various viral infections.
In case the IgG is positive. Still, the IgM is low either negative, after it possible that the person faced an infection sometime in the near past. In case this dengue IgG antibody titer boosts four-fold either greater (for example, the titer of 1:4 till a titer of 1:64) within a first sample plus one was taken two till four weeks later, following a person may have had a recent infection.
Negative tests for IgM either IgG antibodies can mean that the person examined doesn’t have a dengue infection, and symptoms are because of another cause, either that the range of antibody can be very low for measuring. The person can have a dengue infection – it can only be that it is very soon following initial exposure for this virus to get to a detectable range of antibodies.
How to prevent dengue fever?
Presently, there is zero immunization, preventing a person from contracting dengue fever if exposed to the virus. Avoiding exposure till the virus relies upon protecting versus mosquito bites. While traveling in tropical weather, wear insect repellent which contains DEET plus long sleeved-shirts and long pants. Stay indoors in dawn and dusk while mosquitoes are very active.
What are the issues of dengue fever?
A small percentage of Dengue people can develop a severe type of disease called dengue hemorrhagic fever.
Risk causes for having this fever are:
- To have antibodies left about from previous infections.
- Being female
- Being a child within the age of twelve
- Have a slow immune system
The rare disease characterized from:
- High fever
- Harm to blood vessels
- Harm to the lymphatic system
- Circulatory System failure
- Nose bleeds
- Liver enlargement
Signs of the fever might trigger dengue shock syndrome. Its form is much severe and might lead to extra bleeding and else death.
Is this fever contagious?
Dengue fever is non-contagious because it cannot straightway directly from person to person contact. It can just be transmitted from a bite by an infected mosquito. Because the fever is due to a virus, antibiotics can’t assist in its treatment.
What must I do in case I suspect I have Dengue?
In case you have doubts about Dengue, you are required to see a physician immediately. To identify dengue fever, your consultant would:
- Evaluate your signs as well as symptoms;
- Check your blood for proof of a dengue virus;
- Check you’re medical plus travel history.
Those who had traveled to dengue-endemic countries in the past two weeks must inform the doctor regarding it.
Why Delhi labs are best?
Delhi labs are great in their services. They also send reports online if someone has emergency. The place is very hygienic and takes proper care of the patients.
