What is ns1ag negative?
Negative: The absence of dengue NS1 antigen is consistent with the lack of acute-phase infection. The NS1 antigen may be negative if specimen is collected immediately following dengue virus infection (<24-48 hours) and is rarely detectable following 9 to 10 days of symptoms.
What is dengue hemorrhagic fever?
Mild dengue fever causes a high fever and flu-like symptoms. The severe form of dengue fever, also called dengue hemorrhagic fever, can cause serious bleeding, a sudden drop in blood pressure (shock) and death.
How is dengue hemorrhagic treated?
Treatment for Dengue Fever There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor.
What is difference between dengue fever and hemorrhagic fever?
Despite the name, the critical feature that distinguishes DHF from dengue fever is not hemorrhaging, but rather plasma leakage resulting from increased vascular permeability. EVALUATE the patient’s heart rate, capillary refill, skin color and temperature, peripheral pulse volume, pulse pressure, and blood pressure.
What if dengue NS1 antigen is negative?
A positive NS1 test result confirms dengue virus infection without providing serotype information. A negative NS1 test result does not rule out infection. People with negative NS1 results should be tested for the presence of dengue IgM antibodies to determine possible recent dengue exposure.
How long does dengue IgG stay positive?
In secondary dengue infections, IgG titers rise to extremely high levels (much higher than in primary infections) from the day 7 of fever to the next two weeks (9, 11). Anti-Dengue IgG antibodies persist for a long time even up to years (3, 12).
