What is the prognosis of dengue fever?

The prognosis for dengue is usually good. The worst symptoms of the illness typically last 1 to 2 weeks, and most patients will fully recover within several additional weeks. Typical dengue infection is fatal in less than 1% of cases; however, the more severe dengue hemorrhagic fever is fatal in 2.5% of cases.

What indicates dengue in blood test?

Immunoglobulin M (IgM) This test looks for IgM (antibodies) in the blood, which appear in the early course of the disease (acute infection). The test can also help to differentiate between primary (first time infection) and secondary (second time infection with any of the dengue virus) infection.

How can I check dengue report?

If an infection is suspected, you will get a blood test to check for the dengue virus. During a blood test, a health care professional will take a blood sample 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.

What is IgG positive in dengue test?

IgG as a sero-marker of Dengue infection. If the IgG is positive but the IgM is low or negative, then it is likely that the patient had an infection sometime in the past. Presence of IgG alone (absence of NS1 Ag and/or IgM), does not indicate active dengue infection.

Can dengue be detected by CBC blood test?

The clinical presentation of dengue patients is acute febrile illness with no localizing signs and symptoms which may mimic other infections. Therefore the laboratory tests such as a complete blood count (CBC), serological test or blood culture need to be used to differential and confirm the diagnosis.

What is the WBC count in dengue?

Dengue fever is characterized by leucopenia (White Blood Cells (WBC) < 5000 cells/mm3), thrombocytopenia (< 150,000 cells/mm3), rising haematocrit (5–10%) and there should be no evidence of plasma leakage [10].

What is the normal range of dengue?

Reference Range: Dengue Fever Virus Antibody, IgG 1.64 IV or less: Negative - No significant level of detectable dengue fever virus IgG antibody. 1.65-2.84 IV: Equivocal - Questionable presence of antibodies. Repeat testing in 10-14 days may be helpful.

What is IgG IgM and NS1?

Dengue Antigen NS1, IgG and IgM test detects the non-structural protein component (NS1) of the dengue virus and the antibodies (IgG & IgM) produced by the body in response to the infection. NS1 and IgM is secreted into the blood during dengue infection and are detectable within 3-4 days of illness.

Is CRP high in dengue?

CRP levels in patients with dengue were higher than patients with potential viral infection but lower than patients with potential bacterial infection, resulting in a quadratic association between dengue diagnosis and CRP, with levels of approximately 30 mg/L associated with the highest risk of having dengue.

What is dengue IgG and IgM?

Positive IgM and IgG tests for dengue antibodies detected in an initial blood sample mean that it is likely that the person became infected with dengue virus within recent weeks. IgM antibody tests can be positive if a person has been infected with a similar virus, such as chikungunya (called cross-reaction).

Does WBC decrease in dengue?

Dengue fever can result in a drop in your white blood cell and platelet counts. The normal platelet count in the body ranges from 1.5 to 4 lacs, this can go down to as low as 20,000 to 40,000 in the case of dengue patients.

What is normal WBC?

The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens.

Why is WBC low in dengue fever?

This study may suggest that leukopenia in dengue fever may be caused by virus-induced destruction or inhibition of myeloid progenitor cells. Thrombocytopenia may result from by destruction of peripheral platelet or bone marrow megakaryocytes by viruses which consequently reduce the platelet production.
