Dengue Virus by PCR
Dengue Virus by PCR is used to diagnose dengue fever caused by dengue virus, especially after a journey to tropical areas.
Results and Meanings:
- Positive: There is dengue infection.
- Negative: There may be no dengue infection. Antibody testing is needed.
Antibody Testing Results and Meanings:
Antibody (IgG, IgM) Testing results can be presented in two ways:
Positive or Negative:
- Positive: It’s likely that the dengue infection happened within recent weeks. But it’s also possible that it is a different infection caused by other viruses, such as chikungunya.
- If the IgG test result is positive while the IgM is negative, it may indicate that there used to be a dengue infection.
Antibody Titer:
| IgM Result | IgG Result | Possible Interpretation |
| Positive | Negative | Current Infection |
| Positive | Positive | Current Infection |
| Negative/Low/Not Tested | Four-fold increase | Recent Infection |
| Negative | Positive | Past Infection |
| Negative | Negative | Equivocal |
