What is a DENGUE-PCR?

The **Dengue PCR (Polymerase Chain Reaction) test** is a molecular diagnostic test used to detect the genetic material of the dengue virus in a patient’s blood. Unlike antibody-based tests, PCR identifies the virus directly, making it highly accurate during the early stages of infection. Doctors recommend this test to confirm dengue fever quickly, differentiate it from other febrile illnesses, and guide timely treatment decisions, especially in severe or complicated cases where early diagnosis is critical.
