Why testing may be needed
Fever can be due to viral, bacterial, parasitic or inflammatory causes. Doctors may use history, examination and blood tests to decide treatment.
Common fever tests
CBC, malaria parasite tests, dengue NS1/IgM, CRP, urine routine, liver function and blood culture may be considered depending on duration and symptoms.
Warning symptoms
Seek urgent care for breathlessness, confusion, very low urine, severe dehydration, persistent vomiting, bleeding, severe abdominal pain or very high fever.
Avoid self-diagnosis
Similar symptoms can occur in different infections. Test results should be reviewed by a qualified doctor.
Frequently asked questions
Follow your doctor’s prescription. CBC is common but not enough for every fever case.
Many blood tests can be collected at home, but urgent symptoms need medical evaluation.
