Fever (Adult)
Information and suggested lab tests.
What it is
Fever is a rise in body temperature, most often due to infections. Tests help identify common causes and guide care when fever is high, persistent, or you have warning signs.
Diagnosis and tests
Based on symptoms and local outbreaks, testing may include CBC, CRP/ESR, dengue/malaria screening, urine test, or cultures. Early testing is helpful if fever is high or prolonged.
Treatment and management
Rest, fluids, and fever control as advised by a clinician. Avoid self-starting antibiotics; treatment depends on the cause. Seek urgent care for red flags.
FAQs
Do I need tests for every fever?
Not always. Testing is most helpful if fever is high, lasts more than 2–3 days, or you have concerning symptoms.
Can I eat before fever tests?
Most fever-related tests do not need fasting. If fasting is required for a specific test, the lab will inform you.
When should I go to hospital?
If you have breathing difficulty, confusion, severe weakness, dehydration, or any red flags, seek urgent care.
