Tests Doctors May Order
| Test | Purpose |
|---|---|
| FBC | Check for bacterial infection (raised WBC) vs viral |
| CRP | Bacterial infection marker |
| Urine dipstick/culture | UTI is a common hidden cause of fever in young children |
| Blood culture | If sepsis suspected |
| Chest X-ray | If breathing symptoms present |
Meningitis Warning SignsNon-blanching rash, stiff neck, unusual drowsiness, high-pitched crying, bulging soft spot (infants). Press a glass against the rash — if it doesn't fade, call 999 immediately.
Fever ManagementParacetamol or ibuprofen can help comfort, but fever itself is not dangerous unless very high (>40°C) or the child seems very unwell. Dress lightly, offer fluids, and don't over-bundle.
Should I always give medicine for fever?
Only if your child is uncomfortable. Fever helps fight infection. Treat the child's comfort, not the number on the thermometer.
Can teething cause high fever?
Teething can cause a very mild temperature rise but not a true fever (>38°C). Any real fever needs another explanation.
How long can a viral fever last?
Most viral fevers resolve within 3–5 days. If fever persists beyond 5 days, seek medical review.
