Lake Worth's approximately 5,000 residents are served by a community known for the Lake Worth reservoir and Castle Hills. What Lake Worth doesn't have is a freestanding emergency room equipped to evaluate and treat high or persistent fevers around the clock — with on-site labs, blood cultures, and IV antibiotics when a bacterial infection is found. The nearest hospital ER can mean a long wait with a sick child or feverish family member; Lake Worth-area urgent care clinics typically close by evening and cannot run cultures or start an IV.
That's why so many Lake Worth families rely on ER Of Fort Worth at 4561 Heritage Trace Parkway — just 16 miles from Lake Worth via Hwy 199 & I-820. We are open 24 hours a day, 7 days a week, 365 days a year. When a fever spikes in the middle of the night near the Lake Worth reservoir and Castle Hills, our team is ready. A full fever workup — including rapid flu/strep/COVID testing, a complete blood count, and imaging if needed — begins within minutes of your arrival.

Should I go to urgent care or an ER for a high fever in Lake Worth?
It depends on severity. Mild fevers in healthy adults can often be managed at an urgent care near Lake Worth. But any fever above 103°F, a fever in an infant under 3 months, fever with a stiff neck or confusion, or a fever that has lasted more than three days needs ER-level care — including on-site labs, blood cultures, and IV antibiotics if a bacterial infection is found. Most Lake Worth-area urgent cares cannot run cultures or start an IV on the spot.
How quickly will my fever be evaluated after arriving from Lake Worth?
Fever is triaged quickly, especially in infants, older adults, or anyone showing signs of dehydration or confusion. Our average wait time across all conditions is under 10 minutes, and high-risk fever presentations from Lake Worth are brought back immediately.
Will my insurance cover an ER visit from Lake Worth TX for a fever?
Yes. We accept BCBS, Aetna, Cigna, UnitedHealthcare, Humana, Medicare, Tricare and most major commercial plans. Emergency evaluation of a high or persistent fever is covered as emergency care under EMTALA regardless of network status. See our full insurance details at /insurance/.
Do you treat fevers in children from Lake Worth?
Yes. Our ER physicians are trained in pediatric emergency care and routinely treat infants, children and adolescents from Lake Worth with fever — including newborns, whose fevers always require immediate evaluation. See our Pediatric ER page for more.
How long until I get fever test results?
Most blood work and rapid flu, strep, and COVID swab results come back within 30-60 minutes. Blood and urine cultures take 24-48 hours to fully process, but we begin treatment immediately based on your symptoms and initial labs — Lake Worth patients are never left waiting on a culture before care begins.
Can Lake Worth residents use online check-in for a fever visit?
Yes — and we encourage it for non-critical fevers. Our online check-in at /online-check-in/ lets you submit your information before leaving Lake Worth so our staff can begin intake preparation. For a fever above 103°F, an infant under 3 months, or any fever with confusion, stiff neck or rash, call or come straight in rather than pausing to fill out a form.
