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 24/7 freestanding emergency room with a full in-house laboratory. The nearest hospital ER can mean hours of waiting for lab results; Lake Worth-area urgent cares typically close by evening and send tests out to third-party labs, with results taking a day or more.
That's why so many Lake Worth residents 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 you need answers fast near the Lake Worth reservoir and Castle Hills, our team runs same-visit lab work — CBC, metabolic panels, cardiac biomarkers, infection markers, and drug screens — with most results back in under an hour.
