The Importance of Lab Testing

While laboratory testing and services are not always necessary, they are often incredibly invaluable in providing fast, accurate diagnoses of various conditions. Lab testing is a critical aspect of modern health care and a key component of analyzing and evaluating a patient’s overall health.

At ER of Texas, we utilize advanced laboratory testing in order to:

  • Obtain prompt and precise diagnoses
  • Develop effective treatment plans
  • Provide clear, straightforward prognoses
  • Enact timely treatment
  • Maximize patient engagement
  • Confirm health findings
  • Create a comprehensive picture of a patient’s overall health and wellness

Because our modern lab facilities are on-site, we are able to provide faster results without having to wait for findings to come back from off-site labs. This allows our physicians to quickly analyze results and create personalized treatment plans for each individual patient.
