Welcome to the Texas Health Rockwall Laboratory Services Test Catalog (THRW LTC)

We have created THRW LTC to provide pertinent information and resources to caregivers to facilitate optimal patient outcomes. Lab test collection criteria, ordering, processing, result interpretation, adminstrative, and ordering recommendation (right margin of specific test) are available through THRW LTC. In addition to testing information pertinent tip sheets, URL links, and resources are accessible to you.
