CTMC Laboratory Enhances Capabilities, Upgrades Equipment

SAN MARCOS, TX Renovations were recently completed to the Central Texas Medical Center (CTMC) Laboratory and starting next month, two new Roche analyzers will expand the available test menu and improve overall efficiency of the certain lab studies.


The new analyzers allow 9-minute testing using only one tube of blood, where the previous equipment required two different types of blood specimens and took 14 minutes to produce results. The Troponin T and Pro-BNP tests are used to diagnose and assess the risks of cardiac conditions, specifically acute coronary syndrome and congestive heart failure. The upgrade also allows testing on expectant mother labs to be completed in-house rather than sending specimens to a separate, resource laboratory.


“The new tests are more sensitive and specific than the ones they are replacing,” CTMC Laboratory Director David Erb said. “These state-of-the-art instruments allow faster turn-around times and help us produce more precise results for our patients.”


Tests added to the CTMC Lab Services menu include:

  • Anti-CCP
  • Rheumatoid Factor
  • Lithium levels
  • Hepatitis Bs Antigen
  • Hepatitis Bs Ab
  • Hepatitis A Virus
  • Beta-Hydro butyrate Acetone test
