Lab-Scientist Precision
26 years of MLS-certified laboratory experience behind every collection. Most collectors aren't scientists — Stephen is.

About Stephen Christian
After 26 years in the United States Air Force as a Medical Laboratory Scientist (MLS), Stephen Christian brought military-grade precision to the civilian testing industry in San Antonio. While most mobile collectors are trained only in collection procedures, Stephen is a fully credentialed lab technician — meaning every specimen he handles is touched by someone who understands the science behind the result.
He founded Precision because he saw a gap in San Antonio's testing landscape — businesses needed compliant, dependable DOT drug testing without sending employees to clinics for hours; families needed honest, confidential DNA collection handled with respect.
