ANTECH Diagnostics® started in 1988. VCA ANTECH, Inc. purchased their first small diagnostic laboratory in West Los Angeles. Shortly after learning the day to day activities with their first laboratory, we partnered with Dr. Lon Rich and Professional Animal Laboratories (PAL) in Southern California. During the years of 1988 to 1995 ANTECH Diagnostics grew to a national company serving the mid west and north east regions.
