Veterinary Technicians, often referred to as Vet Techs, licensed veterinary technicians, or LTVs, assist veterinary doctors in the physical care of animals. Their responsibilities include drawing blood, placing catheters, giving medications, and managing anesthesia during surgery. Often, a Vet Tech will be required to prepare animals for surgery or assist with diagnostic tests, including radiographs, urinalysis, and fecal exams. Occasionally, a Vet Tech may even be asked to perform a dental examination. Veterinary Technicians cannot diagnose illness, prescribe medications, or perform surgeries.
