Cancer can often be detected by the appearance of cells in a tissue sample. Once a sample tissue is taken from the patient, it's sent to the laboratory. It's the job of the histotechnician (HT) to prepare very this sections of body tissues, mount them on slides and stain them with special dyes to make cell details visible by microscopic evaluation by a pathologist.
A Histotechnologist (HTL) has advanced training in collection and processing of tissue samples. This advanced training qualifies the histotechnologist to provide technical problem solving and evaluation of new laboratory techniques or procedures.
