Each day, a histotechnologist begins by receiving fresh tissue specimens from surgery or biopsy procedures. They then perform a process called grossing, where they prepare the tissue for processing. Next, the tissue is dehydrated and cleared before being embedded in paraffin wax. The embedded tissue block is then precisely sectioned into incredibly thin slices using a microtome. After cutting, these slices are floated onto glass slides. Finally, they apply special stains to the slides, which make specific cellular structures or disease markers visible under a microscope.

Histotechnologists work in hospital pathology laboratories, commercial labs, and research facilities. Their workplaces are technical and require meticulous attention to detail. The lab environment is often quiet and requires focus, as they work with dangerous chemicals and delicate equipment. Their primary collaboration is with pathologists, who rely on them for high-quality slides. They also work with other lab staff, ensuring a smooth workflow. This professional environment is critical for patient safety and accurate diagnosis.

Histotechnologists must hold state licenses in many locations and often earn national certification. The most common certifications are HT (Histotechnician) or HTL (Histotechnologist) from the American Society for Clinical Pathology (ASCP). These credentials demonstrate their competency and adherence to professional standards. Continuing education is required to maintain their certification and to stay updated on new techniques and technologies. Their certifications ensure that they can perform their job accurately and safely.

In 2025, histotechnologists earn between $60,000 and $80,000 a year. Salaries vary based on location and the type of lab they work in, with hospital labs often paying more than commercial labs. Experience plays a significant role in determining income, with senior technologists earning at the high end of the scale. Their income reflects their specialized skills and the critical role they play in the diagnostic process. Histotechnologists who work in management or research may earn even more.

The job outlook for histotechnologists is strong. The aging population and advances in medical technology mean more diagnostic tests and biopsies are being performed. This increased volume of samples creates a steady demand for skilled histotechnologists. Hospitals and labs rely on them to process specimens efficiently and accurately. Their role is a foundational part of the healthcare system, and their future is secure.
