AMCA MHTC case studies
AMCA MHTC · Put your knowledge to work in context.
The AMCA Medical Histology Technician Certification (MHTC) is a credential offered by the American Medical Certification Association for laboratory professionals who prepare tissue specimens for microscopic examination. It is aimed at histology technicians and technologists, laboratory assistants moving into histology, and students completing a histology or clinical laboratory training program who want a recognized entry-level credential. The AMCA MHTC case studies are 5 cases and about 2,362 words.
1The Shrunken Breast Core Series
A pathology assistant submits 14 breast core biopsies from a single patient in one cassette, each core 1.2 cm long and 1.5 mm in diameter, fixed in 10% NBF for 4 hours before transport. The next morning the tissue processor runs an abbreviated overnight cycle (70% ethanol through three xylene steps, 3 hours total).
