There are three laboratories:

Reference Histology  |  Electron Microscopy (TEM)  |  Immunopathology

Laboratory directors are recognized authorities in their fields, with extensive technical knowledge as well as a thorough understanding of the concerns of their clinical and research clients. Technical staff rank among the best in the country, also, exemplifying Hopkins' high professional standards.

Expect same-day review of heart biopsies. Final written reports will be faxed within three days, unless special studies such as electron microscopy or immunohistochemistry are required. In that case, reports may take several days longer. Dr. Hruban is available for telephone consults 8:00 a.m. to 5:00 p.m.
