Predominantly clinical experience that occurs at UNM Hospital and its supporting clinical laboratory, TriCore Reference Laboratories (TRL). Emphasis is placed on cementing diagnostic accuracy in Pap smears and non-gyn specimens such as fine needle aspirate (FNA) specimens, endoscopic-guided biopsies, and specimens obtained by washings, lavage, and brushings. During the clinical months, the fellow will learn to perform ultrasound-guided fine needle aspirations from cytology-boarded faculty.
