How to perform fine needle aspirates
Katherine Beard · The Veterinary Nurse · 2014
Fine needle aspirates (commonly referred to as FNAs) are common diagnostic tools performed to obtain cytological information that could help aid in diagnosing veterinary patients. They can be performed on external or internal masses, or lymph nodes. Since veterinary nurses can perform FNAs on external masses and lymph nodes, it important for them to understand how to perform them correctly so a diagnostic sample can be obtained. This article will focus on two different methods of performing FNAs, and how to prepare the sample on microscope slides that will be used to obtain cellular information.
