I’ve had 3 Livers USG- FNB nondiagnostic. All cats with diffuse Hyperechoic liver that I’ve suspected Hep. Lipidosis vs Lymphoma/other. I do look at microscope to assure samples good enough to send. All these samples have only blood on it with very few to no hepatocytes. I’m using a 23 G 1.5 inch attached to a seringe.I don’t aspirate just move the needle back and forth fast 7-8 times. Suspect I have to change something….Any suggestions?
