Hemagglutination - what does it look like?

L

Does anyone else use hemagglutination experiments to detect lectin activity? What does agglutination of red blood cells actually look like down a microscope. My samples lyse live blood cells so i have had to fix the blood (with glutaraldehyde). But once the bloods fixed its really hard to tell whether its pelleted or formed a veil. So I've been trying to look at it on an inverted microscope to be able to tell....
