Abstract
The present invention is directed toward a cytology collection apparatus and a method for preparing a uniform monolayer of cells. The apparatus allows the rapid preparation from body fluids of a cytology monolayer with very few overlapping cells and with fewer contaminants than prior devices. The apparatus is in the form of an openable cell collection container which houses a filter for collection of cells when body fluid passes therethrough.
Claims21
A cytology collection apparatus comprising first and second detachable portions defining a chamber;
- first and second ports defining at least two flow paths through the chamber;
- and a porous arrangement having a collection site adapted to collect cells positioned across one of the fluid flow paths.
A method for collecting cells for cytology comprising the steps of:
- a) passing a biological fluid containing cells through a cytology collection apparatus which includes a porous arrangement having a collection site adapted to collect cells positioned across the fluid flow path;
- and
- b) depositing a monolayer of cells on the collection site.
