It is interesting how difficult it is to find documented evidence of CLIA's Cytology Quality Controls of "screening" more than 100 slides/8hrs/day and counting liquid-base sides as 1/2 a slide.

On the top/right of screen find SEARCH box and enter 00016177 then find "Regs for Implementing the Clinical Laboratory..." scroll down to "Cytology Quality Control"
This is the first time I've seen reference to 1/2 slides for liquid-base gyn cytology and making up to 200slides/8hr/day.
The date of this document is ambiguous (to me) and seems to be 8/5/98.
I do not agree with this assessment of 200slides/8hr/day but there it is ...
