Hologic (Thinprep Method)
•Bloody and mucoid samples are problematic
•Increased Unsatisfactory Rate
•Special Expensive filter
•T-2000- Slow, High Labor, No Sample ID
•Collection device cannot be left in vial
•Toxic Preservative
![Page 18: CellSolutions Evolution€¦ · BD FocalPoint GS ThinPrep Imager Scalability Low to High Volume (3DHistech Scanners) Medium Medium Throughput (per slide) ~1 minute (Flash III) ~5-6](https://reader033.vdocuments.us/reader033/viewer/2022060703/607013281747716260431ac6/html5/thumbnails/18.jpg)
Thinprep’s Blood Problem
• 76% squamous cancers and 60% of adeno cancers
“many” to “abundant” Precipitated Hemoglobin
• “….current results support previous findings that bloody
hypocellular ThinPrep slides can harbor significant
lesions.”

BD (Surepath Method)
•Excessive front-end processing
•No positive sample identification
•Staining on processor has limited color range
•Expensive settling chambers & syringes
•Cell presentation appears “crowded” and three-
dimensional- hard to screen and scan
