We are looking at performing quantitation of D positive cells (FMH) by flow cytometry.  I have been trialing Fluro-D (FITC labelled, CSL product) using the method as recommended by the manufacturer.  So far I have found that my standard curve results (O Neg blood spiked with O Pos blood) don't always correlate as close as I would expect/like.  Is this due to poor technique or have other operators found similar results.  So far, I have been able to detect low levels of D positive cells with minimal background. However, I would appreciate any comments from other users about potential pitfalls, correlation to Kleihauer results, best method of reporting (% or mls of D cells) and any other general hints.
Thanks to all replies,
Wanda
