SMILLER Posted April 21, 2011 Share Posted April 21, 2011 Years ago we dropped reporting % differentials on our CBCs. The idea being that absolute counts are more significant if elevated or lowered. There is still some contention here among the techs as to whether %s should be still be used to screen for slide review (eg, high lymphs to be screened for reactive or atypical morphology).Do any other labs still report or otherwise make decisions based on % counts for automated diffs?

Deny Morlino Posted April 21, 2011 Share Posted April 21, 2011 We still report the %, but decisions are based on both absolute and % numbers. There are flags set for each parameter individually. Link to comment Share on other sites More sharing options...
Bill Posted April 21, 2011 Share Posted April 21, 2011 We report both but all decisions for manual diff are absolute count based. Link to comment Share on other sites More sharing options...
Steven Jeff Posted April 22, 2011 Share Posted April 22, 2011 We have only reported absolute counts for the last 15 years and therefore all decisions are made on themSteve:) Link to comment Share on other sites More sharing options...
silverblood Posted April 25, 2011 Share Posted April 25, 2011 At my hospital we report both % and absolute numbers for differentials-seems most of the Dr's are still more familiar with %-except for maybe the oncology Drs who look for the ANC when they are giving chemo. we do not rep[ort out an ANC-they have to derive that themselves......

pkress Posted May 16, 2011 Share Posted May 16, 2011 We report both but use the absolute counts for decisions on manual differentials and path review. Link to comment Share on other sites More sharing options...

melraek23 Posted May 30, 2011 Share Posted May 30, 2011 The facility I work in just started up not to long ago and the doctors decided to report out only the %'s. This is different than other places I have worked but it is what the doctor's preferred here. Link to comment Share on other sites More sharing options...

Joseph Posted August 5, 2011 Share Posted August 5, 2011 We report absolute and relative values on our automated diffs. The manual diff are reported in % only because that's the way it been done for years. Most docs like the % because they can remember the reference ranges and the relationship, ie: 70/30, 60/40. Our decision rules to perform a manual are based on the absolute values provided the cell populations are in typical positions. I personally don't believe that you should calculate absolute values for a manual diff based on only 100 counted cells. Jusy my "professional" opinion. I also find it interesting the most of our docs and nurses don't know how to calculate the ANC. eric1980 1 Link to comment Share on other sites More sharing options...
Soraya Ocasio Posted October 2, 2011 Share Posted October 2, 2011 When you perform a manual diff, did you calculate y the absolute nomber fro abnormal cells 1.e. bands, var lymph metamyelo, blast ect...???We have only reported absolute counts for the last 15 years and therefore all decisions are made on themSteve:) Link to comment Share on other sites More sharing options...

Jusy my "professional" opinion.Hi JosephAnd when you issue a percentage based report, how many cells do you count then?

Steven Jeff Posted October 3, 2011 Share Posted October 3, 2011 You calculate the absolute numbers from the total WBC i.e. if there are 6% blasts then the absolute number is 6% of the total WBCSteve Link to comment Share on other sites More sharing options...
eric1980 Posted January 7, 2012 Share Posted January 7, 2012 The LH750 in my lab reports both sets of parameters anyway. So we report them both.We report abs# for manual differential using the LIS. It's calculated automatically when we key in the %. Link to comment Share on other sites More sharing options...
