POC Hemoglobin Testing in OR/SDU

We too use the Hemocue 201 DM. I have never had a complaint about the TAT. Are you familiar with STAT mode? You place the cuvette in the analyzer first and then program it. By the time you finish programming, you generally have the result. I have noticed that the timing is based on the hgb value: low is quicker than higher values. It correlates ok when we run correlations, but you cannot rule out preanalytical issues and how the sample is actually placed in the cuvette (hydrophobic surface vs direct feed from finger or syringe, which of course is the incorrect way of doing it).
This is making it sound like I like the meter, I don't. It doesn't like me either. Most OR staff use the ISTAT for H/H. We have a few that hold out for the Hemocue (but it is rarely used by them), I think because it is quicker than the ISTAT.

Michael, I can't speak for testing in OR/SDU, I only use in ambulatory/clinic space (may be irrelevant for you in terms of hospital/IFU/connectivity options). 
We switched to the Hemocue 801 a few years ago from Hemocue 201 for limited use (Pediatric and Medicine Specialties clinics). MDs/RNs like the 'less than 1 second' speed, and supervisors appreciate the longer microcuvette shelf life.

We use the same analyzer in our Infusion center.  In the past, the staff complained about a discrepancy when compared the CBC result from the lab and the hemocue. After spending time with the users, I found that sometimes they were not testing the samples within 10 minutes as the manufacturer recommends, and cleaning was not always done after each day of use. 
The collection technique may be a factor for discrepancies.
For the Hemocue 201DM validation, all the twenty patient results correlated very closely with the Hematology analyzer in the main hospital, we are confident 
No complaints about the TAT.
