Department of Pathology, Wentworth Douglas Hospital, Dover, NH 03820, USA
Arch Pathol Lab Med 128:621-6. 2004..The laboratory test turnaround times (TATs) that exceed the expectations of clinicians who order those tests, the so-called outlier test reporting rates, may be responsible for perceptions of inadequate laboratory service...

Department of Pathology, University Hospital of Brooklyn, Brooklyn, NY, USA
Arch Pathol Lab Med 130:828-30. 2006..Total serum calcium commonly is included in critical results lists; however, a wide range of values are used and there is scant outcome data justifying inclusion of this analyte in these lists...
