Test Update: Cell Count with Differential, Body Fluid

Beginning Tuesday, January 4, 2022, Spectrum Health Laboratories will include an automated neutrophil (PMN) count on Cell Count with Differential, Body Fluid (LAB210) orders for peritoneal body fluids. This component will be displayed in Epic as an absolute PMN count, body fluid.

• The absolute PMN count in the peritoneal fluid is calculated by multiplying the total nucleated cell count by the percentage of PMNs in the differential.

• This calculation aids in the diagnosis of spontaneous bacterial peritonitis (SBP).

• The diagnosis of bacterial peritonitis is established by a positive peritoneal fluid bacterial culture and an elevated peritoneal fluid absolute PMN count (≥250 cells/uL).

• Epic will automatically calculate the absolute PMN count in peritoneal body fluids based on the manual differential data.

• This component ONLY calculates for Cell Count with Differentials (LAB210) on PERITONEAL BODY FLUIDS Continue Reading

Protein Electrophoresis Testing Update

In December, serum and urine protein electrophoresis testing will be simplified and standardized. The only testing available will be:

Protein electrophoresis, serum, IFE if indicated

Protein electrophoresis, random urine, do IFE if indicated

Protein electrophoresis, 24 hour urine, do IFE if indicated

In addition, on December 5, 2019, a new panel will be added which reflects expert recommendations for first line testing for monoclonal gammopathy, including plasma cell myeloma and most cases of amyloidosis, called “Monoclonal Gammopathy Screen”

Protein electrophoresis, serum, IFE if indicated

Kappa and lambda free light chains Continue Reading
