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
When a Cerebrospinal fluid (CSF) specimen arrives into the laboratory and is deemed Quantity Not Sufficient (QNS) for ordered testing, the ordering provider is contacted to identify testing priorities. Occasionally, the laboratory is unable to secure these priorities.
If the lab is unable to secure priorities from the ordering provider within an hour of collection, the following will occur:
1. We will move forward with the Cell count with differential, Culture, and Protein/Glucose
2. The rest of the ordered testing will hold until we can clarify the priorities
Laboratory is partnering with Epic Beaker to discover if a prioritization of orders, upon CSF order entry, is possible.

Effective February 24, 2021, Cerebrospinal Fluid (CSF) Xanthochromia results of “Present” will be considered a critical laboratory value.
This change was approved by the MEC and driven by a collaboration between neurology and laboratory departments to assist in expediting the diagnosis and management of patients with possible subarachnoid hemorrhage (SAH).
