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

New Test: Thrombin Time

Effective March 4th, 2020, Thrombin Time will change from a sendout reference test performed by Mayo Clinic Laboratories to an in-house test performed by Spectrum Health Regional Laboratory. This test will be performed in the Coagulation Laboratory and will include a new reference range (please see link in Test Information below).

Thrombin Time is suitable for monitoring fibrinolysis therapy, screening for disorders of fibrin formation and in cases of suspected fibrinogen deficiency states. It is also useful for the differentiation between a heparin induced prolongation of the thrombin time and fibrin formation disorders.

For questions around this test, please contact the Coagulation Department at 616-267-2740.

TEST INFORMATION

Thrombin Time – Epic Code: #LAB11230581, Interface Code: #11230581, CPT: #85670
