GS184-2

Posted on by CMPT

Gram – CSF: 3+ (6-10/oif) lymphocytes; 3+ (11-50/oif), no bacteria – Shipped February 11, 2019

HISTORY

A simulated CSF sample from an 18 year old with severe headache in ER was sent to category A, C, and C1 laboratories.

 

MAIN EDUCATIONAL POINTS from GS184-2

  1. It is important that laboratories correctly differentiate and report the predominant WBC type as this assists in identifying the most likely etiologic agent.
  2. If laboratories are unable to distinguish between polymorphonuclear and mononuclear cells on Gram stain, then they should report as white blood cells (WBCs) without type differentiation.
