Gram – CSF: no/few white blood cells, no bacteria, and red blood cells – Shipped February 2014
A simulated cerebrospinal fluid (CSF) smear collected from a 36 year old patient with severe headache was sent to category A, B, C, and C1 laboratories for Gram staining.
Participants were expected to report the ab-sence of (or few) neutrophils and no bacteria. Quantifying red blood cells (RBCs), when present, may provide additional information to clinicians.
