Identification of Common Bacterial Pathogens Causing Meningitis in Culture-Negative Cerebrospinal Fluid Samples Using Real-Time Polymerase Chain Reaction

Table 4

Comparison between real-time PCR positive and negative samples as regards CSF cells and chemistry results.

Variables	RT-PCR positive	RT-PCR negative	/	p value
	Median
Protein (mg/dL)	300	102.5	−1.873	0.061 (NS)
Glucose (mg/dL)	17	21.5	−0.339	0.735 (NS)
WBCs (total/mm^3)	2215	400	−1.579	0.114 (NS)
	Mean ± SD
Neutrophil percentage	75 ± 21.8	67.5 ± 18.5	0.66	0.513 (NS)

Data are presented as median or mean ± standard deviation.
NS: nonsignificant result ( value > 0.05).
: Mann-Whitney test.
: unpaired -test.
WBCs, white blood cells.
