Diagnostic Yield of Fluorescence and Ziehl-Neelsen Staining Techniques in the Diagnosis of Pulmonary Tuberculosis: A Comparative Study in a District Health Facility

Table 5

Comparison of diagnostic yield of “spot” and “early morning” sputum samples.

Spot	EM		Kappa	P value
	Positive	Negative
Fluorescence
Positive	34(91.8)	0(0.0)	0.935	p≤0.001
Negative	3(8.1)	63(100.0)
ZN
Positive	21(84.0)	0(0.0)	0.887	p≤0.001
Negative	4(16.0)	75(100.0)

Data is represented in raw figures and percentages. P-value is statistically significant if p< 0.05 as compared between “spot” and “early morning (EM)” sputum samples. EM: early morning.
