Table 4. Comparisons of microscopic cytomorphological features and FNA gross appearance with Xpert test and CRS (culture and/or ZN).

		Xpert	CRS (culture and/or ZN)
FNA cytology result	Total (N)	Positive %(n/N)	Positive %(n/N)
TBL	96	74%(71/96)	77% (74/96)
Chronic inflammation	16	18.8%(3/16)	43.8%(7/16)
Suppurative abscess	15	66.7%(10/15)	66.7%(10/15)
Reactive lymphadenitis	11	9%(1/11)	0
Malignancy	5	20%(1/5)	20%(1/5)
Gross FNA appearance
Purulent	73	56.2%(41/73)	60.3%(44/73)
Caseous	58	69%(40/58)	72.4%(42/58)
Bloody stained	12	41.7%(5/12)	50%(6/12)

TBL = tuberculous lymphadenitis, FNA = fine needle aspirate, CRS = composite reference standard, ZN = Ziehl-Neelsen.
