Results of culture, AFB smear, histology, cytology, and PCR analysis for 45 patients with lymphadenitis
| Number of patients positive/number of patients tested (%) | |||
|---|---|---|---|
| Method* | TBLN (n = 22) | NTL (n = 14) | GLA (n = 9) |
| *Results of biopsy and FNA have been combined. | |||
| p < 0.0002 for PCR v culture; Mycobacterium tuberculosis was cultured from biopsy and FNA in one patient only. | |||
| p < 0.005 for PCR v AFB smear, AFB were detected in biopsy and FNA in one patient only. | |||
| AFB, acid fast bacilli; FNA, fine needle aspirate; GLA, granulomatous lymphadenitis; NTL, non-tubercular lymphadenitis; PCR, polymerase chain reaction; TBLN, tuberculous lymphadenitis. | |||
