Analysis of the performance of external quality assurance of tuberculosis sputum smear microscopy at medical institutions in Chaoyang district,Beijing

To develop new methods for estimating the sputum smear-positive tuberculosis case detection rate (CDR) in a country where infection with HIV is prevalent.

Results: with current cost, local QC rate reached 100%, about 60% sputum smears of newly registered tuberculosis patients were supervised under QC system every year.

The system could also diagnose sickle-cell anaemia from blood samples, while fluorescent images of a stained sputum smear were sufficient to identify the presence of tuberculosis.

Only about 2.2 million TB cases annually are diagnosed and reported with sputum smear microscopy, the most widely available test.

TB was asymptomatic in 18 culture-positive individuals, 8 of whom (4 in each HIV status group) had positive sputum smears.
