Improved Diagnosis of Pulmonary Tuberculosis using bleach Microscopy Method.

Background: The bacteriological diagnosis of tuberculosis (TB) is largely dependent on the Ziehl-Neelsen (ZN) microscopy. This method has a low sensitivity, which can be improved by the concentration of the specimen with sodium hypochlorite (NaoCl), followed by centrifugation before doing acid fast staining (AFB).

Aim: To study the improvement in the sensitivity of the sputum smear by the bleach method.

Comparative study of peripheral blood smear and quantitative buffy coat in malaria diagnosis.

A rapid test for diagnosis of malaria based on acridine orange staining of centrifuged blood samples in a microhaematocrit tube (QBC) was compared with Leishman stained thin peripheral blood smear in 287 samples. Malaria was diagnosed in 44 patients by Leishman staining technique and in 65 patients by QBC method. The QBC method allowed detection of an additional 21 cases.
