MANUFACTURING INTERNAL CONTROL (AFB) SMEARS BY PHAS AND BAS TREATED SPUTUM SAMPLES

Abstract

Objective: Internal control smears were prepared using phenol ammonium sulfate (PhAS) and bleach ammonium sulfate (BAS) methods. Methods: A complete of 150 smears were prepared, 80 smears were stained, and two different technologists validated 60 smears. Results: Consistency was found to be true when compared with the quality consistency table for all grades in both methods, and M±2SD was within the boundaries. Conclusion: This study suggests that PhAS and BAS are alternate concentration methods for the preparation of internal control smears.
