 SPUTUM PRETREATMENT SOLUTION |
|
| PURPOSE : |
| The SPUTUM PRETREATMENT SOLUTION is used for the concentration and inactivation of Mycobacterium tuberculosis (T.B.)/Acid Fast Bacilli in human sputum. |
| |
| PRINCIPLE : |
| I n the past , sputum specimen was directly used to make a direct smear for the stain of T.B. in the bacterial laboratory. The accuracy and discover was lower. Statistically, the discovery rate of positive specimens from direct smear was about 30-40%. Furthermore, during the procedure of heating step, T.B. in the positive sputum specimen will vapor into air. The vapor T.B. may infect the operator or people in the bacterial laboratory. |
| |
| ADVANTAGES : |
- Clear background : viscosity, epithelium cell and other bacterial became soluble.
- Inactivation : the infectious of T.B. was inactivated.
- High sensitivity : after concentration, the discovery rate increased.
- High specificity : no false negative was found.
