Doctors are looking for faster and more efficient systems for the
diagnosis of infectious diseases in order to start treatment at
the earliest for better patient management. One example of an infectious
disease is tuberculosis where early treatment is critical to prevent:
|
The spread of diseases in the community |
|
The emergence of multi
drug resistant tuberculosis |
Keeping this concern of doctors in mind, our laboratory has introduced
BACTEC 460 TB, which is a rapid system for automated detection,
susceptibility testing and differentiation on mycobacterium.
Though there are myriads of diagnostic tools available for the diagnosis
of TB, culture is always considered as a "Gold Standard".
The biggest draw back for the conventional LJ culture method is
the time factor. It takes approximately 5-6 weeks just to know whether
the sample is positive or negative. The above disadvantage has been
overcome by the BACTEC 460 TB system in laboratories, which saves
practically 30-50 days when compared with the LJ culture.
BACTEC 460 has not only increased the rapidity and sensitivity of
the culture system but has also introduced very reliable and standardized
methods for differentiation and drug sensitivity, which is very
important in the proper management of the patient.
