What is a bactec blood culture?
The BD BACTEC™ Automated Blood Culture System utilizes fluorescent technology in detecting the growth of organisms in the blood culture bottles. The sample to be tested is inoculated into one or more vials which are inserted into the BD Bactec fluorescent series instrument for incubation and periodic reading.
How does a blood culture machine work?
These systems, such as the BACTEC, BacT/ALERT and VersaTrek, consist of an incubator in which the culture bottles are continuously mixed. Growth is detected by sensors that measure the levels of gases inside the bottle—most commonly carbon dioxide—which serve as an indicator of microbial metabolism.
What is BD bactec plus anaerobic F culture vials?
INTENDED USE The BD BACTECT Plus Anaerobic/F medium is used in a qualitative procedure for the anaerobic culture and recovery of microorganisms (bacteria) from blood. Increases in the fluorescence of the vial sensor caused by the higher amount of CO2 are monitored by the BD BACTEC fluorescent series instrument.
What is sodium Polyanethol sulfonate?
