Automated Bld Cult
Question | Answer |
---|---|
Which automated blood culturing system utilizes fluorescence to detect CO2? | BACTEC FX |
What kind of detector does the BACTEC FX have? | A photodiode detector |
What is the method of detection for the Bac-T alert system? | A colorimeter senses increasing CO2 |
Which automated system detects headspace pressure from all types of gases? | Versa-Trek |
What makes a blood culture system fully automated vs semi-automated? | Semi-automated systems require the blood to be incubated first and then the machine will read the culture. Fully automated systems continuously monitor over 5 days. |
What kind of device is used to read the CO2 in the Bactec HPS NR 660? | An infrared spectrophotometer |
What is the principle of the Bactec 460 and what is it mainly used to detect? | It measures a radioactive isotope of C14 on glucose - as glucose is metabolized, CO2 tagged with C14 is released; mainly used for Mycobacterium tuberculosis |
