Valid Article
BLOOD CULTURE, BacT/ALERT Adult (FA)
CAUTION
This test is worded and codified by unit to make the order easier, but it is always packaged in kit of 100.
Definition
BacT/ALERT® FA Plus Culture Bottles are used with the BacT/ALERT® Microbial Detection System in qualitative procedures for recovery and detection of aerobic and facultative anaerobic microorganisms (bacteria and yeast) from blood and other normally sterile body fluids.
Specifications
BACT/ALERT® Microbial Detection Systems utilize a colorimetric sensor and reflected light to monitor the presence and production of carbon dioxide (CO2) dissolved in the culture medium.
If microorganisms are present in the test sample, carbon dioxide is produced as the organisms metabolize the substrates in the culture medium. When growth of the microorganisms produces CO2, the color of the gas-permeable sensor installed in the bottom of each culture bottle changes from blue-green to yellow. The lighter color results in an increase of reflectance units monitored by the system. Bottle reflectance is monitored and recorded by the instrument every 10 minutes.
Components
Each bottle contains 30 mL of supplemented complex medium and ≥1.6 g adsorbent polymeric beads.
At time of manufacture, the medium consists of the following reactive components:
- combination of peptones/biological extracts (≥1.85% w/v),
- anticoagulant (≥0.083% w/v),
- vitamins and amino acids (≥0.00145% w/v)
- carbon sources (≥0.45% w/v),
- trace elements (≥0.0005% w/v).
- other complex amino acid and carbohydrate substrates in purified water.
Bottles contain an atmosphere of N2, O2, and CO2, under vacuum.
Technical specifications
- BACT/ALERT® culture bottles contain polycarbonate. Not all disinfectants are intended for use with polycarbonate surfaces and may cause bottle deterioration.
- Volume of blood to be added: 10 ml
- Colour-coded: pale green
Packaging & Labelling
Kit composed of 100 culture bottles containing 30 ml of culture medium each.
