Clinical significance
  
The detection of microorganisms in a patient’s blood has diagnostic and prognostic importance.  Bacteria enter the blood from extravascular sites such as the genitourinary tract, respiratory tract, abscesses, surgical wound infections and other miscellaneous sites either directly or via the lymphatic vessels. When bacteria enter and/or multiply in the bloodstream at a rate that exceeds the capacity of the reticuloendothelial system to remove them, bacteraemia results.
 
Blood cultures are essential in the diagnosis and treatment of the etiologic agents of sepsis.  Bacterial sepsis constitutes one of the most serious infectious diseases and, therefore, the expeditious detection and identification of blood-borne bacterial pathogens is an important function of the diagnostic microbiology laboratory.
 
Three negative sets of blood cultures in the absence of antimicrobial therapy are usually sufficient to exclude the presence of bacteraemia. One set is seldom ever sufficient.  Prior antibiotic therapy may cause negative blood cultures or delayed growth.
 
The BacT/ALERT® 3D Microbial Detection System is used to detect the presence of microorganisms in blood of patients suspected of having bacteremia.  The BacT/ALERT 3D System and supporting media provide a complete system for microbial detection and growth requirements.  The media provides optimal nutritional requirements for organisms commonly found in blood infections, while the instrument provides the environmental conditions needed for growth.  Inoculated bottles are placed into the instrument where they are continuously monitored for the detection of microbial growth.  

We will be happy to answer any questions that you might have.
