The dark art of blood cultures

Understanding the diagnostic methods necessary to identify bloodstream infections.

In the clinical microbiology laboratory, blood is a critical diagnostic sample that, in the majority of cases is sterile (or is it?).

However, when microbes gain access to and multiply in the bloodstream, it can result in life-threatening illness including sepsis.

Mortality rates from bloodstream infection and sepsis range from 25% to 80%, killing millions of people annually.

Blood cultures are a vital technology used in the microbiology laboratory to isolate and identify microbes and predict their response to antimicrobial therapy.

This title surveys the entire field of blood culture technology, providing valuable information about every phase of the process, from drawing samples to culture methods to processing positive cultures.
