The challenge of preventing blood culture contamination
Why is preventing blood culture contamination so challenging?
While training and education can help, it will not effectively solve the challenge of contamination. Blood culture contamination happens easily and often due to these common factors:
Alternative Diversion Methods
Other techniques and methods have been attempted, but they all fall short.
Manual Diversion Limitations
Passive Diversion Device Limitations
When it comes to diversion effectiveness, volume matters.
Less than 0.5mL
Diverting less than 0.5mL of blood has not proven to be effective for significant reductions in blood culture contamination.1,3
The most practical and effective volume based on independent clinical studies to reduce blood culture contamination.¹
2.0mL or more
Diminishing contamination reduction improvement when drawing over 2mL of blood.¹

Meet Dr. Patton,
The founding father of initial specimen diversion for blood cultures
In 2006, Dr. Patton designed a clinical study to test the effectiveness of Initial Specimen Diversion Technique (ISDT™), an innovation that he conceived earlier in his career. The results of the study were the basis for the seminal study on initial specimen diversion, published in the Journal of Clinical Microbiology.
Dr. Patton patented initial specimen diversion for blood culture collection, both the technique, ISDT™, and the technology, ISDD®. His mission in co-founding Magnolia Medical Technologies was to eliminate the patient harm resulting from unnecessary antibiotic treatment due to false-positive blood cultures.
