Kurin Blood Culture Collection Sets

Clinically proven and FDA indicated for reducing blood culture contamination.*

Kurin Lock^® blood culture collection sets passively sideline the initial 0.15ml of blood, which may contain contaminants from the patient’s own skin, ensuring that the best possible blood specimen reaches the collection bottles.

Studies show compliance with best practice combined with Kurin technology to sideline the initial flash of blood can reduce contaminated cultures by more than 80%, improving the clinical value of blood culture testing for safer, more effective, and lower cost treatment of patients.

Battling false-positive blood cultures

Bloodstream infection diagnosis is critical to the wellbeing of patients and the financial health of hospitals.

Each year, millions of blood culture tests occur, though the majority will find no infection.¹ Of the cultures that test positive, almost 33% are FALSE-positive results caused by contamination.

Roughly 20% of the skin microbes reside deep in the dermis layer and may be drawn into blood samples.² Unavoidable until now, hospitals have accepted the consequences of high rates of false positive results.

Just like the boy who cried wolf, high numbers of false positive results lead to inappropriate treatment and cause physicians to question the test. Hear experts explain the consequences of blood culture contamination.

Centers for Disease Control and Prevention

In offering guidance, the CDC references a study by Doern et al which identifies ways to address blood culture contamination. Among the preventive actions, the CDC authors call for the use of diversion devices saying, “There are devices that are commercially available that have shown promise in further reducing blood culture contamination rates. These devices initially divert a small amount of potentially contaminated blood and then collect blood for the blood culture.”

*The Kurin Blood Collection System is for use as a blood collection system and its Kurin Lock allows the specimen of blood from the patient to be sidelined prior to the collection of the test sample to reduce the frequency of blood culture contamination when contaminates are present in the initial blood sample compared to blood cultures drawn using standard practice without the Kurin Lock.
