Kurin® Blood Culture Collection Set

with the patented, FDA 510(k) cleared Kurin Lock specimen diversion device

A typical blood culture collection set provides skin microbes a direct line to the culture bottle, but not Kurin.

Seamlessly integrated into familiar blood culture collection sets, the Kurin Lock specimen diversion device addresses the skin contaminants that challenge hospital efforts to reduce false-positive blood cultures.

Standing guard between the venipuncture site and the culture bottle, the Kurin Lock diverts the initial blood specimen that may contain skin microbes from deep within the dermis. A clinically-relevant specimen then bypasses the contaminants locked within the device.

The problem with false-positive blood cultures

Determining whether a bloodstream infection exists is critical to the wellbeing of patients and the financial health of hospitals.

A blood culture test is the gold standard for identifying bacteremia.

Each year, millions of blood culture tests inform patient care decisions in the U.S. The majority will find no infection.1 But, of the cultures that test positive, almost 1/3 are false-positive results.

blood culture collection set: Positive

When blood cultures test positive—whether true or false—immediate action is taken to treat the patient with antibiotic therapy.

blood culture collection set: False Positive

Roughly 20% of the microbes present in skin reside deep in the dermis layer and may be drawn into blood samples.2 Without a way to avoid these microbes, hospitals have accepted high rates of seemingly unavoidable false positives—until now with the introduction of Kurin.
