Comparison of blood-culture contamination rates in a pediatric emergency room: newly inserted intravenous catheters versus venipuncture

Infect Control Hosp Epidemiol. 2000 Oct;21(10):649-51. doi: 10.1086/501708.


We compared contamination rates of blood cultures obtained either from newly inserted intravenous catheters or via venipuncture. Of 2,431 blood cultures, the overall contamination rate was 2.7% (intravenous catheter, 3.4%; venipuncture, 2.0%; P=.043). The site of lowest contamination was the antecubital fossa, making this the optimal choice for blood-culture sampling.
