Abstract:
1. A method of obtaining a blood sample from a patient, the method comprising: inserting a first needle into the patient; inserting into a pre-sample reservoir a second needle fluidically coupleable to the first needle; receiving a first volume of blood into the pre-sample reservoir, the first volume of blood in the range of 1 ml to 5 ml; after the first volume of blood has been received into the pre-sample reservoir, removing the second needle from the pre-sample reservoir; inserting the second needle into a first sample vessel containing at least one of aerobic culture media and anaerobic culture media; and receiving a second volume of blood into the first sample vessel, whereby receiving the first volume of blood into the pre-sample reservoir reduces false positives in culture tests of the second volume of blood.
