1. A method of using a sample procurement device to obtain a blood sample from a patient with reduced contamination to reduce false results in culture testing of the blood sample, the sample procurement device defining a first fluid flow path and a second fluid flow path and having a junction, the method comprising:

  • establishing fluid communication with the vasculature of the patient;

    receiving a first volume of blood from the patient into the first fluid flow path when the junction is in a first state;

    the junction configured to transition to a second state as a result of receiving the first volume of blood from the patient such that a portion of the first volume of blood is sequestered in the first fluid flow path; and

    receiving a second volume of blood into a sample vessel via the second fluid flow path, the sample vessel containing a culture media,whereby sequestering the portion of the first volume of blood sequesters contaminants present in the first volume of blood, thereby reducing contamination in the second volume of blood used as the blood sample in the culture testing.
