Claim 8:
9. The apparatus of claim 1, wherein the blood collection module is sealed to the skin around the collection site with a vertical orientation in which the proximal portion of the blood collection module is oriented above the distal portion of the blood collection module when the transfer module being is coupled to the angled transfer port of the blood collection module from a direction lower than the collection site to facilitate self-venting,
wherein, in the vertical orientation, a portion of the non-microfluidic blood flow channel defined by an interior surface of the angled transfer port comprises:
a gravity-assisted blood flow path along a sub-portion of the non-microfluidic blood flow channel to which the blood is pulled by gravity; and
a self-venting return path for air above the gravity-assisted blood flow path.
