A fluid sample collection card comprising:
- an absorbent strip including a sample application portion, a first absorbent strip portion extending directly from the sample application portion, and a second absorbent strip portion extending directly from the sample application portion and spaced apart from the first absorbent strip portion by the sample application portion;
- a non-absorbent layer positioned beneath the absorbent strip;
- and
- a sample application portion indicium configured to identify the sample application portion.
A method of collecting a fluid sample comprising:
- identifying a sample application portion of an absorbent strip of a collection card using a sample application portion indicium;
- applying a volume of fluid onto the sample application portion of the absorbent strip;
- moving a first portion of the applied volume of fluid along a first absorbent strip portion extending directly from the sample application portion and positioned on a nonabsorbent layer of the collection card;
- and
- moving a second portion of the applied volume of fluid along a second absorbent strip portion extending directly from the sample application portion and positioned on the nonabsorbent layer, wherein the second absorbent strip portion is spaced apart from the first absorbent strip portion by the sample application portion.
A method of obtaining a plurality of separated components of a fluid sample comprising:
- receiving a collection card with an absorbent strip positioned on a nonabsorbent layer;
- identifying a first absorbent strip portion on a first side of an identified sample receiving portion of the absorbent strip and spaced apart from the identified sample receiving portion, the first absorbent strip portion including a first separated component of a fluid sample;
- detaching the identified first absorbent strip portion from the absorbent strip;
- identifying a second absorbent strip portion on a second side of the identified sample receiving portion of the absorbent strip and spaced apart from the identified sample receiving portion, the second absorbent strip portion spaced apart from the first absorbent strip portion by the sample application portion, the second absorbent strip portion including a second separated component of the fluid sample;
- and
- detaching the identified second absorbent strip portion from the absorbent strip.
