Abstract: A fluid sample collection card assembly in one embodiment is assembled by forming a tray assembly by supporting an absorbent layer configured to receive a fluid sample on a base portion, the base portion including a tray portion, by positioning the absorbent layer on an upper surface of a holder portion of the tray portion, the holder portion located beneath an upper surface of the tray portion, removably inserting the formed tray assembly into a tray assembly receiving cavity of a case through a mouth portion of the case, and closing, at least substantially, the mouth portion of the case with a faceplate portion of the base portion.

Abstract: A fluid sample collection card in one embodiment includes 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.

Abstract: A fluid sample collection card assembly in one embodiment includes a case including a tray assembly receiving cavity accessible through a mouth portion of the case, and a tray assembly, the tray assembly including an absorbent layer supported by a base portion, the base portion including (i) a tray portion configured to be removably received within the tray assembly receiving cavity and (ii) a faceplate portion configured to at least substantially close the mouth when the tray portion is received within the tray assembly receiving cavity.

Abstract: A method of making a fluid sample collection card includes providing a support layer, forming an upper layer with a card stock, the upper layer including a sample window and a viewing window, supporting an absorbent layer with the support layer, and positioning the upper layer on the absorbent layer, wherein the upper layer is configured such that as a fluid is being absorbed by the first absorbent layer portion, presence of a portion of the fluid within the second absorbent layer portion indicates that a first volume of the fluid absorbed by the absorbent layer is a minimum necessary volume of the fluid sufficient to perform at least one test on at least one component in the fluid.
