Abstract:
1. An assay device for measuring serum cholesterol associated with high-density lipoproteins (HDL) in a blood fluid sample containing lipoproteins other than HDLs of the type including a sample distribution array effective to distribute a blood fluid sample from a sample application region to one or more sample collection regions, the device comprising: a HDL test pad in which HDL concentration can be assayed being spaced apart from said array, said HDL test pad being affixed to a mounting means; and a reagent pad containing a binding reagent effective to selectively bind and remove non-HDLs from the fluid sample; wherein said HDL test pad and said reagent pad are joined by a bond selected from the group consisting of a heat formed bond and heat activated adhesive bond; wherein said mounting means are effective (i) to maintain the device in a sample-distribution position, wherein said joined HDL test pad and reagent pad are spaced apart from said array, and (ii) to transfer said device to a test position, whereby the joined HDL test pad and reagent pad are in contact with said array.
