A test sample card has a fluid passage network provided on both sides of the card to provide for maximum separation distance between adjacent growth wells. The card also has cored sections along its periphery adjacent the wells, which improve the flow of plastic during the molding of the cards. The cored sections control the formation of knit lines in the surface of the card and eliminate knit lines from forming that could potentially bridge adjacent wells. These features, singly and together, combine to produce a card that is essentially immune to cross-talk between adjacent wells, yet permit a greater number of wells in a card of given dimensions. Improved bubble trap features are also provided for the card, including a bubble trap passage having a restriction formed therein. The restriction prevents air bubbles in the bubble trap from migrating back to the growth wells.

[ We claim:] [1.] A test sample card having a body made from a molded material, said body comprising a fluid entrance port and first and second end regions and first and second side regions, said body defining a plurality of wells placed between said first and second end regions and said first and second side regions, said body further comprising a fluid passage network connecting said fluid entrance port to said wells,the improvement comprising:said body having cored regions comprising depressions in said body formed by positive elements in a mold forming said body, said cored regions disposed in at least one of said first and second end regions and said first and second side regions in a predetermined relationship to said wells so as to control the formation and direction of knit lines in the surface of said card relative to said wells,said cored regions improving the flow of said molded material during molding of said card in said mold to thereby control the formation of said knit lines in said material.
