The test card of claim 1, wherein the average fluid channel network distance between wells is from about 20 to about 25 mm. 7. The test card of claim 1, wherein the fluid channel network further comprises a second distribution channel disposed on said first surface of said test card and operatively connected to a second set of sample wells. 8. The test card of claim 7, wherein the fluid channel network further comprises a third distribution channel, a plurality of third fill channels and a plurality of through-channels disposed on said first and said second surface of said test card and operatively connected to a third set of sample wells. 9. The test card of claim 8, wherein the fluid channel network further comprises a fourth distribution channel, a plurality of fourth fill channels and a plurality of through-channels disposed on said first and said second surface of said test card and operatively connected to a fourth set of sample wells. 10. The test card of claim 9, wherein the fluid channel network comprises a fifth distribution channel and a plurality of fifth fill channels disposed on said first surface of said test card and operatively connected to a fifth set of sample wells. 11. The test card of claim 1, further comprising sensor stop holes for aligning the card for optical readings. 12. The test card of claim 11, wherein said sensor stop holes are aligned from about 0.25 mm to about 2 mm ahead of each of said columns of sample wells. 13. The test card of claim 1, wherein the average fluid channel network distance between wells is less than 30 mm. 14. The test card of claim 1, wherein the plurality of fill ports are perpendicular to the at least one distribution channel. 15. The test card of claim 1, wherein the first fill channels are perpendicular to the at least one distribution channel at a junction between the first fill channels and the at least one distribution channel. 16. The test card of claim 1, wherein the widthwise direction is defined parallel to a longest edge of the card body, and wherein each of the fill ports is oriented parallel to the longest edge of the card body. 17. The test card of claim 1, wherein the fill ports terminate at respective ones of the sample wells. 18. The test card of claim 1, wherein said test card comprises from about 80 to about 140 total sample wells.
