Claims6
A solid-support for use in simultaneously assaying for a blood serum-derived test substance and a blood serum-derived marker substance in oral fluid wherein the marker is always present in oral fluid comprising:
- a first region to which is attached a first binding agent effective to bind specifically to a blood serum-derived test substance in oral fluid;
- a second region to which is attached a second binding agent effective to bind specifically to a blood serum-derived marker substance in such oral fluid;
- means for visualizing test substance bound to said first region;
- and
- means for visualizing marker substance bound to said second region;
- whereby oral fluid containing the marker substance and not the test substance gives rise to a pattern on the solid-support surface that is distinguishable from a pattern that appears for oral fluid containing both the marker substance and the test substance.
