1. An analytical element for the detection of albumin in a liquid sample,said element comprising a reagent zone which contains an albumin-active complex comprising a detectable species bound to a carrier;

  • said detectable species having a sufficiently high affinity for albumin that, when contacted with a liquid solution containing albumin, said detectable species separates from said albumin-active complex and becomes bound to albumin to form a complex comprising albumin and detectable species;

    whereby albumin can be detected by (a) the presence of detectable species bound to albumin, or (b) a reduction in the amount of detectable species in said albumin-active complex.
