Rapid test for urine albumin and urine creatinine

A device for determining an albumin-creatinine-ratio in a human sample comprising:

• a test cassette comprising a test strip, wherein the test strip comprises;
• a single sample application pad containing a sample well disposed on the solid support;
• a conjugate pad having disposed therein a creatinine-specific conjugate and an albumin-specific conjugate;
• a lateral flow membrane;
• a creatinine-specific test region in which creatinine present in a sample and bound to the creatinine-specific conjugate is retained by a creatinine-specific immobilization agent associated with the membrane;
• a creatinine-specific control region in which the creatinine-specific conjugate which is not retained by the creatinine-specific test region is retained by a creatinine conjugate-specific immobilization agent associated with the membrane;
• an albumin-specific test region in which albumin present in the sample and bound to the albumin-specific conjugate is retained by an albumin-specific immobilization agent associated with the membrane;
• an albumin-specific control region in which the albumin-specific conjugate which is not retained by the albumin-specific test region is retained by an albumin conjugate-specific immobilization agent associated with the membrane;
• a reservoir;
• a measurement device to determine the concentration of albumin in the sample, the concentration of creatinine in the sample, and the albumin-creatinine-ratio.
