Claim 12:
13. A point-of-care biosensor for measuring albumin to creatinine ratio (ACR) in a biological sample, said biosensor comprising:
(i) a housing with a display member and an electrically conducting port,
(ii) the device as claimed in claim 1, disposed to connect to said housing through said electrically conductive port for collecting and retaining a biological sample; and
(iii) a digital controller disposed in said housing and configured to measure redox currents of urine creatinine and urine albumin from a redox potential applied to said device, to calculate albumin to creatinine ratio in said urine sample and render albumin to creatinine ratio (ACR) by linearly matching the concentrations of urine creatinine and urine albumin with corresponding redox currents;
(iv) a database member with stored standard values of urine creatinine and urine albumin bioanalyte concentrations in urine samples along with reciprocal redox currents, connected to said digital controller.
