Abstract:
An improvement to the analysis of a sample of urine for the concentration of albumin using the concentration of creatinine to correct the concentration of albumin which improvement comprises:a) determining the observed concentrations of albumin and creatinine using a semi-quantitative analytical procedure for each;b) determining if the observed concentration of albumin and creatinine are inside or outside threshold limits which are within the dynamic ranges of the semiquantitative analytical procedures;c) if the observed concentrations of albumin and creatinine are outside the threshold limits, then assigning the threshold limits closest to the observed value as the observed concentrations;d) if the observed value of the creatinine is the same as a threshold limit, then indicating an improper specimen which is discarded; ore) if the value of the albumin is the same as a threshold limit, then assigning a ratio value by dividing the threshold limit of the albumin by a value representing the normal clinical concentration of the creatinine.
