Feasibility Study of Spectral Detection Bovine Serum Albumin

The optical spectrum detection method of albumin proposed in this study can help patients find proteinuria problems in the early stage, which can be detected in the early stage of microalbumin. The absorption coefficient relationship is used to determine the specific gravity of proteinuria in urine. The minimum linear error rate at 264nm in the best linear region of the albumin absorption band is 1.4%, and the correlation coefficient is 0.9860. The linear error rate of the albumin optical spectrum concentration corresponding to the peak absorption band 285nm is 4.98%, and the correlation coefficient is 0.9502. In addition, the timeliness of albumin was discussed according to the attenuation of the absorbance corresponding to the number of days the albumin was stored. It is hoped that this research will be used as a reference cornerstone for the future development of portable LED biomedical optical systems.
