Using an Analog Discovery 2 as the basis for the development of an electrical impedance spectroscopy (EIS) kit and the adaptation of the Accu-Chek®test strips as a working electrode to perform readings on samples of human blood tissue, it is possible to obtain the corresponding Nyquist spectra for the mentioned tissue. These results indicate a possible correspondence in the electrical impedance signal observed in people with a hemoglobin amount of 14.8 g/dL, 14.7 g/dL, 14.6 g/dL and 13.7 g/dL. It was also possible to simulate with the data obtained the probable graph of a person with 12.7 g/dL of hemoglobin in blood, which corresponds to a patient with anemia. This article analyzes the viability of developing a new less invasive diagnostic method for anemia disease, which is taking place in the Biophysics Laboratory of the Faculty of Physical Sciences - UNMSM.

This research shows the bioelectrical characterization and impedance reading of nasopharyngeal samples taken during the infection stage of a patient with viral rhinopharyngitis compared to the healthy stage of the same patient. 11 nasopharyngeal samples were taken during the initial phase of infection and 10 nasopharyngeal samples 14 days after not presenting any symptoms. The analysis was carried out in a frequency range of 10 kHz - 1 MHz using the MIVA (Module of Variable Impedance for Analysis) bioelectrical impedance equipment. The results obtained indicated a significant difference in the impedance of the samples during the different stages, which allowed establishing a range in the axes (Z' and Z'') of the Nyquist diagram when a nasopharyngeal sample comes from a case of viral rhinopharyngitis and when the sample comes from a healthy patient. In addition, it will be modified to sch...
