Study of Equations for the Non-Invasive Calculation of Hemoglobin Levels

Resumo

In many medical contexts, hemoglobin measurement is a routine procedure. However, the standard test for this parameter is invasive, which may cause discomfort and increase the risk of infection. Consequently, numerous studies have been conducted to develop non-invasive methods for hemoglobin measurement. This study aims to assess the performance of two equations that utilize optical signal data to estimate hemoglobin levels. The average error between the hemoglobin values calculated by these equations and reference values from the literature was analyzed. The equations yielded average errors of 23% and 4%, achieved by incorporating a correction factor into the second equation. These findings suggest that non-invasive hemoglobin estimation is promising, and including correction factors enhances accuracy.
