Area of Science:

  • Medical diagnostics
  • Biomedical engineering
  • Spectroscopy

Background:

  • Accurate staging of COVID-19 infection is crucial for effective patient management and understanding disease progression.
  • Previous research has explored various biomarkers, but non-invasive and precise methods for longitudinal tracking remain an area of interest.

Purpose of the Study:

  • To analyze a medical dataset to identify the stage of COVID-19 coronavirus onset.
  • To evaluate the efficacy of Fourier-Transform Infrared (FTIR) spectrometry for distinguishing infection stages.
  • To identify specific wavelength ranges as potential medical markers for COVID-19.

Main Methods:

  • Analysis of a medical dataset comprising blood samples from individuals at 1, 3, and 6 months post-COVID-19 infection.
  • Application of FTIR spectrometry experiments to analyze the collected blood samples.
  • Statistical analysis and calculations to determine the effectiveness of the spectroscopic method.

Main Results:

  • FTIR spectrometry demonstrated a highly effective ability to identify different stages of COVID-19 infection.
  • The method achieved perfect accuracy in distinguishing infection states between 1 and 6 months post-infection.
  • Specific wavelength ranges within the FTIR spectra were identified as potential medical markers.

Conclusions:

  • FTIR spectrometry is a powerful tool for non-invasively staging COVID-19 infection.
  • The identified spectral markers offer potential for developing rapid diagnostic tools.
  • This approach provides a quantitative method for monitoring disease progression and recovery.
