Using logistics regression on laser-induced breakdown spectroscopy (LIBS) spectra of plasma samples collected pre- and post- Covid-19 pandemic from donors known to have developed various levels of antibodies to the SARS-Cov-2 virus, University of Massachusetts physics professor Nourddine Melikechi’s research team has shown that relying on the levels of sodium (Na), potassium (K), and magnesium (Mg) together is more efficient at differentiating the two types of plasma samples than any single blood metal alone. We spoke to Melikechi about this research.
