THz absorption spectra of human blood and water. (a) One-minute-averaged THz absorption spectra of human blood thrombus taken from 29 subjects. The spectra were taken at the first minute right after the blood samples had turned into thrombus. (b) THz absorption spectra of pure water (red line) and heparin-added water (black line). Data was summarized from 10 measurements. (c) One-minute-averaged THz absorption spectra of early coagulated human blood taken from 29 subjects. The spectra were taken at the first minute of the measurement, which started around 3 minute after the blood extraction. (d) One-minute averaged 270 GHz absorption constants measured right after the thrombus formation versus RBC count. No correlation was observed (n = 29, p-value = 0.736).
