A. ΔDiHS-NS concentration. Correlation in blood (plasma or serum) ΔDiHS-NS of human subjects between LC-MS/MS and RF-MS/MS is significant (n=187, p < 0.0001).
B. ΔDiHS-0S concentration. Correlation in blood (plasma or serum) ΔDiHS-0S of human subjects between LC-MS/MS and RF-MS/MS is significant (n=187, p < 0.0001).
