Figure Lengend Snippet: Typical MRM chromatogram of VD-DC mass spect gold® serum spiked with 20 ng mL −1 of D3, 25(OH)D3, 1,25(OH)2D3 and 5 ng mL −1 I.S. using the developed UHPLC-ESI-MS/MS method (transitions were m / z 493.4 → 231.3 for D3, m / z 509.4 → 231.3 for 25(OH)D3, m / z 525.4 → 247.3 for 1,25(OH)2D3, and m / z 521.4 → 247.3 for I.S).
