Key testing data of the BloodoTM Vitamin D Test
1. Calibration and linearity
Vitamin D3 and D2 is measured according to a calibration curvereceived against the added Vitamin D3 and D2 standards in real human blood (Figure 1 and Figure 2). A typical calibration curve is conducted using Vitamin D3and D2 concentration range of 6.2 - 250 nmol/l (accounting for dilution), enabling the determination of Vitamin D3 and D2 in DBS samples within this range. Acceptance criteria for error margin is < 60 %. Error margin of the BloodoTM Vitamin D Test for Vitamin D3 is 25 % and for Vitamin D2 – 33 %.
2. BloodoTM Vitamin D test limit of detection and limit of quantification
Limit of detection (LOD) is the lowest amount of analyte which can be detected, but not necessarily quantitated. The limit of quantification (LOQ) is the lowest concentration of an analyte in a sample that can be quantitatively determined with suitable precision and accuracy. LOD and LOQ for the vitamin D3 and D2 were determined from the linearity experiment results. The limit of detection and limit of quantification of the BloodoTM Vitamin D Test for vitamin D3 is 14.2 nmol/l and 23.6 nmol/l, respectively, for DBS samples (whole human blood). The limit of detection and limit of quantification of the BloodoTM Vitamin D Test for vitamin D2 is 16 nmol/l and 26.6 nmol/l, respectively, for DBS samples (whole human blood).
3. Specificity
Specificity is the ability of the assay to unequivocally assess the analyte in the presence of components that may be expected to be present. The characteristics of an LC-MS method impart remarkably high specificity for Vitamin D determination. High-performance liquid chromatography offers fast end effective initial separation of Vitamin D metabolites from the potentially interfering matrix components, reducing the complexity of analyte presentation to the mass spectrometer. Subsequently, mass spectrometry provides discriminatory power by filtering, detecting and quantifying molecules based on their parent ion distinctive mass-to-charge ratios (m/z). Moreover, tandem mass spectrometry (MS/MS), employing techniques like multiple reaction monitoring (MRM), enables fragmentation of the parent ion of Vitamin D metabolites and monitoring of highly specific product ions at different collision energies, further enhancing the method's specificity and minimizing the risk of misidentification. An additional check of product ion abundance ratio is performed to further decrease a risk of misidentification, providing a yet another criterion to ensure unparallel specificity and discrimination of matrix effects.
