Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
9.1 Precision
Precision was evaluated consistent with NCCLS document EP5. Two replicates each of three patient samples and one commercial control sample were tested on two separate occasions per day on at least 20 different days. The experiment was performed using three reagent lots on two different systems. The data presented are a representation of the product performance.
9.2 Linearity
The method was based on CLSI EP6-A ("Evaluation of the Linearity of Quantitative Measurement Procedures: A Statistical approach; Approved Guideline"). Two lots of VITROS 25-OH Vitamin D Total Assay (tVitD) were tested using three VITROS Systems (one VITROS ECi/ECiO Immunodiagnostic System, one VITROS 3600 Immunodiagnostic System, and one VITROS 5600 Integrated System). Two pools of VITROS 25-OH Vitamin D Total Assay samples were prepared with patient samples and were selected near the extremes of the calibration range. The low pool had an estimated concentration of 6.73 ng/mL. The high pool had an estimated concentration of 175 ng/mL. The low and high concentration pools were sequentially mixed to give 7 further pools of intermediate concentrations. All results from both Master Lot 1 and 2 and all three VITROS Systems supported a measuring range of 12.8 to 126 ng/mL. Analysis by weighted linear regression indicated that the assay results across the entire claimed range (12.8 to 126 ng/mL) are best fitted by a third order polynomial regression. In all cases, the third order polynomial regression had non-linear significant terms and/or was the best fit for the assay results. The linear regression fitted results deviate less than 15% from the third order polynomial regression. The assay is therefore linear over the entire range from 12.8 to 126 ng/mL.
9.3 Limit of Detection
The Limit of Detection (LoD) for VITROS 25-OH Vitamin D Total Assay is 8.64 ng/mL (21.6 nmol/L), determined consistent with CSLI document EP17 and with proportions of false positives (α) less than 5% and false negatives (β) less than 5%; based on 700 determinations, with 1 blank and 6 low-level samples. The Limit of Blank (LoB) is 4.34ng/mL (10.9 nmol/L). The Limit of Quantitation (LoO) is 12.8 ng/mL (32.0 nmol/L) as determined by the lowest concentration at which precision design requirements are still met and within the linear range of the assay. At 12.8ng/mL (32.0 nmol/L), the observed imprecision (%CV) is 10% bias at the test concentrations. The VITROS 25-OH Vitamin D Total test was evaluated for interference consistent with CLSI document EP7 A2. Of the compounds tested, none was found to cause a bias of >10% with the test at the concentrations indicated at 25-OH Vitamin D concentrations of 30-80 ng/mL(75-200nmol/L).
Method Comparison
The method was consistent with CSLI document EP9-A2-IR ("Method Comparison and Bias Estimation Using Patient Samples"; Approved Guideline -Second Edition) Interim Review. A minimum of 117 human serum samples were assayed using the VITROS® Immunodiagnostic Products 25-OH Vitamin D Total assay on the VITROS Systems and the IDS-iSYS® 25-Hydroxy Vitamin D assay on the IDS-iSYS System All human serum samples were run in singleton on all systems. The highest sample (Sample ID: R204553) was approximately 95% of the top of the measuring range of the VITROS 25-OH Vitamin D Total Assay (i.e. 120 ng/mL). Seven (7) -spiked and one pooled sample were used for this test. Passing & Bablok Regression was performed for all comparisons. In each case, the VITROS 25-OH Vitamin D Total assay results were plotted as the "y" variable and those from the IDS-iSYS assay as the "x" variable. For the quantitative comparison, only those data within the measuring range of the compared IDS-iSYS and VITROS assays were analyzed. The measuring range for the VITROS 25-OH Vitamin D Total is 12.8 - 126 ng/mL. The IDS-iSYS measuring range is 6-126 ng/mL. Fourteen (14) samples were below the VITROS 25-OH Vitamin D Total assay's measuring range on the 3600 Integrated system and fifteen (15) samples were below the VITROS 25-OH Vitamin D Total assay's measuring range on the 5600 Integrated system and the ECi/ECiQ Immunodiagnostic system. The parameters of the Passing & Bablok Regressions were used to state the equations for the product claim for testing with the VITROS ECi/ECiQ Immunodiagnostic System, the VITROS 3600 Immunodiagnostic System and the VITROS 5600 Integrated System. The comparisons of VITROS to IDS-iSYS are as follows: VITROS 5600 Integrated System 25-OH Vitamin D Total = 0.99 x IDS-iSYS -5.12 ng/mL, n = 102, r = 0.92. The 95%CI for the slope is 0.86 to 1.12 and for the Intercept is -10.2 to -0.53. VITROS 3600 Immunodiagnostic System 25-OH Vitamin D Total = 1.08 x IDSiSYS -7.87 ng/mL, n = 103, r = 0.93. The 95%CI for the slope is 0.96 to 1.22 and for the Intercept is -12.4 to -2.95. VITROS ECi/ECiQ Immunodiagnostic System 25-OH Vitamin D Total = 0.96 x IDS-iSYS -9.07 ng/mL, n = 102, r = 0.94. The 95%CI for the slope is 0.86 to 1.09 and for the Intercept is -14.2 to -4.69.

tested using three VITROS Systems (one VITROS ECi/ECiO Immunodiagnostic System, one VITROS 3600 Immunodiagnostic System, and one VITROS 5600 Integrated System). Two pools of VITROS 25-OH Vitamin D Total Assay samples were prepared with patient samples and were selected near the extremes of the calibration range. The low pool had an estimated concentration of 6.73 ng/mL. The high pool had an estimated concentration of 175 ng/mL. The low and . high concentration pools were sequentially mixed to give 7 further pools of intermediate concentrations.
All results from both Master Lot 1 and 2 and all three VITROS Systems supported a measuring range of 12.8 to 126 ng/mL. Analysis by weighted linear regression indicated that the assay results across the entire claimed range (12.8 to 126 ng/mL) are best fitted by a third order polynomial regression. In all cases, the third order polynomial regression had non-linear significant terms and/or was the best fit for the assay results. The linear regression fitted results deviate less than 15% from the third order polynomial regression. The assay is therefore linear over the entire range from 12.8 to 126 ng/mL.
9.3 Limit of Detection
The Limit of Detection (LoD) for VITROS 25-OH Vitamin D Total Assay is 8.64 ng/mL (21.6 nmol/L), determined consistent with CSLI document EP17 and with proportions of false positives (α) less than 5% and false negatives (β) less than 5%; based on 700 determinations, with 1 blank and 6 low-level samples. The Limit of Blank (LoB) is 4.34ng/mL (10.9 nmol/L). The Limit of Quantitation (LoO) is 12.8 ng/mL (32.0 nmol/L) as determined by the lowest concentration at which precision design requirements are still met and within the linear range of the assay.
At 12.8ng/mL (32.0 nmol/L), the observed imprecision (%CV) is 10% bias at the test concentrations.

તે જે રે Method Comparison
The method was consistent with CSLI document EP9-A2-IR ("Method Comparison and Bias Estimation Using Patient Samples"; Approved Guideline -Second Edition) Interim Review.
A minimum of 117 human serum samples were assayed using the VITROS® Immunodiagnostic Products 25-OH Vitamin D Total assay on the VITROS Systems and the IDS-iSYS® 25-Hydroxy Vitamin D assay on the IDS-iSYS System All human serum samples were run in singleton on all systems. The highest sample (Sample ID: R204553) was approximately 95% of the top of the measuring range of the VITROS 25-OH Vitamin D Total Assay (i.e. 120 ng/mL). Seven (7) -spiked and one pooled sample were used for this test.
Passing & Bablok Regression was performed for all comparisons. In each case, the VITROS 25-OH Vitamin D Total assay results were plotted as the "y"
10
variable and those from the IDS-iSYS assay as the "x" variable. For the quantitative comparison, only those data within the measuring range of the compared IDS-iSYS and VITROS assays were analyzed. The measuring range for the VITROS 25-OH Vitamin D Total is 12.8 - 126 ng/mL. The IDS-iSYS measuring range is 6-126 ng/mL. Fourteen (14) samples were below the VITROS 25-OH Vitamin D Total assay's measuring range on the 3600 Integrated system and fifteen (15) samples were below the VITROS 25-OH Vitamin D Total assay's measuring range on the 5600 Integrated system and the ECi/ECiQ Immunodiagnostic system. The parameters of the Passing & Bablok Regressions were used to state the equations for the product claim for testing with the VITROS ECi/ECiQ Immunodiagnostic System, the VITROS 3600 Immunodiagnostic System and the VITROS 5600 Integrated System.
The comparisons of VITROS to IDS-iSYS are as follows:
VITROS 5600 Integrated System 25-OH Vitamin D Total = 0.99 x IDS-iSYS -5.12 ng/mL, n = 102, r = 0.92. The 95%CI for the slope is 0.86 to 1.12 and for the Intercept is -10.2 to -0.53.
VITROS 3600 Immunodiagnostic System 25-OH Vitamin D Total = 1.08 x IDSiSYS -7.87 ng/mL, n = 103, r = 0.93. The 95%CI for the slope is 0.96 to 1.22 and for the Intercept is -12.4 to -2.95.
VITROS ECi/ECiQ Immunodiagnostic System 25-OH Vitamin D Total = 0.96 x IDS-iSYS -9.07 ng/mL, n = 102, r = 0.94. The 95%CI for the slope is 0.86 to 1.09 and for the Intercept is -14.2 to -4.69.
