Scientific Info/Data for Vitamin from Our Equipment and Material Suppliers
Technology Method:
Fluorescence quantitative immunoassay
Detection Bounds:
- Vitamin B12: 20 pmol/L
- Vitamin D: 5.0 ng/L
Accuracy and Precision:
The relative standard deviation from the target value is ≤ 15%. The within-assay CV is ≤ 15%. The between-assay CV is ≤ 15%.
Measuring Ranges:
- Vitamin B12: 20.00~1500.00 pmol/L
- Vitamin D: 5.0~100.0 ng/L
Validation-Active Information:
- EQA: NA
- Inter-laboratory validations
- Periodic according to the validation schedule
- Event-triggered- QC/Calibration/New materials/Batch
Accuracy and Precision:
The accuracy of this Vitamin Exam is based on the relative deviation, which is the average deviation from the actual result value.
The precision relies on the within-assay coefficient of variations and the between-assay coefficient. The within-assay coefficient of variations is the variance of the result value if the same sample is analysed again. The between-assay coefficient is the variance of the result value if the same sample is reprocessed from the beginning again.
In range results:
- B12: 118~701 pmol/L
- D: 30.0~100.0 ng/L
