What are the Instructions for use?

Please take your Vitamin Blood Test Kit sample in the morning, at least one hour before any medication.

Moreover, when you collect your sample, try the following tips:

  • Drink plenty of water. Being well-hydrated will make it easier to collect your sample.
  • Shower before you take your test or run your hands under warm water for a few minutes, as heat improves blood flow.
  • Do light exercise (move around, walk, etc.) to get the blood flowing.
  • Ensure your arm is below your heart level – let gravity do some of the work.
  • Nails that are too long can make it difficult to collect a sample.
  • Do not shake the sample vigorously, but gently invert the tube 10 times. (Gently swirl the tube after each drop of blood.)
  • Do not squeeze the finger (milk).
  • Re-warm your hands during collection where needed.

What is the Scientific Data from Instrument and Reagent Supplier?

Technology Method:

Fluorescence quantitative immunoassay

Limit of Detection:

  • 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: Yes
  • Inter-laboratory validations
    • Periodic according to the validation schedule
    • Event-triggered- Qc/Calibration/New materials/Batch

Accuracy and Precision:

The accuracy of these methods 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:

  • Vitamin B12: 118~701 pmol/L
  • Vitamin D: 30.0~100.0 ng/L
