What does it detect?
Most organic compounds taken from food are necessary to sustain life. A lack of vitamins means the number of healthy red blood cells decreases.
Why get one?
A person who has a deficiency may experience symptoms like:
- Breathing problems.
- Lack of concentration.
- Irregular heart rhythm.
- Vitamin B12 helps produce your red blood cells, which carry oxygen around your body.
- Vitamin D: measures how much D you have in your blood, essential for healthy bones, teeth and muscles.
How does it work?
Please make your appointment online and visit us on-site to have your blood drawn by our Registered Clinician. Please note that you must present your ID for your appointment.
- Do not take biotin supplements two days before the appointment.
- Do not take B12 supplements two weeks before the appointment.

Please note that we do not draw blood from children under 16 years old.
What is the Scientific Data from Instrument and Reagent Supplier?
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%.
- Vitamin B12: 20.00~1500.00 pmol/L
- Vitamin D: 5.0~100.0 ng/L
- 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 Vitamin Blood tests is based on the relative deviation. The relative deviation 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 test was analysed again. The between assay coefficient is the variance of the result value if the same sample was reprocessed from the beginning again.
In range results:
- Vitamin B12: 118~701 pmol/L
- Vitamin D: 30.0~100.0 ng/L
