Vitamins D & B12 Test

Vitamins and minerals

The Vitamins D & B12 Test is a targeted nutritional assessment that measures two of the most essential vitamins for energy production, immunity, bone strength, mood balance, nerve function, metabolism, and hormonal regulation.

A DHA-licensed nurse collects your blood sample at your home, office, hotel, or preferred location, using sterile, single-use equipment. The sample is analysed in an accredited laboratory using advanced immunoassay technology for precise measurement.

This test is recommended for individuals experiencing fatigue, low mood, muscle weakness, hair fall, numbness or tingling, poor immunity, bone pain, digestive issues, or dietary restrictions (vegan/vegetarian). After processing, your results are delivered securely via email only.

Parameters: Vitamin D - 25-hydroxy, Vitamin B12
