Vitamin D Test


Testing: Vitamin D2, D3 & Total D (LCMS)

Promotion ends midnight, June 4, 2022.


Vitamin D is an essential hormone necessary for formation, growth and health of bones. Vitamin D deficiency has been linked to increased risk for some common diseases. It’s also required for good immune function and normal calcium uptake. 

Why Test Vitamin D?

Vitamin D deficiency is fairly common, and usually nothing that can’t be corrected with some simple changes to diet or lifestyle. Seriously low Vitamin D, or worse, Vitamin D proficiency, which is when Vitamin D levels are too high, are both more serious and should be investigated with the help of suitably qualified healthcare professionals.

“The Working Group of the Australian and New Zealand Bone and Mineral Society, Endocrine Society of Australia and Osteoporosis Australia have recommended that the Vitamin D level should be greater than 50 nmol/L.” Source: Internet.

Vitamin D Testing – Outcomes and Actions:

  • Calcidiol (25-hydroxyvitamin D)

*What is Liquid Chromatography Mass Spectrometry?

LC-MS is an highly advanced piece of laboratory equipment used in:

  • the detection of residual chemical compounds.
  • confirmatory identification of small organic molecules.
  • confirmation and quantitation (i.e. detection and measurement) of many forms of contaminant, pollutants and adulterants in pharmaceutical and food samples—for example, vanilla.
