Vitamin Laboratory

The PathWest Vitamins Laboratory has over 30 years of experience in the field of vitamin testing helping private companies and government agencies quantitate correct vitamin content in food products.  Methods are chosen for their sensitivity, specificity, fast turn around time and cost effectiveness. The laboratory is involved in new developments and is involved in the Thiamin and Folate fortification program.

We can analyse any type of food for Cobalamin (Vitamin B12), Folate and Thiamin (Vitamin B1).

Please inform the laboratory before sending samples (remember there is a two hour time difference between the Eastern States and Western Australia, three hours when daylight saving is in place).
