Nutritional Health Basic

A nutritional deficiency screen covering liver and kidney function, iron studies, active B12, folate, and vitamin D. Targets the most common nutritional deficiencies that affect energy levels, immune function, and cognitive health. Iron deficiency and low vitamin D are particularly prevalent in the Australian population despite the climate.

Nutritional deficiencies are surprisingly common in Australia despite access to diverse food sources. This panel targets the most clinically significant deficiencies that affect energy, immune function, and cognitive performance: iron status, B12, folate, and vitamin D, alongside liver and kidney function testing to assess how well the body is processing and utilising nutrients. The iron studies component is more comprehensive than a simple ferritin test. By measuring ferritin, serum iron, transferrin, and total iron-binding capacity (TIBC), it distinguishes between true iron deficiency, iron deficiency masked by inflammation (where ferritin may appear normal), and iron overload conditions like hereditary haemochromatosis — which affects roughly 1 in 200 Australians of Northern European descent. Active B12 (holotranscobalamin) is a more accurate marker of B12 status than total B12, as it measures only the biologically available form. B12 deficiency can cause neurological symptoms including tingling, memory issues, and balance problems well before anaemia develops. Folate works alongside B12 in DNA synthesis and red blood cell formation, and deficiency is associated with elevated homocysteine — an independent cardiovascular risk factor. Vitamin D deficiency affects an estimated 23% of Australian adults, with higher rates during winter and in southern states including Western Australia's southern regions. Beyond bone health, vitamin D is associated with immune regulation, muscle function, and mood. This panel is particularly relevant for vegetarians, vegans, older adults, and anyone experiencing persistent fatigue without a clear cause.
