Panel overview

Tired all the time? This panel checks the most common nutritional causes of fatigue — iron, B12, folate, and vitamin D — with a full iron study to get to the root of the problem.

Included tests and biomarkers

Iron Studies

Sample: Blood Turnaround: 2 days
Iron Ferritin TIBC Transferrin Saturation

Test description

Goes beyond a simple iron level to understand your full iron picture — how much you have in storage, how much is circulating, and whether your body can transport it effectively.

Biomarker descriptions

Iron

Iron is essential for making haemoglobin, the protein that carries oxygen in your red blood cells. This test measures the iron circulating in your blood right now.

Ferritin

Iron storage protein

TIBC

Total iron-binding capacity measures how much transferrin — your body's iron transport protein — is available to carry iron. It helps distinguish between different causes of iron imbalance.

Transferrin Saturation

Transferrin saturation tells us what percentage of your iron transport protein is actually carrying iron. Low saturation points to iron deficiency, while high levels can indicate iron overload.

Vitamin & Energy Screen

Sample: Blood Turnaround: 3 days
Vitamin B12 Folate Vitamin D Ferritin

Test description

Feeling tired all the time? This test checks the vitamins and minerals most commonly linked to fatigue — B12, folate, vitamin D, and iron stores — so you can take targeted action.

Biomarker descriptions

Vitamin B12

Vitamin B12 is vital for nerve function, red blood cell production, and DNA synthesis. Deficiency can develop gradually and cause fatigue, numbness, and cognitive difficulties.

Folate

Folate (vitamin B9) is essential for cell division and DNA repair. It's especially important during pregnancy. Low levels can contribute to anaemia and are easily correctable with diet or supplements.

Vitamin D

25-hydroxy vitamin D

Ferritin

Iron storage protein
