Why take this test?

Each system here answers a different part of the question.

Nutrients & ironNutrients & iron · 5 tests

What you have absorbed, and what you have stored.

Iron is a system rather than a number: stores, transport and saturation each read differently, and inflammation shifts them. B12 and folate follow the same logic.

Ferritin · Serum iron · Transferrin · Transferrin saturation · Vitamin B12
ThyroidThyroid · 3 tests

The gland that sets your metabolic tempo.

Thyroid testing separates the signal from the pituitary (TSH) from the hormones themselves (T4, T3) and from antibodies. Read together they describe a pattern; read alone, TSH can mislead.

TSH · Free T3 · Free T4
HormonesHormones · 3 tests

The messengers behind cycle, drive and stress response.

Hormones move with the clock, the cycle and with each other. Free and bound fractions, the binding proteins and the pituitary signals above them are read as one timed set.

DHEA-S · Morning cortisol · ACTH
