This panel combines TSH with Free T4 (thyroxine), giving you a more complete picture of thyroid function than TSH alone. Free T4 measures the active, unbound thyroid hormone available to your body. Together, these two tests can distinguish between primary thyroid disease and pituitary problems.
Combined first-line and confirmatory thyroid test in one draw. TSH screens for dysfunction; Free T4 distinguishes primary hypothyroidism, hyperthyroidism, and central causes.
Anyone with fatigue, weight changes, hair thinning, mood swings, irregular periods, or a family history of thyroid disease — the standard initial thyroid workup.
