Thyroid Function Test in Kepong — TSH, FT4, FT3, No Fasting Required

The thyroid gland is small — about the size of a butterfly sitting at the base of your neck — but its influence is enormous. Thyroid hormones regulate metabolic rate, body temperature, heart rate, digestive function, muscle control, brain development, and bone maintenance. When the thyroid is underactive (hypothyroidism), everything slows down: fatigue becomes profound, weight creeps up despite no dietary changes, skin becomes dry, hair thins and falls, bowels slow, and mood flattens. When it's overactive (hyperthyroidism), the reverse happens: racing heart, anxiety, unexplained weight loss, heat intolerance, tremor, and sleep disruption.

Thyroid dysfunction is significantly more common in women than men and becomes more prevalent with age — but it affects all demographics. Many patients with hypothyroidism have been managing symptoms for years before connecting them to thyroid function. A single blood test measuring TSH (thyroid stimulating hormone) is the primary screen — and if that's abnormal, Free T4 and Free T3 are added to fully characterise the dysfunction. No fasting required. Walk in at any time — our in-house doctor reviews results with you immediately.
