An underactive thyroid that produces too few hormones, slowing the metabolism and causing fatigue, weight gain, and low mood. One of the most common hormonal disorders, it is readily treated once detected through blood testing, mainly the TSH value.
Our comprehensive check-up screens for hypothyroidism and hundreds of other conditions.
The ratio of free triiodothyronine (fT3) to free thyroxine (fT4) reflects how efficiently your body converts the storage thyroid hormone (T4) into the active form (T3). A low ratio may indicate impaired conversion, which can occur with stress, illness, selenium deficiency, or certain medications — even when individual thyroid values appear normal.
fT4 / TSH ratioThe ratio of free thyroxine (fT4) to thyroid-stimulating hormone (TSH) provides additional insight into thyroid function by evaluating how the pituitary gland responds to circulating thyroid hormone levels. It can reveal subtle thyroid dysfunction that individual fT4 or TSH values alone may not capture.
Free T4 (fT4)Free T4 is produced by the thyroid gland and converted to active T3 in body tissues.
Free T3 (fT3)Free T3 is the active thyroid hormone that regulates metabolic activity and energy use in cells.
TSHControls thyroid hormone production, which regulates metabolism and energy. Thyroid dysfunction affects many body systems and can cause fatigue, weight changes, temperature sensitivity, and mood disturbances.
TriglyceridesTriglycerides are the main form of fat stored in the body and circulating in blood. They serve as an energy source and are derived from calories not immediately used. Elevated levels increase risk of cardiovascular disease.
LDL cholesterolKnown as "bad cholesterol," it can accumulate in arterial walls, forming plaques that narrow blood vessels and increase risk of heart attack and stroke.
Cholesterol, totalThe overall amount of cholesterol in your bloodstream. High levels can increase risk of heart disease.
