Potential Symptoms
Levels of the four thyroid-related biomarkers tested can indicate whether your thyroid is under-functioning (hypothyroidism) or over-functioning (hyperthyroidism).
Symptoms Related to Underactive Thyroid
An underactive thyroid gland doesn’t produce enough T3 and T4.
- Fatigue
- Weight gain
- Depression
- Joint and muscle pain
- Sensitivity to cold
- Cold hands and feet
- Difficulty concentrating
- Mental fogginess
- Dry skin and hair
- Frequent, heavy periods
- Constipation
- Slowed heart rate+
- Swelling in the neck from an enlarged thyroid gland
+Slowed heart rate (bradycardia) – commonly less than 60 beats per minute
Symptoms Related to Overactive Thyroid
An overactive thyroid gland produces higher than normal amounts of T3 and/or T4.
As a result, you might experience:
- Unexpected weight loss+
- Increased appetite
- Rapid heartbeat++
- Nervousness, anxiety, and irritability
- Tremors in hands or fingers
- Sweating

++ Rapid heartbeat (tachycardia) — commonly more than 100 beats a minute; or irregular heartbeat (arrhythmia); or pounding of your heart (palpitation
What we measure
Thyroid Hormones • Blood Spot
Free T3, Free T4, TSH
Thyroid hormones regulate how fast or slow the body’s cells work – everything from how fast or slow the heart beats to how quickly or slowly the intestines process food.
Thyroid Antibodies • Blood Spot
TPOAbs
The presence of antibodies in the blood directed against some aspect of the thyroid gland suggests that a thyroid hormone imbalance could be autoimmune related. Thyroid peroxidase antibodies (TPOAb) are among the most clinically relevant of these.
