Comprehensive blood test to diagnose parathyroid disorders like hyperparathyroidism or hypoparathyroidism.
This test measures Parathyroid Hormone (PTH) levels in the blood. PTH regulates calcium and phosphate levels, crucial for various bodily functions. Abnormal PTH levels can indicate bone health issues, kidney problems, and calcium imbalances. The test aids in diagnosing hyperparathyroidism (excess PTH) and hypoparathyroidism (insufficient PTH). Monitoring PTH helps manage calcium-related disorders.
Key Details
Who Is This For?
Anyone experiencing unexplained fatigue, weight changes, hair loss, cold sensitivity, or mood disturbances. People with a family history of thyroid disease or autoimmune conditions. Women planning pregnancy, as thyroid function is critical for fetal brain development. Anyone who has had a 'normal' TSH result but still suspects thyroid dysfunction.
What's Included
Preparation Required
No fasting required for a standalone thyroid panel. If you take thyroid medication (levothyroxine/Synthroid), take your dose after the blood draw, not before — taking it beforehand can temporarily spike T4 levels and skew results. Morning testing is recommended for the most consistent TSH readings, as TSH follows a circadian rhythm and peaks overnight.
Biomarkers Tested
4PTH regulates calcium levels in the blood. High levels may indicate parathyroid disorders, while low levels may suggest nutritional deficiencies.
The primary screening test for thyroid function. TSH is produced by the pituitary gland to regulate thyroid hormone production. High TSH indicates an underactive thyroid (hypothyroidism), while low TSH suggests an overactive thyroid (hyperthyroidism).
The unbound, active form of the main thyroid hormone T4. Free T4 directly reflects thyroid gland output and is used alongside TSH to diagnose and monitor thyroid disorders.
The active form of thyroid hormone responsible for regulating metabolism, energy, and body temperature. Free T3 is converted from T4 in tissues and is three to four times more potent than T4.
