Urine Test
Parathyroid Hormone (PTH) Blood Test
£102.00
Assess your calcium and bone metabolism with a private Parathyroid Hormone (PTH) blood test at Medical Diagnosis Victoria (MDX Victoria) in London.
This test measures the level of parathyroid hormone circulating in your bloodstream. Produced by the parathyroid glands, PTH plays a central role in regulating calcium and phosphate balance throughout the body. Measuring PTH levels is essential for diagnosing parathyroid disorders, investigating the underlying causes of hypercalcaemia or hypocalcaemia, and assessing metabolic bone diseases.
With a 5-day turnaround, this UKAS-accredited test provides the precise diagnostic insights your doctor needs to evaluate endocrine function, identify mineral imbalances, and guide targeted medical management.

Diagnostic Focus
What is the Parathyroid Hormone (PTH) Test?
Parathyroid hormone is secreted by the four tiny parathyroid glands located directly behind the thyroid gland in the neck. PTH serves as the primary regulator of calcium and phosphate homeostasis in the human body. When blood calcium drops, the parathyroid glands release PTH to draw calcium from bone, stimulate renal calcium reabsorption, and trigger active Vitamin D synthesis. Measuring circulating PTH provides essential diagnostic clarity when assessing disorders of calcium balance and metabolic bone health.
Calcium & Phosphate Control
Evaluating intact PTH is crucial for:
- Investigating unexplained hypercalcaemia
- Diagnosing the root cause of hypocalcaemia
- Evaluating disordered phosphate levels
- Assessing active Vitamin D activation
Parathyroid Disorders
This test is highly useful because it:
- Identifies primary hyperparathyroidism (adenomas)
- Evaluates secondary hyperparathyroidism
- Diagnoses postoperative hypoparathyroidism
- Differentiates causes of endocrine hypercalcaemia
Renal & Bone Health
The laboratory provides critical data to:
- Monitor chronic kidney disease (CKD-MBD)
- Investigate recurrent kidney stone formation
- Assess accelerated bone loss and osteopenia
- Support specialists in endocrinology
Clinical Uses
Why is Blood Testing for PTH Important?
Because parathyroid hormone directly dictates how much calcium circulates in your blood and how much is deposited in your bones, both an excess and a deficiency carry significant physiological consequences. Left untreated, chronic parathyroid dysfunction can lead to brittle bones, kidney stones, cardiovascular strain, and severe neuromuscular issues.
Evaluating Physical Symptoms
You should consider this test if you are experiencing symptoms associated with calcium imbalances, such as:
- Symptoms of elevated calcium (Hypercalcaemia): Persistent fatigue, bone and joint aches, kidney stones, frequent urination, abdominal pain, constipation, and low mood.
- Symptoms of low calcium (Hypocalcaemia): Muscle twitches, severe cramps, numbness or tingling around the mouth and fingers, and muscle spasms.
- Unexplained bone fragility, osteopenia, or early-onset osteoporosis.
Ongoing Medical & Diagnostic Use
Doctors frequently recommend serum PTH testing to manage complex diagnoses, including:
- Investigating abnormal total or ionised calcium results discovered during routine blood screening.
- Monitoring patients with chronic kidney disease (CKD) to detect renal osteodystrophy and secondary hyperparathyroidism early.
- Post-surgical surveillance following thyroid or parathyroid surgery to evaluate parathyroid gland preservation and recovery.

Pathology Reports
How To Read Your Laboratory Results
Parathyroid hormone results must always be interpreted in conjunction with your blood calcium levels. A high PTH level paired with high calcium strongly indicates primary hyperparathyroidism (often caused by a benign parathyroid adenoma). A high PTH level paired with normal or low calcium typically points to secondary hyperparathyroidism, often resulting from severe Vitamin D deficiency or kidney disease. Conversely, low PTH combined with low calcium indicates hypoparathyroidism. Your doctor will assess these values alongside your complete metabolic profile.
Results Timeline: Your specialist endocrinology report is typically available within 5 days of your blood draw.
Medical Consultation
Need Help? Private GP Consultations
Endocrine and metabolic bone disorders require skilled medical oversight. If your test demonstrates abnormal PTH or calcium levels, or if you are troubled by persistent bone aches, fatigue, or muscle cramps, we offer private GP consultations on site. Our clinical team can review your report, arrange complementary Vitamin D, calcium, and kidney panels, and coordinate referrals to endocrinologists or nephrologists where indicated.

Frequently Asked Questions
Do I need to fast before the PTH blood test?
No special fasting is strictly required before this blood test. However, because PTH exhibits natural diurnal variation (peaking during sleep and early morning), clinicians often recommend having your blood drawn in the morning. Follow any specific instructions provided by your referring doctor.
Why is PTH almost always evaluated alongside Calcium?
PTH cannot be interpreted clinically in isolation. Because the primary role of PTH is to regulate calcium, knowing whether your blood calcium is high, normal, or low is essential to determine whether the parathyroid glands are responding appropriately or malfunctioning autonomously.
How quickly will I get my results?
Your sample is processed by our accredited specialist laboratory, and your comprehensive results will be securely delivered within 5 days.
Is the phlebotomy fee included in the £102.00 price?
No, the £24.00 phlebotomy service fee is separate and covers the professional process of drawing your blood at our clinic, ensuring transparent pricing and no hidden costs.
What is the difference between the thyroid and parathyroid glands?
Although they sit beside each other in the neck, they have completely different functions. The thyroid gland controls your metabolic rate, body temperature, and energy expenditure. The four parathyroid glands function strictly as calcium and phosphate regulators.

Most Searched Online Questions About Parathyroid Health
What are the primary symptoms of hyperparathyroidism?
Hyperparathyroidism is traditionally remembered by clinicians as “bones, stones, groans, and psychic moans.” It causes bone pain and osteopenia (bones), kidney stones (stones), abdominal discomfort, nausea, and constipation (groans), and persistent fatigue, brain fog, and depression (psychic moans).
How does Vitamin D deficiency cause high PTH?
Vitamin D is necessary for your intestines to absorb calcium from your diet. When Vitamin D is severely deficient, calcium absorption drops, prompting the parathyroid glands to overproduce PTH in an effort to pull calcium from your skeleton into the blood (secondary hyperparathyroidism).
How is primary hyperparathyroidism treated?
Primary hyperparathyroidism is most commonly caused by a single benign growth (adenoma) on one of the parathyroid glands. In symptomatic or high-risk cases, minimally invasive surgery to remove the affected gland (parathyroidectomy) is curative.
