PTH (Parathyroid Hormone)

Parathyroid hormone (PTH) helps regulate calcium and phosphorus, which are essential for bone health. For women, PTH balance may be particularly relevant during hormonal transitions such as menopause.

What It Measures

This test measures the level of parathyroid hormone in your blood, reported in pmol/l. PTH helps regulate calcium balance by signaling bones, kidneys, and intestines to adjust calcium and phosphorus absorption and release.

Why It Matters

Women may experience changes in PTH levels during hormonal shifts, potentially affecting bone density and calcium balance. Understanding your PTH levels could help you and your healthcare provider make informed decisions about bone health.

When to Test

Testing may be considered when experiencing unexplained bone pain, frequent fractures, or abnormal calcium levels. Some healthcare providers may also recommend testing if kidney stones occur repeatedly or if vitamin D deficiency is suspected.

Symptoms

Low Levels

Some people with low PTH levels may experience muscle cramps, tingling in the fingers or around the mouth, fatigue, or dry skin. Low PTH could potentially lead to elevated phosphorus and reduced calcium levels over time.

High Levels

Some people with elevated PTH levels may experience bone pain, fatigue, excessive thirst, frequent urination, or kidney stones. High PTH could potentially be associated with weakened bones and elevated blood calcium levels.

Lifestyle Tips

Maintaining adequate vitamin D and calcium intake through diet or supplementation may support healthy PTH levels. Regular weight-bearing exercise could benefit bone health. Consult your healthcare provider before making significant dietary changes.

Frequently Asked Questions

What is a normal PTH level?
Normal PTH levels generally fall between 1.6 and 6.9 pmol/l, though reference ranges may vary between laboratories. Your healthcare provider can help determine what is normal for your individual situation.
Can vitamin D affect PTH levels?
Vitamin D deficiency may cause PTH levels to rise as the body attempts to maintain calcium balance. Ensuring adequate vitamin D intake could help support healthy PTH regulation. Discuss supplementation with your healthcare provider.
Should I fast before a PTH test?
Fasting is generally not required for a PTH test, though your healthcare provider may give specific instructions. PTH levels can fluctuate throughout the day, so morning testing is sometimes recommended for consistency.
