What is the normal of pth?
Normal PTH Range:
In general, the normal range for parathyroid hormone (PTH) levels can vary slightly depending on the laboratory performing the test and the methods used. However, the typical reference range for PTH is:
- For adults: 10-65 picograms per milliliter (pg/mL) or 1.6-8.8 picomoles per liter (pmol/L)
- For children: 15-65 pg/mL or 2.5-8.8 pmol/L
It's important to note that the normal range may differ based on factors such as age, sex, and specific laboratory protocols. Therefore, it's crucial to refer to the specific reference range provided by the testing laboratory when interpreting PTH results.
A PTH level that falls outside the normal range may indicate an underlying health condition, such as:
- Primary hyperparathyroidism: A condition in which the parathyroid glands produce too much PTH, often caused by an enlarged or overactive parathyroid gland.
- Secondary hyperparathyroidism: A condition in which the parathyroid glands produce too much PTH in response to another underlying condition, such as chronic kidney disease or vitamin D deficiency.
- Tertiary hyperparathyroidism: A condition in which the parathyroid glands become autonomous and continue to produce excessive PTH, even after the underlying cause of secondary hyperparathyroidism has been corrected.
- Hypoparathyroidism: A condition in which the parathyroid glands produce too little PTH, leading to low blood calcium levels.
If your PTH level is abnormal, your doctor will recommend further tests and evaluations to determine the cause and appropriate treatment.
