What is a normal PTH level in blood?
Normal values are 10 to 55 picograms per milliliter (pg/mL). Normal value ranges may vary slightly among different laboratories.
How is PTH measured?
PTH is generally measured in serum or preferably in ethylenediaminetetraacetic acid (EDTA) plasma because PTH is more stable in EDTA plasma than serum. It should be noted that PTH value in EDTA plasma tends to be up to 20% lower than that in serum from the same blood sample.
When is PTH measured?
A PTH test may be ordered when a test for calcium is abnormal. It may be ordered when someone has symptoms associated with increased calcium, such as: Fatigue.
What does it mean when PTH is high?
High PTH levels could also indicate a lack of calcium. This could mean you’re not getting enough calcium in your diet. It can also mean that your body isn’t absorbing calcium, or you’re losing calcium through urination. High PTH levels also point to vitamin D disorders.
What is the normal level of PTH in the blood?
The normal level of PTH in the blood stream is between 10-65 picograms per milliliter (pg/mL) in most laboratories. When one or more of the parathyroid glands produce too much PTH, the excess hormone removes calcium from the bones and adds it to the blood. The bone calcium loss eventually causes osteoporosis.
What happens if PTH is too high?
PTH levels become high. Bones weaken. This may cause bone pain and fractures. Calcification of tissues and organs can occur throughout the body. The lungs, heart, blood vessels, joints and skin may be affected.
What does elevated PTH level mean?
Elevated PTH means that you have elevated parathyroid hormone. This is also known as hyperparathyroidism . Now this can be an issue in the parathyroid glands- they are secreting too much hormone.
What does high level of PTH mean?
High PTH means that one has hyperparathyroidism which in Indian scenario is commonly seen with vitamin D deficiency (secondary hyperparathyroidism). Other common cause is adenoma of parathyroid gland (primary hyperparathyroidism). In normal individuals, PTH level is rises whenever there is fall in calcium levels.
