Normal Blood Calcium Levels Depend on Age
5 rows · In our bodies, calcium is a mineral that makes up our bones, as well as a salt that dissolves in. Although some labs will report the lower range of blood calcium to be about mg/dl, this is rarely true. Almost everybody, regardless of age should have calcium levels above mg/dl. Almost all adults over 35 have blood calcium levels between and mg/dl. .
Phone: In our bodies, calcium is a mineral that makes up our bones, as well as a salt that dissolves in our blood and regulates bodily function. At UCLA, the normal range for blood calcium level is 8. In order to maintain a normal calcium level, the body uses hormones to regulate blood calcium levels. The normal regulation of calcium in our blood stream is similar to the way a thermostat works.
The body is set to have a normal amount of calcium somewhere between 8. The parathyroid glands are a group of four glands neighboring the thyroid gland that are the main regulators of the blood calcium in your body See Parathyroid Glands-Illustration. Parathyroid glands release parathyroid hormone PTH which increases your blood calcium levels. If the calcium levels are too low, the parathyroid glands will release PTH that will raise blood calcium to the appropriate levels.
If the calcium levels are too high, the parathyroid glands will stop releasing PTH to try to bring the calcium back down to normal. Your blood calcium level would be considered high if it surpasses the upper limit of the normal range, meaning it is greater pevel It is important to re-check your calcium how to search for fossils after czlcium what is normal calcium level elevated blood calcium result to confirm high calcium, otherwise what is up speed when downloading hypercalcemia.
See Hypercalcemia. After confirming a high calcium, your physician would then typically run a parathyroid hormone laboratory panel. The results of this panel will reveal whether or not your high calcium level is due to over-production of PTH from the parathyroid glands see High Calcium.
Uncommonly, high blood calcium levels are due to something other than hyperparathyroidism, leve, as cancers or malignancies not from the parathyroid gland. However, in most patients, high calcium levels are caused by hyperparathyroidism, a condition when the parathyroid glands produce too much parathyroid hormone.
High levels of parathyroid hormone leads to the movement of calcium from the bone and into the blood. Thus, hyperparathyroidism can lead to weaker bones, bone fractures, and other complications such as kidney stones. See Hyperparathyroidism. Learn more about myUCLAhealth. Toggle navigation.

The Total Calcium Blood Test
Jan 24, · Generally speaking, a normal reference range for the blood total calcium test in adults is between and milligrams per deciliter (mg/dL). . Aug 04, · Normal calcium levels in the blood range from to mg/dL in adults and to mg/dL in children. However, levels outside this range are not always a concern; doctors may interpret results differently based on the age of the patient and other health factors. Normal Calcium Levels The reference range may vary slightly between different labs, but a normal calcium blood level is around milligrams (mg) of calcium per deciliter of blood (dL). If your test results fall within this range, your calcium metabolism is on track, and the levels in your blood are being regulated correctly.
We made the Calcium Pro app to make high calcium and parathyroid problems easy to diagnose. Top-3 medical app of , 15, and Read our Parathyroid Blog! Interesting stories about hyperparathyroid patients we see every day.
There are some great stories here! Read the stories of over 2, people who had parathyroid surgery at the Norman Parathyroid Center. What is the Normal Range for Calcium in the Blood?
Blood calcium levels are different depending on your age with children, teenagers and young adults having higher levels of calcium than adults over age 30 or The role of the parathyroid glands is to maintain blood calcium levels in a normal range. This small normal range for blood calcium is different for different ages as shown on the graph below.
The green area on this graph shows how the normal range for blood calcium changes as we go through life. The bottom X axis is our age in years, and the vertical Y axis is the amount of calcium in the blood. Note how the blood calcium increases quite dramatically when we are teenagers and growing bone and getting taller. At age 26 our bones are the strongest and most dense have the most calcium in them , and from that point on, the hormone changes in our bodies causes the amount of calcium in our blood to decrease.
By the time we are 35 we should have most of our calcium levels below Once we are over 40, we should not have calcium levels above Almost all people over 40 have calcium levels "in the 9's".
If you are in Europe and Canada, the high limit of normal calcium is 2. One of the most common mistakes we see while evaluating thousands of patients every year for hyperparathyroidism and high blood calcium, is that doctors are not aware that the lab is not giving a "normal range" according to that patient's age. Instead, the lab will often give a normal range for "all humans" and that normal range will go up to Well technically the lab is correct, this is the range for all humans, but if the patient is 55 years old, then the upper limit of normal on that patient's labs should be The lab is not giving a normal blood calcium range for YOU, it is giving a normal range for all humans of all ages.
We see patients over 40 years old every day who have had blood calcium levels over This is not correct! Blood calcium levels of Enter your age and our calculator will give the upper limit of normal calcium for you.
Your Age. Calcium levels above this should be considered too high for your age. This next graph goes one step further and shows very clearly that patients with hyperparathyroidism have high blood calcium, which is shown in blue. Note that diagnosing a person with hyperparathyroidism who is 18 years old is very different from diagnosing a person who is 65 years old.
A normal, healthy teenager will have blood calcium levels that are above A patient who is 60 years old, however, should have calcium levels "in the 9's". A calcium level of Teenagers with hyperparathyroidism typically have blood calcium levels between For adults over 40 years old, however, frequent or persistent calcium levels above One point here Remember, people of any age above 10 can get a parathyroid tumor, but the peak incidence is between the ages of 50 and See our page on age for more about this.
Other pages of this website have different graphs that show average blood calcium and PTH for our last 20, patients, but here we can easily show that most parathyroid tumors increase the calcium in your blood only modestly which is shown by the purple area. Thus, most adults with hyperparathyroidism have calcium levels "in the 10's".
Remember, adults over 40 or so should have calcium levels "in the 9's". Now you see the biggest challenge we face Every day we see patients with parathyroid tumors who have never had a calcium level that was "out of range" - because the range given was incorrect.
In many areas of life, and many areas in medicine for that matter, a higher number is more significant than a lower number. A cholesterol of is "worse" than a cholesterol of , for instance. Blood calcium levels are the big exception to this rule. This is why we do not recommend "watching" or "monitoring" your slightly high calcium to see if it goes any higher.
First, how high it is doesn't matter! A "slightly" high calcium for a number of years can cause severe health problems discussed in great detail elsewhere. Second, we know what happens when parathyroid disease goes untreated. The calcium level may never get into the "extremely high" range, but over time the risk of complications from the disease including osteoporosis, kidney stones, kidney disease, cardiac arrhythmias, chronic fatigue, memory loss, insomnia, and more rises.
How high the calcium has become is a very poor indicator of the severity of primary hyperparathyroidism. In summary, normal calcium levels vary with age. Your body wants to keep your calcium in a tight range, and the parathyroid glands are responsible for that. For adults over about age 40, the calcium level should generally be in the 9.
High calcium levels almost always indicate parathyroid disease. We know there is a lot of information on the site and it can be hard to take it all in.
