Understanding Calcium Blood Levels: Why Doctors Order This Test

When your doctor orders a calcium blood test, they are checking the amount of calcium in your blood. Calcium is a mineral that is very important for your body. It helps your muscles, nerves, and bones work properly. Doctors order this test to make sure your calcium levels are just right.

What Happens if Calcium Levels are Too High or Too Low?

Having too much or too little calcium in your blood can cause problems. If your calcium levels are too high (a condition called hypercalcemia), you might feel thirsty, tired, confusion, or have stomach issues. It can also lead to kidney stones or problems with your bones.

On the other hand, if your calcium levels are too low (a condition called hypocalcemia), you might feel muscle cramps, have tingling in your fingers, or even have seizures. Low calcium can also weaken your bones over time.

Causes of High and Low Calcium Levels

High calcium levels can happen due to a number of different conditions but one of the most common is a condition called hyperparathyroidism (where the parathyroid gland makes too much hormone). Certain cancers, or too much vitamin D can also raise the levels. Diuretics can make the calcium level go up too.

Low calcium levels can be caused by not getting enough vitamin D in your diet, problems with the parathyroid glands, kidney disease, or certain medications.

Things That Can Cause False Readings

Sometimes, factors other than your health can affect the calcium blood test. For example, taking certain medications or having blood drawn from a vein that just had an IV in it can change the results. It’s important to let your doctor know about any medications you are taking or any recent medical procedures you’ve had.

What to Do if Your Levels Are Abnormal

If your calcium blood test shows abnormal levels, the first step is to repeat the test. This helps make sure the result is accurate and not just a one-time thing. If the level is still abnormal your doctor might also want to do other tests to find out why your calcium levels are high or low.

In conclusion, understanding your calcium blood levels is important for your overall health. It helps doctors keep track of how well your body is functioning and can catch problems early. If you have any questions about your calcium levels or why your doctor has ordered this test, don’t hesitate to ask. Your doctor is there to help you stay healthy and feel your best.
