Calcium - Blood Test - In-Store only


The total calcium blood test is used to measure the total amount of calcium in your blood. Calcium is one of the most important minerals in your body. Most of your body’s calcium is stored in your bones.

  • What can I expect from a calcium blood test?

    The total calcium blood test measures the total amount of calcium in your blood. Your doctor will order this test as part of a routine metabolic panel or if you’re experiencing certain symptoms. Be sure to see your doctor if you’re having symptoms of low or high calcium. In many cases, high or low results have causes that are easily treated. In other cases, you may need a more complex treatment plan to address the underlying condition. Talk to your doctor about your options. They’ll work to identify and treat the disease or condition that’s affecting your calcium levels.

    What could a high level mean?

    Test result values that fall above the reference range are considered high. Having a higher-than-normal blood calcium level is called hypercalcemia.

    Symptoms of high calcium levels can include:

    • tiredness or weakness
    • nausea or vomiting
    • low appetite
    • abdominal pains
    • having to urinate more frequently
    • being constipated
    • excessive thirst
    • bone pain

    Diseases or conditions that can cause hypercalcemia can include:

    • primary hyperparathyroidism (an overactive set of parathyroid glands) or certain types of cancer (together, these account for 80 to 90 percent of hypercalcemic cases)
    • hyperthyroidism (an overactive thyroid gland)
    • kidney or adrenal gland failure
    • sarcoidosis, an inflammatory disease that causes growths called granulomas to develop throughout your body
    • being bedridden or immobilized for a prolonged period of time
    • medications such as lithium and thiazide diuretics
    • taking too much calcium or vitamin D through supplementation

    If you have hypercalcemia, your doctor will aim to identify and treat the condition that’s causing high calcium levels.

    What could a low level mean?

    When your test result values fall below the reference range, they’re considered low. Having a low blood calcium level is called hypocalcemia.

    Typically, hypocalcemia occurs when either too much calcium is lost through your urine or when not enough calcium is moved from your bones into your blood.

    Symptoms of low calcium levels include:

    • cramps in your abdomen or muscles
    • a tingling sensation in your fingers
    • irregular heartbeat

    Some of the potential causes of hypocalcemia include:

    • hypoparathyroidism (an underactive parathyroid gland)
    • kidney failure
    • pancreatitis (inflammation of the pancreas)
    • problems with absorption of calcium
    • certain medications, including corticosteroids, anticonvulsants, and rifampin (an antibiotic)
    • deficiency of calcium or vitamin D in your diet
    • low levels of albumin in the blood, possibly due to malnutrition or liver disease, in which the total calcium level may or may not reflect a truly hypocalcemic state

    Your doctor may treat hypocalcemia through the use of calcium supplements and sometimes vitamin D supplements. If there’s an underlying disease or condition that’s causing your hypocalcemia, they’ll work to identify and treat that as well.
