Serum Calcium (Corrected)

Specimen Required

3-5cc Clotted Blood or Serum

Fasting Required

Purpose of the Test

The serum calcium test is typically ordered when a healthcare provider suspects that a patient has a condition that may affect calcium levels, such as hyperparathyroidism or kidney disease. It may also be ordered to monitor treatment for such conditions or to evaluate a patient’s risk for developing osteoporosis.

When this test is required

The serum calcium test is typically ordered by a healthcare provider if they suspect that a patient has a condition that affects calcium levels, such as kidney disease, parathyroid gland disorders, or vitamin D deficiency. It may also be ordered as part of a routine health check-up, especially in individuals who are at risk for osteoporosis.

What the Test Detects

Serum calcium (corrected) is a blood test that measures the amount of calcium present in the blood and is used to determine the corrected calcium level in the body. The test measures both the ionized calcium and protein-bound calcium in the blood.

Preparation for the Test

There are no specific test preparations required for the serum calcium test. However, it is important to inform the healthcare provider of any medications the patient is taking, including over-the-counter drugs and supplements, as they can affect calcium levels in the blood. Additionally, fasting may be required before the test, depending on the healthcare provider’s instructions. It is important to follow all instructions provided by the healthcare provider.

Sample Requirements

The serum calcium test is a blood test, and a small sample of blood is required. During the test, a healthcare professional will insert a needle into a vein in the arm, and a small amount of blood will be drawn into a test tube.

Additional Notes

It is important to note that the reference range for serum calcium levels can vary depending on factors such as age, sex, and underlying medical conditions. The healthcare provider will interpret the results based on the patient’s individual medical history and other laboratory tests. Certain medications and supplements can also affect calcium levels in the blood, so it is important to inform the healthcare provider of any medications or supplements that the patient is taking before the test.
