A calcium blood test is a test that is used to measure the amount of calcium in your blood. Calcium is a very important mineral involved in many body functions, such as maintaining your skeleton, muscular contraction, nerve function, and blood coagulation.
Over 2 million calcium requests are made annually in the UK alone. This blood test is a way of measuring the amount of calcium in the body and gives valuable information concerning your health.
Benefits accrued from routine tests include the early diagnosis of health problems related to calcium imbalance, whose intervention is appropriate and timely.
A calcium blood test is vital for several reasons. It can help indicate conditions like osteoporosis or Paget’s disease, and since the kidneys regulate calcium levels, an imbalance may also suggest kidney dysfunction.
At our City Walk-In Clinics, we offer same-day appointments, full price transparency (no hidden costs), and no phlebotomy fee, all designed to make your testing as smooth and convenient as possible.
We typically recommend booking a calcium blood test at one of our London clinics if you are experiencing symptoms such as muscle spasms, weakness, or fatigue.
It is also advised for those undergoing treatment for conditions affecting calcium metabolism, or for individuals with a family history of bone disorders or kidney disease.
Additionally, people being monitored for other health conditions that could impact calcium levels may benefit from this test to ensure proper calcium regulation.
Calcium levels are usually reported as total calcium and may also include ionised calcium levels.
Normal total calcium levels typically range from 8.5 to 10.2 mg/dL, while ionised calcium levels should be between 4.6 to 5.3 mg/dL.
Use our online booking engine or book your test by giving us a call.
On the online booking engine select the “appointment type” you need.
You will be seen by one of our friendly phlebotomists or trained clinicians.
Follow any specific instructions provided, and inform your healthcare provider about any medications, supplements, or vitamins you are taking, particularly calcium or vitamin D supplements, as these may affect the results. Your doctor might ask you to stop taking them before the test.
The calcium blood test is a simple procedure that involves drawing blood, usually from a vein in your arm. It typically takes only a few minutes. You may experience a slight prick or mild discomfort when the needle is inserted, but this sensation is brief.
Mild bruising or tenderness is common and should resolve within a few days. Your results will typically be available within 1 – 2 days, depending on the lab. If abnormal calcium levels are detected, your doctor may order additional tests to determine the cause, such as assessing vitamin D levels or kidney function.
