Calcium / Corrected Calcium
Together with your calcium blood test result, you’ll also receive other relevant readings including glucose, cholesterol and uric acid to help put your result into the proper context.
Essential for healthy bone and muscle function, calcium is the most common mineral in the body. As well as building teeth and bones, calcium helps nerves to function, muscle contraction, enables your blood to clot and helps your heart beat.
Most of the calcium in your body is stored in your bones and teeth. The rest is in your blood. This test will check the levels of calcium found in your blood, giving a corrected calcium level taking into account the amount bound by albumin in your body. Abnormally high levels of calcium in your blood (hypercalcaemia) can cause kidney stones, weaken your bones and impair your heart and brain function. Hypercalcaemia is often a result of an overactive thyroid, but can also indicate certain types of cancer or tuberculosis. Low levels, or hypocalcaemia, can be due to an underactive thyroid. Low calcium levels can also be caused by kidney disease, low protein or vitamin D, or high phosphate.
All our tests have been specially designed to be convenient and non-invasive. Once you’ve booked your appointment, full preparation instructions will be provided in your confirmation email or letter. You can continue to eat and drink normally before your appointment, and you’ll also remain fully clothed throughout.
