What is a Calcium Blood Test?

A calcium test can determine whether your blood contains too much or too little of this essential element. It’s frequently done as part of a routine check-up. Calcium is the primary mineral component of bones. 99% of the body’s calcium is in the bones and teeth, primarily a vast reservoir for maintaining serum calcium levels.

Why get a Calcium Blood Test?

Your body needs calcium to keep its bones and teeth healthy. It is also essential for maintaining proper nerves, heart, and muscles. A calcium test can determine how effectively your body responds to specific therapies for various diseases. It can also be used to track the side effects of medications you’re taking.


If calcium deficiency is very severe or acute there can be muscle spasms or cramping, tingling, or burning sensation around the mouth and fingers, facial spasms and tics, seizures, and tremors. The loss of calcium from bone is called osteopenia when it is mild and osteoporosis when it is severe.

A fact is that 99% of the calcium from your body is found in your bones, inside the cells and in your blood. Calcium is a must for your teeth and for the formation of your bones.

Calcium is a very underestimated mineral which plays a great role in a lot of processes in your body. Especially in bone and teeth health, but also in muscle contraction, maintaining blood pressure and blood clotting at good levels.

Even if we imagine them as inert tissues, in reality, bone cells are well vascularized and continuously exchange nutrients and waste with the outside. Given that osteoporosis is a condition which causes bone fragility and it is caused by calcium deficiency, most people who risk having it are the elderly, women in menopause, or people who suffer from eating disorders.

Firstly, we must ensure that the intake of calcium through dairy products that we have in our body is neither too low or too high. We can take the right amount of calcium from seafood, vegetables, tofu, squid, octopus, anchovies, and dried fruits.

Then, there are some precautions that we should take to avoid losing what we take.

1- Watch out for phosphorus

Phosphorus is important for our body, but its excess hinders the absorption of calcium at the intestinal level. Not only that, when it is in the blood in the form of phosphoric acid, it lowers the pH, and the body uses calcium to buffer its acidity, removing it from the bones if it is lacking. Finally, phosphorus stimulates diuresis, which, therefore, leads to the excretion of more calcium in the urine.

2- Be careful with salt

Even an excess of sodium is an enemy of bones: the molecule, in fact, competes with that of calcium in reabsorption at the renal level. It means that when the blood passes through the detailed filtering system of the kidneys, it increases the probability that the calcium will not be returned to circulation and will, therefore, be expelled.

3- Don’t overdo it with animal proteins

Excess proteins produce phosphate and sulfate ions when digested; these acidify the blood and activate buffer systems, as in point 1.

4- Go easy on coffee

Each cup of coffee causes us to expel around 6mg of calcium. It’s not much if we consider that our needs range from 800 to 1500 mg, but in an already deficient diet, it can make a difference.

5- Exercise

Exercising is fantastic for your bones. It can increase calcium deposition and strengthen the muscles.

You may not know this, but osteoporosis is not reversible, so it is essential to prevent it while you still can. If you fear you are at risk, contact your doctor: with simple blood tests, he will be able to evaluate your blood calcium level and, if necessary, opt for further tests and prescribe an adequate treatment.

Vitamin D is crucial for the absorption of calcium: in this period in which those who don’t have a garden can hardly expose themselves to the sun, its intake through food is even more important. You can find it in fish, liver and egg yolk.
