Parathyroid Profile in Varanasi

The Serum Calcium test measures the levels of calcium in the body. Calcium is the most abundant mineral in the body; most of it is present in the bones and teeth, and the remaining portion (around 1%) is found in the blood. It is usually present in two forms in blood in about equal amounts: "bound calcium," which is attached to proteins in the blood, and "free calcium or ionized calcium," which is not attached to any protein. 

The Serum Calcium test cannot be used to check for lack of calcium in your diet or osteoporosis (loss of calcium from bones) as the body can have normal calcium levels even in dietary calcium deficiency. Moreover, the body can normalize mild calcium deficiency by releasing the calcium stored in bones.

The Phosphorus, Serum test is used to evaluate the level of phosphorus in your blood. Phosphorus is an inherent component of all living cells in the system and most, 85 percent, is located in the tissues of bones and teeth, while the remaining 15 percent is part of the blood and other soft tissues. Your body obtains its daily phosphorus requirements through dietary sources and under normal conditions, once the necessary amounts of phosphorus are absorbed by the cells and tissues, the remaining is eliminated via the urine.

Besides consuming a wholesome diet enriched with sufficient amounts of phosphorus, it is also important to ensure ample intake of calcium and vitamin D, to maintain overall health.

The Vitamin D (25-Hydroxy) test measures the levels of vitamin D in the body. It is an essential nutrient that can be synthesized in the body upon healthy exposure to sunlight or absorbed from dietary sources. It majorly exists in two forms: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D2 is present in plants, such as yeast or mushrooms, and is available as a supplement in fortified foods, and vitamin D3 is found in foods like cheese, green vegetables, mushrooms, egg yolks, and fatty fish.

Both forms of vitamin D (D2 and D3) need to undergo some chemical changes before being available for use in the body. These chemical changes take place in the liver or kidneys. The liver converts vitamin D to 25-hydroxyvitamin D (25-OH vitamin D). The Vitamin D (25-Hydroxy) test measures the level of this 25-OH vitamin D as it is the primary form of vitamin D that circulates in the blood.

A PTH (Intact Parathyroid Hormone) test measures the levels of parathyroid hormone (PTH) in the blood. PTH regulates calcium and phosphorus levels in the body. PTH levels are regulated by a feedback loop with calcium in the blood. Low calcium stimulates PTH release, and high calcium inhibits it. Problems like tumors or damage to the parathyroid glands can disrupt this balance, leading to abnormal PTH levels.

Monitoring of PTH levels is important in managing disorders affecting bone and mineral metabolism, and a PTH (Intact Parathyroid Hormone) test helps assess the function of parathyroid glands and diagnose conditions related to calcium and phosphorus imbalance.
