The hormone secreted by the parathyroid gland that raises blood calcium levels is called parathyroid hormone (PTH). PTH acts on bones, kidneys, and intestines to increase calcium levels in the blood by stimulating bone resorption, increasing calcium reabsorption in the kidneys, and promoting calcium absorption in the intestines.
Hormone Calcitonin and Hormone Parathamon
The gland responsible for producing a hormone that increases the level of calcium ions in the blood is the parathyroid gland. The hormone produced is called parathyroid hormone (PTH), which helps regulate calcium levels in the body by increasing calcium absorption from the intestines and releasing it from bones.
Calcitonin is the hormone that responds to high levels of calcium in the blood by promoting calcium deposition in the bones, thus helping to lower blood calcium levels.
Tetany is caused by a disturbance of the blood calcium level. So you can say vitamin D (also considered a hormone) plays a role in it. Also, the parathyroid hormone level has a direct effect on calcium levels.

If you are looking for the one hormone that does this, then the answer is parathyroid hormone (PTH), produced in the parathyroid glands.A more technical description is given below:Three hormones act in the body to increase blood calcium levels to normal. These hormones are 1,25-Dihydroxycholecalciferol, parathyroid hormone (PTH), and calcitonin that originate respectively from the liver and kidneys, parathyroid glands, and thyroid glands. The first, 1,25-Dihydroxycholecalciferol (active vitamin D3), serves to increase calcium absorption from the intestine. The second, PTH, dissolves bone into the blood. The third, calcitonin, prevents the bone-derived calcium from being resorbed ("reabsorbed") into the bone from which it came via PTH. To summarize, these three hormones act in concert to raise calcium levels via external and internal routes.References: Ganong's Review of Medical Physiology, 23eKim E. Barrett, et. al.

Calcitonin is a hormone that can cause a decrease in blood calcium levels by promoting its uptake and storage in bones. It works in opposition to parathyroid hormone, which increases blood calcium levels.
This hormone lowers down the level of calcium ions in your blood. The range of calcium ion is maintained between 9 to 11 mg / 100 ml.
Calcitocin works with parathormone to regulate the calcium level of body. Parathormone rises the calcium level and calcitonin reduces it.
Calcitonin is the hormone released by the extrafollicular cells of the thyroid that causes a decrease in blood calcium levels. It does this by inhibiting the activity of osteoclasts, which are responsible for breaking down bone tissue and releasing calcium into the blood.
Calcitonin lowers blood calcium levels by inhibiting bone breakdown and increasing calcium excretion by the kidneys. Its target tissues are the bones and kidneys. Parathyroid hormone raises blood calcium levels by stimulating bone breakdown, increasing calcium absorption in the intestines, and decreasing calcium excretion in the kidneys. Its targets are bones, intestines, and kidneys.
