Casting iron in a sand mold. In metalworking, casting means a process, in which liquid metal is poured into a mold, that contains a hollow cavity of the desired shape, and is then allowed to cool and solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
A normal blood sugar level is between 72 mg/dL and 108 mg/dL (4 to 6 mmol/L) for a healthy person. The concentration of glucose in the blood of a healthy person in the morning on an empty stomach is between 68 mg/dL and 108 mg/dL (3.8 and 6.0 mmol/L).
When your blood sugar dips too low, it is known as hypoglycemia. When your blood sugar rises too high, it is known as hyperglycemia. Both of these can cause symptoms and serious problems within the human body. A normal range for morning blood sugar levels is 70 to 100 milligrams per deciliter (mg/dL). This is known as a fasting level, since the person has not yet eaten. Once you do eat, normal blood sugar will rise to a level not exceeding 140 mg/dL.
