Total blood cholesterol

This test measures the amount of cholesterol in the blood, which is a type of fat that the body needs in small quantities to build cells and produce hormones. But if the level is high, it can cause narrowing or blockage of the arteries over time, which increases the risk of heart diseases and strokes. The doctor usually requests the test: as a routine check, or if you have weight gain, high blood pressure, or a family history of heart diseases. Mashallah: It is preferable to do the test while fasting for 9–12 hours to get an accurate result, and if it is high, improving diet and exercising helps a lot in lowering it.
