Info Total Cholesterol Blood Test

When talking about a cholesterol blood test, it means measuring all the cholesterol in your blood.
Cholesterol is kind of a soft substance, like wax, that is in most parts of your body. Every human being needs some cholesterol to have the body function in the right manner. On the other hand when there's more cholesterol than necessary it might obstruct your blood vessels and causing heart disease.
There are two types of cholesterol, indicated as good and bad. For both types require blood tests.

Carrying out the check.
In adults a bit of blood is drawn from a vein, often from the inside of the elbow or the back of the hand. Done by a health care provider who gently inserts a needle into the vein, collecting the blood into a tube attached to the needle. In children the skin is punctured to have it bleed and then collecting the blood.

Reason for the cholesterol blood test.
A risk profile may be done to screen people for high blood cholesterol and or to follow people who have had high cholesterol levels and are being treated.
This blood test is done to determine your risk for coronary artery disease, what is a stage of arteriosclerosis involving fatty deposits inside the arterial walls, thus narrowing the arteries.

Test results.
Total cholesterol test is an important measure of both bad and good cholesterol. Other tests are done to measure specific amounts of good (HDL) and bad (LDL) cholesterol. A cholesterol breakdown including LDL and HDL is preferred under certain circumstances.
In general, a total cholesterol value over 200 mg/dL may mean you have a greater risk for heart disease. However, LDL levels are a better predictor of heart disease, and they determine how your high cholesterol should be treated.

Risks when collecting the blood.
The Vein and artery blood vessels vary in size from one person to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks, although rare, may include excessive bleeding, fainting or feeling light-headed, blood accumulating under the skin and infection (a slight risk any time the skin is broken)

Any acute illness can raise or lower your total cholesterol number. If you have had an acute illness in the three months before having this test, you should have this cholesterol check repeated in two or three months. Even a flare-up of arthritis can affect your cholesterol level.
Other conditions associated with high cholesterol include pregnancy and removal of the ovaries.
