This is a natural fat-looking, waxy substance found in the body, and it plays an important role in the proper functioning of the body.
Cholesterol is used by the body to produce several hormones including vitamin D and bile acids which help in the digestion of fat. Do you know that for your body to function normally, it needs only a small amount of cholesterol? Any surplus amount might be packed up in artery walls throughout your body. This is not healthy and can cause:
The cholesterol and triglyceride levels in the blood can be measured using Fasting blood tests. This test is also known as lipoprotein profile or lipoprotein analysis. It is done to measure:
High blood cholesterol levels, smoking, obesity, high blood pressure, amongst others are some of the risk factors that can be managed.
Before taking a cholesterol test, you will have to fast. The essence of fasting is to get a good interpretation of your blood lipid levels. This fasting involves not eating or drinking anything besides water for 14 hours before your blood sample is taken. Alcohol should be avoided 48 hours to the test.
Sadly, this is a no-no. You should not drink coffee or any other liquid before your blood is drawn.
No! A blood sample has to be taken to perform a cholesterol test. Your nurse or doctor will tie a tourniquet around your arm right above your elbow to hold in enough blood. He/she will then insert a needle into a vein in your arm, close to the inside of your elbow. With the needle, a small amount of blood is withdrawn and collected into a vial.
The needle is removed from the vein when the blood is collected, and the tourniquet loosened from your arm. In order to stop blood from leaking out of the punctured area, a small cotton ball is pressed over the area and held in place with a band-aid.
In just a few minutes, your blood can be drawn for the test.
Well, a very small pain comes with blood tests. Besides, some persons get anxious over having their blood drawn, and this alone might cause more pain than the entire process.

Yes, you can resume your normal diet after taking the test. Your doctor or healthcare provider may advise you on resuming any medication that was put on hold before the blood test was done.
Understanding the results of a cholesterol and triglyceride test depends on guidelines from several medical organisations. See the results and interpretation below:
Total cholesterol
Less than 200 mg/dL: desirable
200 - 239 mg/dL: borderline high risk
240 and above: high risk
High-density lipoprotein (HDL)
Lower than 40 mg/dL (in men), lower than 50 mg/dL (in women): increased risk of heart disease
Greater than 60 mg/dL: some protection against heart disease
Low-density lipoprotein (LDL)
Less than 100 mg/dL: optimal
100 -129 mg/dL: near optimal/above optimal
130 - 159 mg/dL: borderline high
160 - 189 mg/dL: high
190 mg/dL and above: very high
Triglycerides
Less than 150 mg/dL: normal
150 - 199 mg/dL: borderline to high
200 - 499 mg/dL: high
Above 500 mg/dL: very high
Are there risks associated with cholesterol test?
Yes, but it is very minimal. Bruising may occur at the puncture site, usually when there is damage to the vein.
Persons on blood thinners listed below may have to apply extra pressure where the blood was drawn to inhibit the bleeding:
Having an infection is rare. If it does occur, it may be characterised with swelling, redness, and pain.
After or during the blood test, some persons might feel dizzy. This is as a result of the vasovagal reaction, where the heart rate is lowered and blood vessels become larger (caused by vagus nerve stimulation). The feeling of Lightheadedness doesn't last and is normally treated by lying down to rest for a while. Vasovagal reaction or near fainting is common with a blood test, but it's a normal and harmless occurrence.
