High-cholesterol diagnosis carried out by measuring the cholesterol levels, particle number, and particle size in the blood.
Why Cholesterol Test?
This basic blood cholesterol test is the traditional lipid profile to determine cardiovascular risk is a good start. However, should always combine with advanced testing to get an accurate picture of total health.
The cholesterol numbers are a poor predictor of heart disease. Half of the people hospitalized with heart attacks have normal cholesterol levels; on the other hand, half the people with elevated cholesterol have been healthy.
Raised cholesterol level is a sign of other health conditions. The blood cholesterol tests can further help investigate and treat respective health condition. Thus, instead of using the cholesterol test to predict heart disease; you can use it for diagnosing underlying health conditions such as hypothyroidism, liver problem, inflammation, etc. Even low cholesterol level has linked with cancer. Therefore, cholesterol test is important to assess and maintain your health.
Specifically, for people with familial hypercholesterolemia testing and managing blood cholesterol level is much more important to prevent cardiovascular diseases and to live longer. Thus, cholesterol testing help to lower their risks, so lipid profile test is considering as a preventive health care test for them.
Who should be cholesterol tested and how often?
All adults over 20 years of age should undergo a complete lipid profile test for every five years. If the lipid levels are repeatedly normal, go longer between tests. If the lipid levels are borderline high, then should assess the reason for the rise in cholesterol level and get proper treatment for underlying condition until blood cholesterol level normalizes. During this time, require more frequent testing.
Generally, lipid profile test should carry out for every year for people with diabetes, high blood pressure, heart disease or stroke.
Is it necessary to fast before a cholesterol test?
Before taking blood test for cholesterol needs to fast (not eat or drink anything except water) for 9 to 12 hours. However recent studies clarify that the reading with and without fasting are same so fasting is not necessary. We suggest you to consult your doctor and the lab for proper procedure, before going for a test. Our suggestion is better to take test 9 to 12 hours of fasting by drinking only water.
Cholesterol diagnosis test; Lipoprotein profile provides information on total cholesterol, LDL or supposed bad cholesterol (actually not), HDL or alleged good cholesterol (actually not sure) and triglyceride's levels in the blood.
Influencing factors for cholesterol test
Immediately, after any illness, the cholesterol level is natural to drop temporarily; particularly, after a heart attack, stroke, surgery, or accident. You have to wait for at least six weeks after illness, for your cholesterol level to stabilize.
During pregnancy, it is normal for the cholesterol level to elevate, so it is advisable to wait for at least six weeks after giving birth to have the cholesterol level tested.
Some medications can elevate the cholesterol level, which include beta-blockers, epinephrine, anabolic steroids, oral contraceptives and vitamin D. Thus, stop taking these medications for at least 24 hours before a test.
Common tests for cholesterol diagnosis & management
Lipodology has been in fast pace development; thus, there are various traditional and modern tests are available for cholesterol diagnosis and management. These tests are:
- Lipoprotein profile test – is an early cholesterol test, provides cholesterol levels of HDL, VLDL, LDL and total cholesterol.
- Particle number test – is one of the modern tests to measure the number of LDL/HDL particles in set volume of blood.
- Particle size test – is one of the modern tests to measure the different particle size ranges of the LDL/HDL particles in set volume of blood.
Cholesterol diagnosis is carryout to protect from heart diseases. However, there are numerous direct tests to monitor the heart health. Some tests to assess heart-disease risk are:
- C-Reactive Protein (CRP) - is an inflammation marker test, this is a reliable predictor of heart health than elevated cholesterol levels.
- Fibrinogen - is a platelets' stickiness test. Elevated levels might be a risk towards plague formation.
- Lipoprotein (a) - Lp (a) is a special type of LDL particle bound to apolipoprotein (a). It was learned that a very high percentage of heart attacks occurred to people with raised Lp(a) levels.
- Homocysteine - is a test to determine foliate or B12 deficient, this help diagnoses the inherited disorder called homocystinuria. This condition may increase the risk of heart attack or stroke.
- Interleukin-6 - is an inflammatory cytokine stimulates the liver to produce CRP; it has a strong association with heart disease and asthma.
- Coronary Calcium Scan - helps to view coronary calcification, this is a major risk factor predicting heart disease and future heart attacks.
