What does a lipid panel test your blood for?
The lipid panel measures:Total cholesterol levelTriglyceride LevelHDL cholesterol "good"LDL cholesterol "bad"Very-low-density lipoprotein (VLDL) cholesterol level.The ratio of total cholesterol to HDL.The ratio of LDL to HDL.Lipid disorders, such as high cholesterol, may lead to life-threatening illnesses, such as coronary artery disease (CAD), heart attack, or stroke.
VLDL test?
DefinitionVLDL stands for very low density lipoprotein. Lipoproteins are substances made of cholesterol, triglycerides, and proteins. They move cholesterol, triglycerides, and other lipids to different parts of the body.There are three major types of lipoproteins. VLDL contains the highest amount of triglycerides. VLDL is considered a type of bad cholesterol, because it helps cholesterol build up on the walls of arteries.This article discusses the laboratory test to measure the amount of VLDL in your blood.See also:HDL testLDL testTotal cholesterol testHigh blood cholesterol and triglyceridesAlternative NamesVery low density lipoprotein testHow the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedYour doctor may order this test to determine your risk of heart disease. Increased levels of VLDL are linked to atherosclerosis, which can lead to coronary heart disease.This test may be included in a coronary risk profile.Normal ValuesNormal VLDL cholesterol level is between 5 and 40 mg/dL.Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanHigh levels may be associated with a higher risk for heart disease and stroke.What the risks areThere is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)Special considerationsThere is no simple, direct way of measuring VLDL. Most labs estimate your VLDL based on your triglyceride level. It is approximately one fifth of your triglycerides level, although this is less accurate if your triglyceride level is above 400 mg/dL.ReferencesExpert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults.

What is Lipid profile test?
Lipid profile is a test using electrophoresis to differentiate between the different types of lipids. A standard test will separate the lipid component of the plasma into TriGlycerides, High Density Lipoprotein cholesterol(HDL), Very Low Density Lipoprotein cholesterol (VLDL) and Total Cholesterol (TC). From the previously mentioned lipids, one would calculate the Low Density Lipoprotein cholesterol as well as the atherogenic indexes be it TC/LDL or LDL/HDL. Measuring the LDL directly is possible but is not standard. Other tests like sub-typing of the LDL or the HDL, as well as Lp(a) are not routein in most laboratories albeit they are frequently performed in research centers.
What are the chemical reaction in the human body?
Since we have about 200 trillion cells and each one performs millions of chemical reactions, the total number of chemical reactions in the human body is too huge to predict with any certainty.UpdateI'm a chiropractic student and watched a video earlier today that indicated the human body undergoes about 400 billion chemical reactions per second every second of your life.Another Possible AnswerThe estimate of cells in the human body ranges from 100-200 trillion. So if every cell did at least one chemical reaction per second, than the number of reactions must truly be higher than 400 billion. Cells perform thousands, if not millions of chemical reactions in every cell every second. I agree with the first answer that the complexity and the total number is too huge to predict or even imagine.If we have 100-200 trillion cells in our bodies, than we have a thousand more times cells in our bodies as the number of stars in the Milky Way galaxy. If we take one step forward and ask how many atoms do we have in our bodies, that number is also about a thousand more galaxies that we know to exist in the universe.Perhaps it is poetic to say that we are truly made of stardust, and each one of us is the product of several second generation stars that threw up enough dust into space to ultimately congeal into our solar system, with our sun as the center, and this wet rocky planet we all call home, Earth, the third rock from the sun.Another UpdateQuite unlikely that *every* cell in our body performs a chemical reaction every second. Consider for instance, that while 60% of our total volume of blood is found in the veins, only 5% is found in the capillaries where nutrient and waste products are exchanged. Considering keratinized epithelial cells, most apical layers are going to be dead so they aren't going to be reacting much and that's a pretty big part of the largest organ in our body, the skin. Assuming a person has decent amounts of calcium then osteoblast and osteclast should be in a reasonable state of homeostasis. Some cardiac tissue does have fast calcium channels but those are only open for a few 10,000ths of a second over the course of a cardiac cycle which is about 0.83 seconds on average (Guyton's). You'll find a vast number of muscles along the spinal column but the greatest numbers of muscles for proprioception are found along the vertebral columns and as such their main function is to provide an awareness of our spatial orientation.The crux of this info comes from biochemistry, physiology and neuroanatomy and all three of my teachers for those classes come from some pretty well respected med schools (Wash U & SLU) - I'm checking the "bible" of physiology - i.e., Guytons Textbook of Medical Physiology and that book does cite 100 trillion for the total number of cells in the entire body. About 25 trillion of those are red blood cells. Of course, rbc's lack mitochondrians so metabolic pathways such as the TCA cycle would be excluded from their repertoire of activity.Even things like a triacylglyceride (TAG) say a VLDL will have a CII polypeptide that's looking for a receptor (which it should find in an adipocyte) but after that's it's an IDL with a B100 polypeptide and that's only going to find a receptor at the liver and it does take times for various lipoproteins to circulate throughout the system.
Cholesterol and triglyceride test?
DefinitionA coronary risk profile is a group of blood tests used to measure your cholesterol and triglyceride levels. The profile can help determine your risk for heart disease.Cholesterol is a soft, wax-like substance found in all parts of the body. Your body needs a little bit of cholesterol to work properly. But too much cholesterol can clog your arteries and lead to heart disease, stroke, and other problems.Some types of cholesterol are considered "good" and some are considered "bad." Different blood tests are needed to measure each type of cholesterol.Alternative NamesLipoprotein/cholesterol analysis; Lipid profile; Lipid panel; Hyperlipidemia - testing; Coronary risk profileHow the test is performedA blood sample is needed. For information on how this is done, see: Venipuncture.Your doctor may order only a cholesterol level as the first test, which will measure cholesterol and HDL cholesterol levels. You may not need more cholesterol tests if your cholesterol is in the normal range.You may also have a lipid (or coronary risk) profile, which includes:Low density lipoprotein (LDL or "bad" cholesterol)High density lipoprotein (HDL or "good" cholesterol)Total cholesterolTriglyceridesVery low density lipoprotein (VLDL cholesterol, though this is often calculated from the triglyceride level)People who also have high triglyceride levels may get a test called a direct LDL cholesterol (direct LDL-C).Other blood tests, such as C-reactive protein (CRP), may be added to the profile in some laboratories.How to prepare for the testOften, if you are only having a cholesterol level done, you can eat beforehand.If you are having a lipid profile, you should not eat or drink anything except water 9 - 12 hours before having your blood drawn.How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedWhy the Test is PerformedCholesterol blood tests are done to help you and your doctor better understand your risk for heart disease, stroke, and other problems caused by narrowed or blocked arteries.A lipid profile may be done:To screen all adults and children for high blood cholesterol and triglyceride levelsTo screen adults or children who have diabetes, high blood pressure, heart disease, stroke, or related problemsTo follow people who have had high cholesterol levelsADULTSSome national guidelines recommend having the first cholesterol test done at age 20. Everyone should have their first screening test by age 35 in men, and age 45 in women.People who have diagnosed with diabetes, heart disease, stroke, or high blood pressure should always have a cholesterol test done, no matter what their age.Follow-up testing should be done:Every 5 years if your results were normalMore often (about every year) for people with diabetes, high blood pressure, heart disease, stroke, or blood flow problems to the legs or feet.Every year if you are taking medications to control high cholesterol.CHILDRENNot all experts agree on when to first check cholesterol levels in children.Some experts recommend only screening children who have risk factors, such as a family history of high cholesterol or a family history of heart attacks before age 55 in men, and before age 65 in women.Others recommend screening all children, but many experts feel there is not enough evidence to recommend for or against cholesterol screening in children.Normal ValuesThe ideal values depend on whether you have heart disease or other risk factors. Your health care provider can tell you what your ideal results should be.The desired values in most adults are:LDL cholesterol: lower than 130 mg/dL (lower numbers are desired)HDL cholesterol: greater than 40 - 60 mg/dL (higher numbers are desired)Total cholesterol: less than 200 mg/dL (lower numbers are desired)Triglycerides: 10 - 150 (lower numbers are desired)VLDL: 2 - 38Talk to your health care provider about the ideal levels in children.Note: mg/dL = milligrams per deciliterNote: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.What abnormal results meanAbnormal values may be a sign that you are at increased risk for heart disease, stroke, and other problems caused by narrowed or blocked arteries.Any active illness, such as a flare-up of arthritis, can change your total cholesterol number. If you have had an illness in the 3 months before having this test, you should have this test repeated in 2 or 3 months.See: High cholesterol to learn more about the causes of high cholesterol levels.See also:Cholesterol and lifestyleCholesterol - drug treatmentWhat the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other.

What transports lipids throughout the body?
chilomiron and VLDL and HDL and LDL are carriers for lipids however in some cases if there were small they could be absorbed from intestine
The production of endogenous VLDL is decreased by?
The production of endogenous VLDL is decreased by a diet high in Omega 3 and exercise.
VLDL are poduced in which organ?
The liver.
What is the normal vldl level?
5-40
What does VLDL refer to on a blood test?
VLDL (very low density lipoprotein) is a type of "bad "cholesterol, helps cholesterol build up on the walls of arteries so laboratory test the amount of VLDL in your blood. Normal VLDL cholesterol level is between 5 and 40 mg/dL and high levels indicate a higher risk for heart disease, stroke, etc..
Which cholesterol level is not important?
VLDL CHLOESTELOL is bad for the body
How do you derive VLDL cholesterol?
Some divide triglyerides by 5.
What does vldl ldl and hdl do?
The codes LDL, HDL and VLDL are all related to cholesterol screening and blood tests. These measure the lipoprotein in the blood. There are many benefits to having this test done.
What does vldl cholesterol cal mean?
Very-low-density lipoprotein (VLDL) cholesterol is one of the three major types of lipoproteins. The other two are high-density lipoprotein (HDL) cholesterol and low-density lipoprotein (LDL) cholesterol. Each type contains a mixture of cholesterol, protein and triglyceride, but in varying amounts.LDL contains the highest amount of cholesterol. HDL contains the highest amount of protein. VLDL contains the highest amount of triglyceride, a blood fat. Like LDL cholesterol, VLDL cholesterol is considered a type of "bad" cholesterol because elevated levels are associated with an increased risk of coronary artery disease.It is important to know your VLDL cholesterol level. However, there is no simple, direct way to measure VLDL cholesterol. So VLDL cholesterol is usually estimated as a percentage of your triglyceride value. A normal VLDL cholesterol level is between 5 and 40 milligrams per deciliter.By lowering your triglyceride levels, you also lower your VLDL cholesterol levels. Healthy lifestyle changes such as losing excess weight and exercising regularly can help lower triglyceride levels. Also, avoid sugary foods and alcohol, which have a particularly potent effect on increasing triglycerides.
Is VLDL is a lipoprotein that delivers fat made in the liver to various tissues?
no it is actually chylomicrons
What does the medical abbreviation VLDL mean?
Very Low Density Lipoproteinvery low density lipoprotein.
What are the 4 major lipoproteins?
(See link below)Chylomicrons are the least dense of all the lipoproteins and are basically just big balls of fat (triglycerides), with a makeup of about 90 percent fat, a touch of phospholipids, some cholesterol, and a smidgin of protein.VLDL (very low-density lipoprotein) carries a great amount of fat, some phospholipids, and cholesterol. The high fat content of VLDL makes a large quantity of this lipoprotein in the blood undesirable.LDL (low-density lipoprotein, or "bad" cholesterol) has only a fraction of the fat and double the protein of VLDL and is very high in cholesterol. This lipoprotein carries the majority of cholesterol in the blood and is considered the unhealthy one.HDL (high-density lipoprotein, or "good" cholesterol) is a spherical blob of mostly protein (albeit a type different from that found in LDL), some cholesterol, phospholipids, and very little fat. The densest of all the lipoproteins, HDL is the healthy one.
