Do You Have To Fast For Lipid Screen
Should I fast before a cholesterol/lipid test? My nonfast cholesterol was recently high, but 6 months ago a fasting was square in the normal range?
Fasting is best: Hi. All the normal ranges for cholesterol, triglycerides, HDL, LDL, non-HDL, etc are based on fasting values. Normative values for post-challenge (i.e., non-fasting) lipids are not established. Actually, cholesterol changes very little with eating, whereas triglycerides may show a dramatic response depending on what is eaten. But yeah, do it fasting for the best info. ...Read more
I was suppose to fast 8 hours for a lipid profile but after big meal I actually fasted 21 hours. Will That Make Results Higher Or Lower?
Accurate: That's a long fast, but it should have led to accurate results nonetheless. ...Read more
I've been told to fast for 12 hrs before I get a lipid test. That doesn't include water does it? I cant do 12 hrs without water, food & juice no problem
Nothing: The information from a non fasting is just as good if not even better than a fasting lipid profile. In general your cholesterol is not affected by food although your triglyceride maybe higher but not much unless you have abnormal profile. The food you take is like a stress test to your body which will unmask any problem with handling fats. ...Read more
Definitely: A fasting lipid panel is what is needed to get reliable numbers, especially if they are being used to risk stratify you and/or calculate your lifetime risk of heart disease. 10-12 hours of no food, but may stay hydrated morning of test with water. ...Read more
Perhaps: Fasting status does not affect HDL cholesterol or total cholesterol mrasurements. After eating triglyceride (tg) levels increase. Since LDL cholesterol is calculated (total cholesterol minus (triglyceride/5 + HDL cholesterol)) non-fasting status makes LDL cholesterol measurements unreliable. If tg is elevatd (>150) I recommend re checking a fasting lipid profile. ...Read more
Actually: It is best to only drink water. ...Read more
Is it really necessary to fast for a lipid panel? My blood sugar will be rock bottom& the parkn garage & million mile walk to drs office is too much
Lab testing: To minimize variables that may affect lab results, it is standard practice to do fasting lab work. For a lipid panel, the triglyceride component is very sensitive to ingestion of food. Drinking plain water will not affect most lab results but ask your md first. ...Read more
Predicts events.: Lipid profile tells you about risk for future heart / blood vessel disease. Smoking, hypertension, diabetes and lipids are modifiable risk factors. Non modifiable risk factors are male sex, getting older and having family history of early heart disease. At your age there is virtually no contribution of lipids to mortality within the next 20 years unless numbers very high or many risk factors. ...Read more
Routine blood test: It is better to have a high HDL and a low LDL. HDL is the good and LDL is the bad cholesterol. Doctors want a patient's total cholesterol divided by HDL to be less than 3.0. Avoiding animal fats should lower one's LDL. One's triglycerides (TG) should not be high either. Avoiding sugar and avoiding simple carbohydrates should lower one's TG. ...Read more

Anti cardiolipin: You might be asking about anti-cardiolipin antyibodies. Anti-cardiolipin antibodies (aca) are antibodies often directed against cardiolipin and found in several diseases, including syphilis, antiphospholipid syndrome, livedoid vasculitis, vertebrobasilar insufficiency, behçet's syndrome, idiopathic spontaneous abortion and systemic lupus erythematosus (sle). ...Read more
Small intestine: Lipids are digested in the small intestine and absorbed with the assistance of bile which acts as an emulsifier, pancreas secretes lipase to breakdown some lipids and the small intestinal lining have enzymes at the "brush border" and certain shorter length fats can be absorbed directly in the intestines. Fats are then repackaged in the liver after digestion. ...Read more
No more than 10 ml: About one ml of serum is needed for the test and 4-5 ml will usually suffice. ...Read more
Lipoprotein Estimate: A lipid profile measures blood cholesterol and triglycerides (tg) carried inside lipoprotein particles (vldl, ldl, hdl). Tg is used to estimate vldl, while ldl-c and hdl-c estimate LDL and HDL particle levels. Current nih and national lipid association (nla) recommendations are that all children between 9 and 11 years of age should have screening lipid testing performed. ...Read more
Lipid checks.: Depends on your levels, really. A statin will generally require up to six weeks to make an impact on your numbers (and on your liver function indices). So the first check after initiation of the statin should be at six weeks. After that, would check every six weeks to six months depending on your levels. The impact on the liver tends to be an early effect. ...Read more
Fats vs Lipoproteins: The lipid panel=measurements of cholesterol, triglycerides & Apo-A (of HDL particles) to estimate cholesterol within both High-Density Lipoprotein (HDL) & Low-Density Lipoprotein (LDL) particles in water outside cells. It does not measure actual LDL or HDL particle concentrations, the key issue driving arterial disease: heart attack, stroke & peripheral arterial disease. See: http://goo. Gl/NmdIfm ...Read more
Variable: According to the 2013 American Heart Association guidelines: never. Most doctors will check 6 weeks after you start to see the effect and check the liver. It is recommended that one should not "treat to target" any more, meaning that just being on a statin is protective and attempting to reach a certain pre-determined low level becomes counter-productive. ...Read more

Lipid Definition: Lipids are fats. They are carried throughout the body in lipoproteins. Lipids have names like cholesterol, triglycerides and phospholipids. They are essential for life, yet when elevated to pathologic levels, or when seen in the setting of other cardiovascular risk factors such as diabetes or high blood pressure can cause heart disease or in the case of triglycerides, pancreatitis. ...Read more
Worth a try.: If your cholesterol numbers have been within acceptable ranges, it couldn't hurt to try to reduce the dose of a statin. Assuming, of course, that you have changed things otherwise to keep the numbers down, such as maintaining an exercise routine, changing your diet or losing weight. But it's always better to get by with less medication when possible. ...Read more
