(PhysOrg.com) — Patients do not need to fast before having their cholesterol tested, a major study has found.

Have High Cholesterol? – You Better Start Lowering It Now! Select Cholesterol Reducing Options - CholesterolGuideline.info
Published in the Journal of the American Medical Association, it is hoped the report, involving two University of Glasgow experts, will inform guidelines on cholesterol testing in the UK.
Cholesterol tests are used as a key part of assessing a patient’s risk of cardiovascular problems. Fasting has been recommended as it had been thought the body needed enough time to digest food in the system and to clear any fatty particles from the blood. This was in order to produce an accurate reading of so-called “bad” cholesterol – or low-density lipoprotein(LDL).
However, Naveed Sattar, Professor of Metabolic Medicine and Chris Packard, an Honorary Professor in Developmental Medicine, both of Glasgow, together with researchers from the University of Cambridge, found that test results were just as accurate without fasting.
“After analysing data from 300,000 patients, the results were just as accurate if the patient had eaten before the test,” said Professor Sattar.
Lead researcher John Danesh, Professor of Epidemiology and Medicine at the University of Cambridge, continued: “For decades, people have been asked to fast overnight before their cholesterol tests. Our findings indicate that cholesterol measurements are at least as good – and probably somewhat better – when made without fasting.”
The study also adds to the ongoing controversy over whether testing for blood proteins called apolipoproteins is a more reliable way of predicting heart risk than cholesterol testing.
“The studies showed that analysing “good” cholesterol – or high-density lipoprotein (HDL) in conjunction with LDL was just as informative as testing for apolipoproteins AI and B. Furthermore our paper shows that once “bad” cholesterol and “good” HDL-cholesterol are known, using the levels of triglycerides or fat in the blood, as a means to predict the risk of heart disease, is unhelpful,” said Professor Sattar.
Professor Peter Weissberg, Medical Director of the British Heart Foundation, which funded the study, said: “Given the pressure the NHS is under, it is good news that doctors don’t need to spend money on setting up more sophisticated tests based on apolipoproteins. But the study underlines the importance of all GPs being able to measure HDL cholesterol as well as totalcholesterol, in order to make the best predictions about heart disease risk.”
Cardiovascular disease is the leading form of death in the UK and many other parts of the world.

Using blood or urine samples has been the standard for workplace drug testing for years. One of the country’s biggest laboratories says we may be looking at a better, more convenient testing method for some types of drug use.
Quest Diagnostics has released the details of a testing study that shows for the first half of 2009:
Quest’s reason for the higher number of hair-tests positives: Hair samples tend to show drug use going back further than urine samples — typically 90 days vs. one to three days.
The study also calls into question the size of the reported drop in drug use the last several years. For instance, urine tests show cocaine use is down 57% since 2005, but hair tests show only a 36% drop. For methamphetamines, urine tests show a decline of 64% for that same period, but hair tests show only a 55% drop.
Hair tests cost about twice as much as typical urine tests, Quest, notes.
Drug testing cocaine with hair samples is the gold standard. Urine testing can be scammed with simple tricks like drinking lots of water before the test.
Newer workplace drug tests using hair samples reveal 10 times as many job applicants and employees taking cocaine and methamphetamine than had been found in urine tests. Quest Diagnostics hair data for the first time shows that in the …

Oral drug tests use a swab of saliva taken from the test subject’s mouth as a sample to test for the presence of drugs. Because they are simple to adminster and much more diffcult to falsify than some other methods of drug testing such as urine analysis, oral drug tests are becoming very popular.Posted via email from hometestingkits’s posterous
