A new method for calculating the rate of "bad cholesterol" in the blood is born. It is more accurate than the old method and allows for blood samples from people who have not fasted before the exam.
A study, published Jan. 2 in Circulation, suggests that routinely routine fasting for cholesterol testing could be avoided in most people, making such screening more convenient.
The new method of calculating bad cholesterol, LDL-cholesterol, was developed by Seth Martin and his colleagues at John Hopkins Hospital in 2013.
Other US and foreign researchers have confirmed its greater accuracy on a set of more than one million five hundred thousand participants, and the new method has been adopted by at least one major national diagnostic company in the United States this year.
More accurate and practical
Although the new LDL-cholesterol calculation method is a little more complex, it can be done using information already collected in the blood sample to give a more accurate result.
Since fasting is no longer necessary with this method which is also more accurate, it becomes more convenient for patients because they can be dosed cholesterol anytime and do not need to come back for a second appointment if they ate.
”With our study, clinicians and patients can make better decisions because they are armed with more accurate test results, congratulates the author. Those who still use the Friedewald method need to be more careful in the interpretation, but in the meantime they can use our smartphone app until their lab is converted. "
