ANCHOR LEAD: SOMETIMES TAKING A BLOOD LEVEL OF CHOLESTEROL AFTER EATING IS GOOD, ELIZABETH TRACEY REPORTS
Most of the time, your doctor will ask you not to eat before having your blood drawn to measure cholesterol. But Roger Blumenthal, director of the Cicarrone Center for Preventive Cardiology at Johns Hopkins, says sometimes the values drawn after eating are very revealing.
BLUMENTHAL: People should realize that even results done when someone has eaten breakfast or lunch have value, because the normal person won’t shoot up their triglycerides very high even if they’ve eaten. If you have a patient that does they’re clearly predisposed to higher triglycerides, diabetes and the metabolic syndrome. Actually non-fasting triglycerides may have a lot of prognostic importance also. But for most people for standardization we still generally prefer patients skip breakfast or just have a modest intake before they get their bloods drawn. :32
So make sure you know what your doctor is trying to measure to determine if you can eat or not before visiting the lab. I’m Elizabeth Tracey reporting.
