Study challenges lipid test fasting

The long-assumed need for fasting before LDL-cholesterol testing has been challenged by a US study showing non-fasting LDL-C levels provide equally good cardiovascular risk prediction.

Based on a 14-year follow-up of more than 16,000 middle-aged men, New York researchers found that both non-fasting and fasting (eight hours) LDL-cholesterol levels had similar prognostic value for increased all-cause and cardiovascular mortality.
