This study demonstrates strong and significant correlations between fasting and non-fasting blood tests for several metabolic indicators. These findings suggest that it may be acceptable to use non-fasting bloods to assess insulin resistance in epidemiological studies. This would avoid a number of difficulties inherent in asking participants to fast overnight and may remove one of the barriers to participation in these studies.
The adipokine measurements were the most stable measures between fasting and non-fasting samples. Non-fasting levels of leptin, adiponectin, and the leptin:adiponectin ratio were not significantly different and were very strongly correlated with the fasting values. ...
