Measuring Expired Isoprene in Human Breath During Exercise

Researchers have recommended isoprene to be used as a marker in human breath to assess blood cholesterol. The use of breath isoprene has been theoretically proved as an effective and non-invasive diagnostic tool in determining the variations in blood cholesterol levels in human.
