Comments:
Ketosis is a common feature in acutely ill patients. In subjects
suffering from starvation, acute alcohol abuse, or diabetes mellitus,
ketosis can result in severe life-threatening metabolic acidosis. The
presence and degree of ketosis can be determined by measuring blood
levels of β-hydroxybutyrate.
Ordinarily, β-hydroxybutyrate is the ketoacid present in the greatest amount in serum. It accounts for approximately 75% of the ketone bodies which also include acetoacetate and acetone. During periods of ketosis, β-hydroxybutyrate increases even more than the other two ketoacids (acetoacetate and acetone), and has been shown to be a good index of ketoacidosis, including the detection of subclinical ketosis.
In diabetics, the measurement of β-hydroxybutyrate as well as blood glucose can help to assess the severity of diabetic coma and help exclude hyperosmolar non-ketotic diabetic coma.
The β-hydroxybutyrate assay is specific for β-hydroxybutyrate and shows no cross-reactivity with acetoacetate or acetone.
