Reference Interval

Reference Values:

DESMOSTEROL

< or =2.0 mg/L
 

LATHOSTEROL

≤ 3.0 mg/L
 

CAMPESTEROL

≤ 7.0 mg/L
 

SITOSTEROL

≤ 5.0 mg/L
 

CHOLESTANOL

≤ 5.0 mg/L

Interpretive Data

A quantitative report of the patient's sterol profile and a Biochemical Genetics consultant's interpretation is provided for each specimen.

Cautions:
Reference ranges were derived using fasting specimens from healthy individuals. Sitosterol and campesterol values may be mildly elevated in individuals whose diets include foods with high concentrations of plant sterols, such as some vegetable oils and infant formulas.
