  Background: the stability of serum specimen during time storage is importance
in clinical and medical science researches in addition of diagnosis. Lipids are
organic molecules that classified into 8 classes: fatty acids, phospholipids,
glycerolipids, saccharolipids, polyketides, prenol lipids, sterol, and
sphingolipids. Lipid analysis (cholesterol, triglyceride, high density
lipoprotein, low density lipoprotein, very low-density lipoprotein) is a vital
tool for diagnosis of numerous disease such as cardiovascular disease.
follow-up the lipid profile progression is essential of numerous diseases.
Methods: a 72 apparently healthy individual were participated in current study
the serum sample was taken after 12-14 hours of fasting. The serum cholesterol,
triglyceride, high density cholesterol, low density cholesterol, and very
low-density cholesterol were determined. Results: there are no significant
value found in all groups when compared to control except triglyceride that was
significant after 24 hours of freezing.
