Limitations

If triglycerides >400 mg/dL, LDL cannot be calculated
accurately by the Friedewald formula. Some women on estrogens and high
estrogen oral contraceptives have an increase of triglyceride.

Increases occur with pregnancy, similar to those with oral
contraceptives. The most common cause of triglyceride increase is
inadequate patient fasting.

Hypertriglyceridemia is associated with use of thiazide
diuretics and ?-adrenergic blocking agents;

Measuring range: 8.85 to 885
mg/dL.

Patient Preparation

Patient should be fasting 12 to 14 hours.

The patient should be on a stable diet two weeks prior to
collection of blood.

Reasons for Rejection

Nonfasting specimen; specimen collected in a glycerinated
tube; improper labeling
