Test Code TRIG TRIGLYCERIDES

Methodology

Colorimetric

Useful for evaluation of risk factors in individuals with elevated cholesterol values. Since cholesterol and triglycerides can vary independently, measurement of both is more meaningful than the measurement of cholesterol only.

Specimen Requirements

 

Submit only 1 of the following specimens:

 

Preferred:

Serum

Serum Gel Tube

Container/Tube: Serum gel tube(s)
Specimen Volume: 1 mL (minimum volume: 0.5 mL) of serum

Collection Instructions: Fasting (9-12 hours). Spin down within 4 hours of draw.

Note: Label specimen appropriately (serum).

 

Alternate:

Serum

Plain, Red-Top Tube

Container/Tube: Plain, red-top tube(s)
Specimen Volume: 1 mL (minimum volume: 0.5 mL) of serum

Collection Instructions: Fasting (9-12 hours). Spin down within 4 hours of draw.

Note: Label specimen appropriately (serum).

 

Alternate:

Plasma

Container/Tube: Green-top (lithium heparin) tube(s)

Specimen Volume: 1 mL (minimum volume: 0.5 mL) of plasma

Collection Instructions: Fasting (9-12 hours). Spin down within 4 hours of draw.

Note: Label specimen appropriately (plasma).

Day(s) Test Set Up

Monday through Sunday

Reference Values

Optimal: <150 mg/dL

Borderline high: 150-199 mg/dL

High: 200-499 mg/dL

Very high: >500 mg/dL

Note: Free (nonesterified) glycerol in serum is measured along with the glycerol from the hydrolysis of triglycerides and diglycerides. Certain clinical conditions (eg, diabetes mellitus and cardiac ischemia) show high endogenous free glycerol levels. Some drugs used in the treatment of lipemia also produce elevated glycerol levels. Triglyceride results from samples of such patients will not reflect actual serum triglyceride content.
