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.

Additional Specimen Collection Information

Collect blood in a lithium heparin, green-top or red-top tube from a fasting patient. 12 hour fast is recommended. PST and SST (gel tubes) are acceptable. Serum or plasma should be separated from contact with the cells within 2 hours of collection. Specimens not centrifuged within 4 hours of collection may be rejected. Refrigerate the specimen if unable to assay within 8 hours of collection. Hemolyzed specimen (>2+) is not acceptable.

Limitations

Patient venipunctured immediately after or during the administration of Metamizole (Dipyrone) may
lead to falsely low results for Triglyceride. Venipuncture should be performed prior to the administration of Metamizole.
