Blood biochemistry: total lipid

Synonym(s): Total triglyceride and cholesterol

Contributor(s): Kathleen P Freeman

Overview

  • Often measured when lipemic plasma noted in fasting animal.
  • Quantification involves measurement of serum triglycerides plus cholesterol.
  • Must be carried out after 12 hour fast.
  • Measured by spectrophotometry or enzymatic methods.
  • Lipemia may cause artefactual variation in other laboratory tests.

Tests

Methodologies

  • Chylomicron test: refrigerate an aliquot of serum overnight; chylomicrons float to the top.
  • Cholesterol measurement: several methods but enzymatic method most common.
  • Triglyceride measurement: spectrophotometric or enzymatic methods.
  • Lipoprotein electrophoresis: requires specialized equipment; lack of diagnostic specificity.

Validity

Sensitivity

  • Relatively high.

Specificity

  • Low.

Technique (intrinsic) limitations

  • Information regarding cause of hyperlipidemia or hypolipidemia.

Technician (extrinsic) limitations

  • Repeatable provided fasted animal.
