Triglycerides are produced from the digestion and breakdown of fats in foods, as well as from the breakdown of other energy sources, such as carbohydrates. Triglycerides can be used as an immediate energy source or be stored for later use. Elevated triglycerides are associated with increased risk of cardiovascular disease, type 2 diabetes, metabolic syndrome, hypothyroidism, and pancreatitis.

Additional Information and Resources


Preparation Before Specimen Collection

  • Maintain a stable diet for 2 weeks before specimen collection.
  • Fast for 8 – 12 hours before specimen collection.
  • Do not consume any alcohol in the 24 hours prior to collecting your sample for this test.

Specimen Type



50 μL in a microtainer


Microtainer (regular blood tube)

Collection Method

This test requires a blood sample from a finger prick. All supplies for sample collection are provided in the kit.

  1. First wash and dry hands. Warm hands aid in blood collection.
  2. Clean the finger prick site with the alcohol swab and allow to air dry.
  3. Use the provided lancet to puncture the skin in one quick, continuous and deliberate stroke.
  4. Wipe away the first drop of blood.
  5. Massage hand and finger to increase blood flow to the puncture site. Angle arm and hand downwards to facilitate blood collection on the fingertip.
  6. Drip blood into the microtainer tube.
  7. Dispose of all sharps safely and return sample to the laboratory in the provided prepaid return shipping envelope.

NOTES: Avoid squeezing or ‘milking’ the finger excessively. If more blood is required and blood flow stops, perform a second skin puncture on another finger. Do not touch the fingertip.

Specimen Storage

Maintain specimen at temperatures between 2°C and 30°C during storage and transport.

Specimen Stability

Blood samples can be refrigerated or kept at room temperature for up to 7 days.
