Test Code LIPD or LAB18 Lipid Panel With Reflex Measured LDL, Serum or Plasma

Important Note

Note: Unless the order specifies "Lipid Panel Without Reflex Measured LDL," the measured LDL will be performed in cases where the triglyceride is >800 mg/dL. This is due to the inability to calculate an LDL if the triglyceride level is >800.

If a reflex-measured LDL is not desired, order LIPN (LAB2211)

Note about fasting requirements: Fasting is no longer required. See the December 2020 LabWire (Resources section) for details. If a fasting triglyceride level is desired, the patient should fast for 12 hours before collecting a sample. The patient should be on a normal diet and maintain a stable weight for one week before testing. 

Profile Information

Test ID Reporting Name Available Separately? Always Performed?
CHOL Cholesterol Y Y
TRIG Triglycerides Y Y
HDL HDL Y Y
LDL, calc LDL - calculated result N Y*
NonHDL2 Non HDL Chol. (LDL+VLDL) Y Y
Chol/HDL Chol/HDL Ratio Y Y

*If the triglycerides result is > 800 mg/dL, the LDL - calculated result will not be performed. Instead, a measured LDL is reflexed and performed. 

Specimen Requirements

Container Type:

Optimal: Gold or Mint*

*For STAT requests

Acceptable: Red or Green
Optimal Collection Volume: 

4.5 mL; full tube
Specimen Minimum Volume:
  • Adults: 1 mL whole blood
  • Neonates: 1 microtainer (400-600 uL)
Collection Instructions:

Gently invert sample 5-6 times after collection.
Specimen Transport:

Refrigerate
Processing Instructions: 

1. If serum, allow the sample to clot for 30 minutes.

2. Centrifuge specimen within 2 hours of collection.

3. After centrifugation, specimen tubes without a gel barrier should have the serum or plasma aliquoted to a false bottom container.

4. Keep serum/plasma refrigerated until testing can be performed.

Specimen Stability

Specimen Type Temperature Time
Serum* Room Temperature 2 days
Refrigerated 7 days
Frozen 3 months

*Note: Heparinized plasma in gel separator tubes is less stable than serum and is only suitable for add-on testing up to 2 days following sample collection.

Specimen Rejection Criteria

Hemolysis Mild OK; Moderate OK; Gross Reject
Other Quantity not sufficient

Useful For

Monitoring of atherosclerotic disease.
