Test Code LIPN Lipid Panel Without Reflex Measured LDL, Serum or Plasma

Additional Codes

LAB2211

Methodology

Cholesterol and Triglycerides - Spectrophotometric

HDL - Spectrophotometric with Selective Inhibition

Specimen Requirements

Container Type:

Optimal:

Inpatient: Mint

STAT: Mint

Outpatient: Gold 

Acceptable: Red Top or Green Lithium Heparin.

 
Optimal Collection Volume: 

A full tube is optimal for all blood draws.  Not only does it give the correct ratio of anticoagulant or clot activator to blood, a full tube allows for efficient automated testing and provides residual sample for any repeat, add on or reflex tests.   Please note: In most cases, multiple test orders requiring the same tube type may be combined in one tube.   Do not draw a separate tube for each test.   For exceptions where a test has a larger sample volume requirement, it will be noted in this section.

 

The approximate volume of blood needed for this test is 1.0 mL of blood (0.5 ml of serum or plasma).
Collection Instructions:

Gently invert sample 5-6 times after collection.
Processing Instructions: 

1. Allow serum sample to clot for 30 minutes.

2. Centrifuge specimen within 2 hours of collection.

3. Specimen tubes without a gel barrier should have the serum or plasma aliquoted to a false bottom container after centrifugation.

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

 

Collection Instructions: Fasting is no longer required; see December 2020 Labwire article for details.   If desired to evalute the fasting Triglyceride level,  fasting (12 hours) is acceptable.  Patient should be on a normal diet and maintain a stable weight for 1 week prior to testing.
