Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Lipids, including cholesterol, are a diverse group of organic molecules that are insoluble in water but soluble in organic solvents. They play a vital role in numerous physiological processes, including cell membrane structure, energy storage, and hormone synthesis. In the bloodstream, lipids are transported as lipoproteins, which are water-soluble complexes composed of two main structural components:
Lipoproteins are classified by their density, which is determined by the relative proportion of proteins to triglycerides. From lowest to highest density, the main classes include:
Chylomicrons (CM), very-low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL).
Elevated levels of atherogenic lipids—particularly LDL cholesterol, VLDL, triglycerides, and lipoprotein(a) [Lp(a)]—are well-established, independent risk factors for the development of coronary artery disease (CAD). International cardiovascular guidelines consistently emphasize the clinical importance of assessing serum lipid fractions, including total cholesterol, LDL-C, HDL-C, non-HDL-C, VLDL-C, Lp(a), and triglycerides, in evaluating and managing cardiovascular risk.
Accurate quantification of these lipid parameters is essential for risk stratification, diagnosis, and monitoring of lipid-lowering therapies aimed at reducing cardiovascular events.

Statement on Medical Necessity
All ordered tests should be medically necessary for the diagnosis or detection of disease, illness, impairment, symptom, syndrome, or disorder and the results should be used in the medical management and treatment decisions for the patient. Solaris requires ICD-10 codes with each order for lab testing and both the tests ordered and the diagnosis should be documented in the provider’s medical record for the patient. The United States Department of Health and Human Services, Office of Inspector General, takes the position that a provider who orders medically unnecessary tests may be subject to civil penalties.
Panels and Profiles
Solaris offers Providers the convenience of ordering test combinations in a group at times with the flexibility to choose appropriate test(s) for individual patients. Providers should only order those tests that he or she believes are medically necessary for each patient, and a lesser inclusive profile or individual tests should be ordered if not all tests in the test combination/profile are medically necessary. All tests offered in a test combination/profile may be ordered separately as individual tests. Solaris encourages clients to contact their Solaris representative if the testing configurations shown do not meet individual needs for any reason, or if some other combination of procedures is needed.
CPT Codes
CPT Codes listed are in accordance with Current Procedural Terminology, a publication of the American Medical Association. CPT codes are the responsibility of the billing party and are listed here for informational purposes. Correct coding may vary from one carrier to another. Solaris may bill specific carriers using codes other than what is shown.
