Lipid Cascade With Reflex to Lipoprotein Particle Assessment by NMR (Without Graph)
Use
The lipid cascade supports risk assessment and management of patients who present with cardiometabolic risk (CMR) factors (e.g., elevated blood pressure, abdominal obesity, insulin resistance (IR), lipoprotein abnormalities and elevated blood glucose).
Special Instructions
Not provided.
Limitations
If triglyceride level is >800 mg/dL, LDL cholesterol will not be calculated. The NMR lipoprotein analysis is an additional reflex test performed at an extra charge if criteria are met. Specimens cannot be stored at room temperature beyond a total preanalytical time of 24 hours, and specimens more than six days old are rejected.
