LDL P (Low-density Lipoprotein Particle Number) Blood Test
LDL P (Low-density Lipoprotein Particle Number) Test (Labcorp)
This test measures the level of Low-Density Lipoprotein Particles (LDL-P) in a blood sample. LDL is also known as the "bad" cholesterol. Generally, higher LDL indicates a greater risk of heart disease. However, while a standard cholesterol test measure the amount of LDL, it does not look at the number of LDL particles. Studies have shown that a person's LDL particle number can be a greater indicator of their risk for cardiovascular disease than the LDL level by itself.
An LDL-P test is sometimes ordered along with or as a follow-up to a Lipid Panel Cholesterol test when a person has a family history of heart disease. It can also be ordered periodically to monitor a person's response to cholesterol medication.
LDL-P is also included as part of an NMR Lipoprofile test. The NMR is a comprehensive cholesterol test that includes a variety of measurements including LDL particle number and particle size.
Turnaround for this test is typically 1-3 business days.
