The Lipid 5 panel provides a comprehensive look at the essential fats circulating in your bloodstream. Total cholesterol reflects your overall cholesterol load, while LDL (“bad” cholesterol) shows how much artery‑clogging cholesterol is present. HDL (“good” cholesterol) helps clear excess cholesterol from the bloodstream, making higher levels protective. Triglycerides measure the fat your body stores and uses for energy, and elevated levels often signal metabolic stress or insulin resistance. The total‑cholesterol‑to‑HDL ratio ties these markers together, offering a powerful indicator of your overall cardiovascular balance. Together, these five markers form the foundation of understanding your heart health and metabolic function.
