Lipid Panel Explained: LDL, HDL and Triglycerides
[Glossary · How doses act in the body]

Lipid panel

Also called lipid profile, cholesterol test, cholesterol panel · Reviewed

Definition: A lipid panel, or lipid profile, is a blood test that measures the fats in your blood: LDL ("bad") cholesterol, HDL ("good") cholesterol, total cholesterol and triglycerides. MedlinePlus says high LDL raises the risk of heart disease because it helps build plaque in the arteries. High cholesterol usually has no symptoms.

Why it shows up on labs when you track doses

The Xyosted label says testosterone can change the serum lipid profile and says to monitor it periodically, especially after starting. The Depo-Testosterone label says serum cholesterol may increase during androgen therapy and lists dyslipidemia among reported reactions.

The anastrozole label says total cholesterol may increase and to consider cholesterol monitoring.

Reading the report

  • Units. MedlinePlus says cholesterol is usually reported in milligrams per deciliter (mg/dL).
  • Calculated vs direct LDL. If LDL says "calculated", it was estimated from total cholesterol, HDL and triglycerides rather than measured directly.
  • Adult lines. MedlinePlus lists total cholesterol under 200 mg/dL and LDL under 100 mg/dL as healthy levels for adults, with HDL of 60 mg/dL or more as best. It says a healthy level for you depends on age, family history and other risks.

Each lab sets its own reference range, so read your result against the range printed on your own report, and talk with your clinician about what it means for you.

Common mix-ups

  • Fasting. The CDC says you may need to fast 8 to 12 hours; MedlinePlus says 9 to 12. Ask your provider how to prepare.
  • How often. The CDC says most healthy adults are checked every 4 to 6 years, and people with heart disease, diabetes or a family history more often.
