An erectile dysfunction (ED) panel is not a single standardized test. Instead, it usually refers to a group of laboratory tests ordered to identify possible medical causes of erectile dysfunction. An ED panel can help identify underlying causes such as:

• Low testosterone or other hormone imbalances

• Diabetes or prediabetes

• High cholesterol and cardiovascular disease

• Thyroid disorders

• Kidney or liver disease

• Anemia or other systemic illnesses

• An ED panel may include:

  • Total Testosterone (and sometimes Free Testosterone): Evaluates for low testosterone (hypogonadism), which can contribute to reduced libido and erectile dysfunction.

  • Blood Glucose or Hemoglobin A1c (HbA1c): Screens for diabetes or poor blood sugar control, a common cause of ED due to nerve and blood vessel damage.

  • Lipid Panel: Measures cholesterol and triglycerides. High cholesterol can narrow blood vessels and reduce blood flow to the penis.

  • Thyroid Function Tests (TSH ± Free T4): Identifies thyroid disorders that may affect sexual function.

  • Prolactin: Elevated prolactin levels can suppress testosterone production and contribute to ED.

  • Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH): Help determine whether low testosterone is due to a problem with the testes or the pituitary gland.

  • Complete Blood Count (CBC): Checks for anemia or signs of infection that may contribute to fatigue or sexual dysfunction.

  • Comprehensive Metabolic Panel (CMP) or Kidney/Liver Function Tests: Evaluates kidney and liver health and electrolyte balance, which can affect hormone metabolism and overall health.
