Erectile Dysfunction Panel

Eight tests: Total Testosterone + Free Testosterone (T) + SHBG (hormones), Estradiol (estrogen balance — elevated E2 in men can lower libido and impair erections), Prolactin (pituitary cause), TSH (thyroid), A1c (diabetes — major ED cause), and Lipid Panel (vascular disease drives ED in older men). Together they identify the major treatable causes.

Erectile arteries are smaller than coronary arteries — they show vascular disease 3-5 years before a heart attack. New-onset ED in a man over 40 warrants a cardiovascular workup, not just a Viagra prescription. The Lipid Panel + A1c components catch the most common vascular and metabolic drivers — add the Heart Health Panel for hs-CRP and ApoB if cardiovascular risk is the main concern.

Yes. ~30% of men with ED have low testosterone contributing to the problem. PDE5 inhibitors work less well when T is low. Identifying low T first (and treating it before or alongside PDE5 inhibitors) gives better outcomes than Viagra alone.

On TestWell, the ED Panel starts at $114.99 (Quest; $149.99 at Labcorp, which prices these markers higher). Ordering the same tests separately would be about $240. Quest Direct lists comparable bundles at $280, walk-in hospital labs and urology offices typically bill $500-800 for the same biomarkers without insurance.

Yes — 9-12 hours fasting (water only) and morning draw (7-10 AM). Fasting needed for Lipid Panel and A1c; morning draw needed for accurate testosterone (which peaks early).

Then ED is likely psychological (anxiety, depression, relationship stress) or due to specific medications (SSRIs, beta-blockers, finasteride). PDE5 inhibitors usually work well in this case. Counseling or medication review with a primary care physician is the next step.

If you're 40+ with new ED, consider it. The Heart Health Panel adds ApoB, Lp(a), and additional CV markers. Some men benefit from a coronary calcium (CAC) scan as well — ED can be the first symptom of CAD.

Erectile Dysfunction Panel results are typically ready in 2–5 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.

Keto and high-protein diets, oral contraceptives and estrogen and time of day can change an Erectile Dysfunction Panel result without anything being wrong. Keto and high-protein diets can raise LDL Cholesterol and HDL Cholesterol and can lower Triglycerides and Hemoglobin A1c — recheck with ApoB; discuss cardiovascular risk rather than dismissing the rise as 'diet noise'. Oral contraceptives and estrogen can raise SHBG and Triglycerides and can lower Total Testosterone and Estradiol — expected; interpret testosterone with it. Time of day can shift Total Testosterone and TSH and can raise Prolactin — draw 7–10 a.m.; confirm a low result with a second morning draw. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.

Order the Erectile Dysfunction Panel online from TestWell for $114.99 (plus a $6 per-order lab processing fee) — no doctor's visit, referral or insurance needed. A licensed physician authorizes the order, then you walk into any Quest or Labcorp patient service center near you for the draw (the lab locator on our site lists the closest ones by ZIP code), and results arrive in 2–5 business days.
