Zeiss · Humphrey HFA · Used market pricing intelligence
Median is the primary statistic — used clinical pricing is full of outliers and the median ignores them.
No comp data yet. Collecting listings.
Clinical Asset Index aggregates listing data from eBay, GovDeals, DOTmed, HiBid, LabX, and PublicSurplus daily. Each listing is classified by type (complete system, major module, part / accessory, for parts / repair). Medians and ranges are computed only within peer groups — a complete system is never averaged with parts. Confidence thresholds: comps ≥ 0.65; deal-feed device-match ≥ 0.75 and classification ≥ 0.65. Median is the primary statistic; the mean is shown only as a small secondary number because outliers dominate this market. Data is directional — always verify independently before purchase.

Clinical Asset Index provides observed market intelligence — not an appraisal, not medical or regulatory advice. Always verify device condition, service history, regulatory status, and seller claims before purchase.
Independent of, and not endorsed, sponsored, certified, or authorized by — and not an agent of — any marketplace, manufacturer, or source. Market Index values are estimates based on observed listing data and do not represent appraisals or guaranteed sale prices.
