How do you calculate biocompatibility testing cost?

Multiply the number of contact-material variants by the full panel price, scale by the percent that actually need the full panel, then add the fixed BEP fee. Six variants at $4,200, 75% needing full panel, plus a $5,500 BEP, totals $24,400.

What is a biological evaluation plan (BEP) fee?

The BEP is the ISO 10993-1 document that justifies which tests are and are not needed, usually authored by a toxicologist. It is a fixed cost - $5,500 in this example - that you pay once regardless of how many variants you test.

Why divide total cost by variants?

Cost per variant ($4,067 here) lets you compare material options on an even footing and decide whether consolidating to fewer contact materials is worth it, since the fixed BEP fee is spread across every variant tested.

What does the 'variants requiring full panel' percentage mean?

Not every material needs the complete ISO 10993 battery; chemical characterization or read-across to prior data can waive endpoints. At 75%, three-quarters of variants incur the full $4,200 panel, which is why variable cost is $18,900 rather than $25,200.

How can I reduce biocompatibility cost on a wearable sensor?

Reduce the number of distinct contact materials, use master-file or read-across data to lower the full-panel percentage, and reuse one BEP across variants. Dropping the 75% capture or cutting one variant both move the $24,400 total directly.

Is this the same as the total regulatory cost?

No. This covers ISO 10993 material biocompatibility only. It excludes clinical, electrical safety (IEC 60601), EMC, and cybersecurity testing, so it is one line in a broader submission budget.

Wearable Medical Sensors calculator

Biocompatibility Cost Calculator

Biocompatibility cost estimates what it takes to qualify the skin-contacting materials of a wearable medical sensor under ISO 10993, combining lab panel spend with the fixed biological evaluation plan (BEP) fee. Regulatory and program managers use it because contact materials - adhesives, housings, electrodes - each may need cytotoxicity, sensitization and irritation testing, and panel prices run into the thousands per variant. Not every variant needs the full panel: a chemical-characterization or read-across strategy can waive some testing, which this model captures with a capture percentage. Getting this number right early prevents a nasty surprise in the design-transfer budget.

What this calculator does

Estimate the biocompatibility testing spend for wearable medical sensor skin-contact materials across all evaluated variants.
A program lead sizing ISO 10993 biological evaluation cost before locking adhesive and housing materials for a skin-worn sensor.
It computes total biocompatibility cost as variants times panel price times the fraction needing a full panel, plus the fixed BEP fee, and divides by variants for a per-variant cost.

Formula used

Total biocompatibility cost = variants x panel price x (% needing full panel) + BEP fee
Cost per variant = total biocompatibility cost / variants tested

Inputs explained

Material-contact variants tested:
ISO 10993 test panel price:
Variants requiring the full panel:
Biological evaluation plan fee:

How to use the result

Use it during design transfer or supplier changes to budget ISO 10993 testing before committing to a material set.
It treats the full panel as one blended price; real ISO 10993 endpoints (cytotoxicity, sensitization, systemic toxicity, etc.) vary widely in cost, so a variant needing only a subset can be far cheaper than the blended figure implies.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
