Biocompatibility Cost at 54% variants requiring the full panel: a worked example

This worked example runs the biocompatibility cost numbers for a tougher week than the baseline: 54% variants requiring the full panel instead of the typical 75%. Estimate the biocompatibility testing spend for wearable medical sensor skin-contact materials across all evaluated variants.

The inputs for this scenario

  • Material-contact variants tested: 6 variants (held at the documented default)
  • ISO 10993 test panel price: 4,200 $ / variant (held at the documented default)
  • Variants requiring the full panel: 54 % (the input this scenario stresses; the baseline uses 75)
  • Biological evaluation plan fee: 5,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total biocompatibility cost = variants x panel price x (% needing full panel) + BEP fee.
  • Total biocompatibility cost works out to 19,108 $ at these inputs, and this is the headline figure for the scenario.
  • Biocompatibility cost per unit works out to 3,185 $ / piece at these inputs.
  • Variable biocompatibility cost works out to 13,608 $ at these inputs.
  • Fixed biocompatibility cost adder works out to 5,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where variants requiring the full panel sits at 75% and the headline result is 24,400 $, this scenario comes in 21.69% below the baseline at 19,108 $.
  • Use it during design transfer or supplier changes to budget ISO 10993 testing before committing to a material set. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total biocompatibility cost: 19,108 $ (headline result)
  • Biocompatibility cost per unit: 3,185 $ / piece
  • Variable biocompatibility cost: 13,608 $
  • Fixed biocompatibility cost adder: 5,500 $
