Biocompatibility Cost at 86% variants requiring the full panel: a worked example

This scenario runs the biocompatibility cost calculation on the strong side: 86% variants requiring the full panel, with every other input held at its documented default. A program lead sizing ISO 10993 biological evaluation cost before locking adhesive and housing materials for a skin-worn sensor.

The inputs for this scenario

  • Material-contact variants tested: 6 variants (unchanged)
  • ISO 10993 test panel price: 4,200 $ / variant (unchanged)
  • Variants requiring the full panel: 86 % (raised for this scenario; the documented default is 75)
  • Biological evaluation plan fee: 5,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total biocompatibility cost = variants x panel price x (% needing full panel) + BEP fee) to the inputs above produces each figure below.
  • At this operating point the engine returns 27,172 $ for total biocompatibility cost, the number this scenario is built around.
  • At this operating point the engine returns 4,529 $ / piece for biocompatibility cost per unit.
  • At this operating point the engine returns 21,672 $ for variable biocompatibility cost.
  • At this operating point the engine returns 5,500 $ for fixed biocompatibility cost adder.

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 11.36% above the baseline at 27,172 $.
  • Use it during design transfer or supplier changes to budget ISO 10993 testing before committing to a material set. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total biocompatibility cost: 27,172 $ (headline result)
