Qualitative in vitro cytotoxicity assessment in which a 1X (undiluted) test article extract in minimal essential media (MEM) is applied to a confluent L-929 mouse fibroblast monolayer and scored for cellular reactivity, per ISO 10993-5.
Sample Amount:
- 1 complete device, 30cm² (if >.5mm thickness);
- 1 complete device, 60cm² (if <.5mm thickness);
- 1 complete device, 2 grams (for powders/absorbable material only)
Estimated Turn-Around Time: 2 Weeks

Extraction
|
1 extract at 10 mL per extract. Extraction ratio per ISO 10993-12: 6 cm2/mL for material under 0.5 mm thick, 3 cm2/mL at 0.5 mm or thicker, or 0.1-0.2 g/mL where surface area is indeterminate. |
|
Acceptance criteria
|
Per ISO 10993-5, the extract is non-cytotoxic if the reactivity grade is 2 (mild) or less; a grade greater than 2, or a reduction of cell viability below 70% in the quantitative (MTT) assay, indicates a cytotoxic effect. |
