LAL (Lysate of Limulus Amaebocytes) test

Regulatory reference: USP85.
Claim: Absence of bacterial endotoxins
Application field: Medical devices: raw ingredients and finished products.
Description of the test: Lysate of limulus amaebocytes (LAL) is an acqueous extract obtained by Limulus polyphemus amaebocytes. The LAL reacts strongly to endotoxins in Gram-negative bacterial membranes (lypopolysacchartides), resulting in coagulation. This property is exploited in the LAL test to detect endotoxins.

Skin tolerability test under dermatological supervision

Regulatory reference: Guidelines to Commission Regulation (EU) No 655/2013
Claim: Dermatologically tested
Application field: Heating and cooling medical devices and cosmetic products.
Description of the test:
  • Measurement at T=0 before the application and after a preset duration agreed upon with the sponsor;
  • Temperature control using an infrared non-invasive thermometer;
  • Evaluation of the erythemal response through skin colorimetry using a Mexameter® MX18 colorimeter (Courage-Khazaka GmbH – Germany);
  • Evaluation by clinical experts of the general conditions of the skin and epidermal tolerability during use;
  • Subjective evaluation through predefined questionnaire with numerical score system (visual analogical scale) and judgement of the tolerability and heat/chill feeling as perceived during the application of the product;
  • Comparative photography with colorimetric reference captured with a 100 mm macro objective and normalization of the color with coaxial circular flash.
