Test Method
Test Description
Recommended Sample Size*
Turnaround Time*
LAL120
Recombinant Cascade Reagent (rCR) Endotoxin Testing
rCR Kinetic Chromogenic Testing at a sensitivity of 0.001 EU/mL. Includes validation to confirm the sample matrix does not interfere with endotoxin detection.
Sample Size
Medical devices: No less than 10 samples; Pharmaceuticals: 3 samples (beginning, middle, end of batch); Water: 5 mL preferred (1 mL minimum).Turnaround Time*
4-6 days, with GLP & expedited options available
LAL155
Kinetic Method Suitability Assay
Typically performed for pharmaceutical products and other complex sample matrices to verify that the selected method can accurately and reliably detect endotoxins without sample-related interference.
Sample Size
VariableTurnaround Time*
7 days*Sample size and turnaround time are general guidelines. Actual requirements and timelines may vary based on product type, testing complexity, sample preparation needs, and regulatory considerations.
