Bacterial Endotoxin (LAL)

What this test measures

Bacterial endotoxin (LAL) testing measures endotoxin in your submitted sample using a kinetic chromogenic Limulus Amebocyte Lysate procedure informed by USP <85> compendial guidance. Results describe the analyzed sample only — not other vials, batches, suppliers, or future production. An endotoxin result does not establish sterility, absence of viable microorganisms, or suitability for administration.

What you receive

A Certificate of Analysis delivered electronically when testing is complete and results are released. Endotoxin results appear on the report only when this service was ordered for the analyzed sample.

Testing methodology

This service uses kinetic chromogenic LAL measurement informed by USP <85>. It does not include peptide identity, chromatographic purity, or net peptide content. Order it as a standalone test (one order = one sample), or add it during checkout when ordering Peptide Analysis or Peptide Blend Analysis for a compatible sample.

Sample requirements

Exact quantity depends on the test and sample matrix. After payment, VialTests provides submission instructions for your order. The laboratory analyzes the sample as received.

Important limitations

Endotoxin testing is not a sterility test. A reported endotoxin measurement — including a low or non-detected result — does not prove that a sample is sterile, pyrogen-free for administration, or safe for injection.
