The Limulus amebocyte lysate test is used to assess which kind of contaminants?

• A. Immunodeficiency
• B. Teratogens
• C. Bacterial pyrogens
• D. Carcinogens

Answer: (C)

Limulus amebocyte lysate testing targets bacterial endotoxins, the pyrogens released by many Gram-negative bacteria. Endotoxins trigger a specific cascade in the LAL reagent, causing a visible gelation or colorimetric change that signals contamination. This makes the test essential for ensuring that drugs, intravenous solutions, and medical devices are free of pyrogenic contamination. The other concepts listed—immunodeficiency, teratogens, and carcinogens—are not what this assay detects, so the test is best described as screening for bacterial pyrogens.
