Lipopolysaccharide Binding Protein (LBP) Unit Converter
Lipopolysaccharide Binding Protein (LBP) is an acute-phase reactant synthesized by the liver. Its central role in innate immunity is to bind to Lipopolysaccharide (LPS or endotoxin), a component of the outer membrane of Gram-negative bacteria. LBP then facilitates the transfer of LPS to CD14 receptors on macrophages, initiating a powerful inflammatory cascade.
Clinically, LBP is recognized as a highly sensitive and early biomarker for sepsis and systemic bacterial infection, rising rapidly within hours of endotoxin exposure. It is used in critical care and research to assess the severity of the inflammatory response and the presence of occult bacterial translocation. This converter facilitates switching between the SI mass unit (mg/L or µg/mL) and the molar unit (nmol/L).
SI Units / Mass
RecommendedMilligrams per liter (Numerically mg/L = µg/mL).
Molar / Mass Equivalents
Clinical Context
Reference Range (Healthy): LBP levels are typically low, around 1–5 mg/L (1–5 µg/mL).
Sepsis: LBP levels increase dramatically (often > 20 mg/L) within 4–6 hours of endotoxin exposure, making it one of the earliest signs of Gram-negative bacterial infection. The molar conversion relies on MW 58,000 g/mol: 1 mg/L ≈ 17.24 nmol/L.

Frequently Asked Questions & Tips
Yes. 1 mg/L is exactly equal to 1 µg/mL.
LBP is a more specific initial response to bacterial endotoxin, while CRP is a downstream response to a variety of inflammatory cytokines, including IL-6.
