NGAL

A Neutrophil Gelatinase-Associated Lipocalin (NGAL) assay kit is a laboratory immunoassay (often ELISA) used to quantitatively measure NGAL protein levels in biological samples such as serum, plasma, urine, or other fluids. NGAL (also known as lipocalin-2 or LCN2) is a small protein associated with neutrophils and many other cell types that is released into circulation or excreted in response to tissue injury and inflammation.

🧪 What the NGAL Assay Measures

An NGAL assay kit typically uses antigen-specific antibodies to capture and quantify the amount of NGAL in a sample. These kits are available for human clinical samples and for research in other species. They provide a sensitive and specific measurement of NGAL concentration, which can be used as a biomarker read-out in clinical or research settings.

🧠 Why NGAL Is Useful Clinically

• Rapid response: NGAL rises quickly after tissue injury.
• Multiple sample types: It can be measured in serum/plasma, urine, and other fluids.
• Predictive value: Useful for assessing disease risk, severity, and sometimes prognosis.

🧩 Limitations and Considerations

• NGAL is not specific to one disease; levels go up with various inflammatory or tissue-injury states.
• Interpretation should be in the context of clinical presentation and other laboratory findings.
• Assay performance can vary by kit and sample handling; careful validation is important.
