Healthcare professionals measure urinary NGAL levels using immunoassay techniques to detect and monitor kidney injury using NGAL. NGAL, a protein, is produced and released by various cells, including neutrophils (a type of white blood cell) and epithelial cells of the kidneys. NGAL serves as an early marking of kidney injury or insult, playing a role in the assessment and early detection diagnosis of acute kidney injury (AKI).When the kidneys are injured or under stress, NGAL levels increase rapidly in both blood and urine. Urinary NGAL Laboratory tests can measure levels to detecting and monitoring kidney injury. This will be especially valuable for early identification of. AKI, allowing for timely intervention and management.
