Leptin, Quantitative by Chemiluminescent Immunoassay
Also known as: LEP
Use
The quantitative measurement of leptin levels in the serum is a useful biomarker for diagnosing and understanding conditions associated with leptin resistance and obesity-related disorders. This assay helps physicians in assessing leptin levels in patients, which can provide insights into potential metabolic conditions or hormonal imbalances. Precise measurement of leptin can assist in understanding the physiological and pathological states related to energy expenditure, appetite control, and body weight regulation.
Special Instructions
Patients are required to fast overnight before the collection of the specimen to ensure accuracy of the test results.
Limitations
This laboratory-developed test has not been cleared or approved by the US Food and Drug Administration and is intended for clinical purposes only. It is not suitable for establishing leptin levels in infants and children under 18 years of age due to undefined reference intervals. Additionally, non-fasting specimens as well as icteric or severely hemolyzed specimens could yield inaccurate results requiring careful attention during sample collection and handling.
