Evaluation of lipase activity in serum by radial enzyme diffusion

Area of Science:

• Biochemistry
• Clinical Chemistry
• Enzymology

Background:

• Serum lipase determination is crucial for diagnosing pancreatic diseases.
• Existing titrimetric methods for lipase assay have limitations in specificity.
• Differentiating pancreatic disease requires sensitive and specific diagnostic tools.

Purpose of the Study:

• To evaluate the efficacy of radial enzyme diffusion for serum lipase determination.
• To compare the diagnostic specificity of radial enzyme diffusion with a titrimetric method.
• To assess the utility of radial enzyme diffusion in identifying pancreatic disease.

Main Methods:

• Serum samples were analyzed for lipase activity using radial enzyme diffusion.
• Results from radial enzyme diffusion were correlated with a titrimetric reference method.
• Assay specificity was assessed in patient cohorts with and without pancreatic disease.

Main Results:

• Radial enzyme diffusion showed strong correlation with the titrimetric method in abnormal lipase ranges.
• The diffusion assay differentiated patients with pancreatic disease, unlike the titrimetric assay at normal limits.
• Pancreatic lipase was undetectable by diffusion assay in healthy individuals.

Conclusions:

• Radial enzyme diffusion is a specific and reliable method for serum lipase determination.
• This assay aids in the specific diagnosis of pancreatic disease, even with borderline titrimetric results.
• The method offers improved diagnostic accuracy for pancreatic conditions.
