ALB and Protein-losing enteropathy: However, a recent study showed that the intensity of abnormal tracer activity does not always correlate with disease severity as explained by the fact that protein-losing enteropathy is characterized by nonselective depletion of all plasma proteins, and the disease severity is affected by turnover rates of various types of proteins, such as albumin and immunoglobulin.99mTc albumin scintigraphy visualizes only the depletion of albumin and not all plasma proteins, thereby not making it the ideal tracer for quantification of severity.12These were the limitations of our study.
