Understanding Lab Tests for Lysosomal Storage Diseases
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Lysosomal storage diseases are a group of rare inherited metabolic disorders caused by defects in lysosomal function. These genetic conditions result from enzyme deficiencies that prevent lysosomes from properly breaking down cellular waste, leading to harmful accumulation of substances within cells.
Recommended Test
Lysozyme
This test measures lysozyme levels in the blood, which can become elevated in lysosomal storage diseases due to defects in lysosomal function. Elevated lysozyme levels may indicate cellular dysfunction associated with these rare inherited metabolic disorders and can serve as a supporting marker during the diagnostic process.

Role of Blood Testing in Lysosomal Storage Diseases
While definitive diagnosis of lysosomal storage diseases typically requires specialized enzyme activity tests and genetic testing, blood tests measuring specific markers can provide valuable supporting evidence. These tests help identify biochemical changes associated with lysosomal dysfunction and can guide further diagnostic evaluation.
Understanding Test Results
Abnormal lysozyme levels alone cannot definitively diagnose a specific lysosomal storage disease, but they can indicate the need for further specialized testing. Healthcare providers will interpret results in conjunction with clinical symptoms, family history, and additional diagnostic tests to reach an accurate diagnosis.
Important Considerations
