Development of a Pediatric Tuberculosis Diagnostic Test

A lipoprotein diagnostic marker for TB disease ideal for a simple diagnostic assay from a finger prick blood or serum


The inadequate sensitivity of available organism-based TB diagnostic tools in children, the wide spectrum of disease observed in children, and the non-specific signs and symptoms especially in young and HIV-children, contribute to diagnostic delay and missed opportunities to detect childhood TB.

Technology Overview:

Researchers at Stony Brook have identified changes in a serum lipoprotein that result from a combination of host and TB pathogen activity. The MTB-modified lipoprotein (TLP) is thereby a more specific diagnostic marker for TB disease than the conventional host markers. Development of antibodies against the TLP marker enables the production of a simple in-vitro diagnostic (IVD) assay for pediatric tuberculosis using as finger-prick blood or serum.
