GTC’s Liquid Trace™ Test Overview
GTC’s Liquid Trace can significantly reduce the need for bone marrow biopsies for hematology patients
cfDNA Only Provides Partial Results
Get Comprehensive Results by Combining cfRNA with cfDNA
Liquid biopsy in its current form is dependent on cfDNA analysis; this method likewise presents multiple challenges. These include variations in DNA shedding between tumors as well as low sensitivity (especially in early-stage cancer), difficulty in detecting fusion genes (i.e., chromosomal translocations leading to the expression of chimeric mRNA from two genes), and inability to reflect the numerous biological processes that modify RNA expression levels, such as alternative splicing, stability, and allele-specific methylation. The latter limitation is critically important as recent studies have shown that RNA testing provides another level of biological information regarding the tumor and its microenvironment.

GTC’s Liquid Trace is a pan-cancer test evaluating cfRNA and cfDNA providing highly informative data that can be used for diagnoses, evaluating the host immune response, and identifying biomarkers for predicting responses to various therapies.
The Benefits of cfRNA
RNA sequencing has proven to be more sensitive in detecting mutations in clinical studies. This research is consistent with GTC’s findings that cfRNA has increased sensitivity over cfDNA alone. More specifically, cfRNA allowed GTC’s Liquid Trace to detect more mutations and fusions in hematologic and solid tumor samples, which may be undetected by conventional cfDNA.
