Novel Saliva-Based PCR Assay Detects HIV Antibodies Earlier

An oral fluid-based test for human immunodeficiency virus (HIV) shows promise as a population-based screening tool. According to its developers, the test is easier to collect than blood but yields results that are just as reliable. More...

Tests Links Circulating Tumor DNA and Breast Cancer Survival

Cancer researchers used a liquid biopsy test for circulating tumor DNA (ctDNA) to profile cancer genomes from blood samples and predict survival outcomes for patients with metastatic triple negative breast cancer. More...

Molecular Test Adapted for Parkinson’s and DLB

Parkinson’s disease (PD), multiple system atrophy (MSA), dementia with Lewy bodies (DLB) (or Lewy body dementia) are called α-synucleinopathies due to the abnormal accumulation of aggregates of a protein called α-synuclein (αSyn) in the brain. More...

Genomic Sequencing Augments Diagnosis of Lymphoid Cancer

Lymphoid cancers include diffuse large B-cell lymphomas (DLBCL), follicular lymphoma (FL), and chronic lymphocytic leukemia (CLL). In recent years, several sequencing-based assays have been developed, but their clinical applicability and utility for patients with specific mutations still needs to be verified. More...
