Improved salivary HCMV IgG antibody assays may be a viable option for serum testing
Correspondence between Cytomegalovirus IgG Levels Measured in Saliva and Serum Riis, JL. Et al. (2020) Journal of Clinical Medicine. ABSTRACT:Cytomegalovirus (HCMV) infects more than 80% of the global population. While mostly asymptomatic, HCMV infection can be serious among the immunocompromised, and it is implicated in chronic disease pathology in adulthood. Large-scale minimally-invasive HCMV screening could […]
Methods for highly sensitive measurement of SARS-CoV-2 viral RNA and antibodies from a single saliva sample
Ultrasensitive measurement of both SARS-CoV2 RNA and serology from saliva D Ter-Ovanesyan et al., (2021) medRxiv ABSTRACT: Tests for COVID-19 generally measure SARS-CoV2 viral RNA from nasal swabs or antibodies against the virus from blood. It has been shown, however, that both viral particles and antibodies against those particles are present in saliva, which is […]
Behavior problems in youth may show a higher salivary cortisol – alpha-amylase coordination
The within-person coordination of HPA and ANS activity in stress response: Relation with behavior problems FR Chen et al., (2020) Psychoneuroendocrinology ABSTRACT: This study tests the within-person coordination of HPA and ANS activity in response to stress and examines for the first time the association between such coordination and behavior problems in minority urban children. […]

Utility of routine salivary COVID-19 testing to prevent outbreaks in frontline healthcare workers
Routine saliva testing for the identification of silent COVID-19 infections in healthcare workers Zhang, K et al., (2020) MedRxiv ABSTRACT: Objective: Current COVID-19 guidelines recommend symptom-based screening and regular nasopharyngeal (NP) testing for healthcare personnel in high-risk settings. We sought to estimate case detection percentages with various routine NP and saliva testing frequencies. Design: Simulation […]
Another Salivary Bioscience Breakthrough: Research Study Obtains 100% Sensitivity and Specificity for COVID-19 Serology with Support from Salimetrics
(November 24, 2020) Recently, infectious disease experts at Johns Hopkins and Emory University, in collaboration with Salivary Bioscience experts from Salimetrics and the University of California, Irvine, published a preliminary report in the Journal of Clinical Microbiology for a saliva/oral fluid-based study related to COVID-19 immunology. At a critical juncture during the era of COVID-19, [...]
