Analytic comparison between three high-throughput commercial SARS-CoV-2 antibody assays reveals minor discrepancies in a high-incidence population
( Nature Research , 2021 , Article)Performance of three automated commercial serological IgG-based assays was investigated for assessing SARS-CoV-2 "ever" (past or current) infection in a population-based sample in a high exposure setting. PCR and serological ... -
Assessing the performance of a serological point-of-care test in measuring detectable antibodies against SARS-CoV-2
( Public Library of Science , 2022 , Article)This study investigated the performance of a rapid point-of-care antibody test, the BioMedomics COVID-19 IgM/IgG Rapid Test, in comparison with a high-quality, validated, laboratory-based platform, the Roche Elecsys ... -

Coronavirus Disease 2019 Disease Severity in Children Infected With the Omicron Variant
( NLM (Medline) , 2022 , Article)SHORT SUMMARY: Severe acute respiratory syndrome coronavirus 2 infection from the Omicron variant in children/adolescents is less severe than infection from the Delta variant. Those 6 to <18 years also have less severe ... -
COVID-19 Disease Severity in Persons Infected with Omicron BA.1 and BA.2 Sublineages and Association with Vaccination Status
( American Medical Association , 2022 , Article)Infection with the SARS-CoV-2 Omicron variant is associated with less severe disease compared with the Delta variant.1-3 Two main Omicron sublineages—BA.1 and BA.2—have variable geographic distribution. In Qatar, BA.1 was ... -
Dengue and chikungunya seroprevalence among Qatari nationals and immigrants residing in Qatar.
( Public Library of Science , 2019 , Article)The objective of this study is to characterize the seroprevalence of anti-dengue (DENV) and anti-chikungunya (CHIKV) antibodies among blood donors residing in Qatar who are Middle East and North Africa (MENA) nationals and ... -
Diagnostic Efficiency of Three Fully Automated Serology Assays and Their Correlation with a Novel Surrogate Virus Neutralization Test in Symptomatic and Asymptomatic SARS-COV-2 Individuals
( MDPI , 2020 , Article)Abstract: To support the deployment of serology assays for population screening during the COVID-19 pandemic, we compared the performance of three fully automated SARS-CoV-2 IgG assays: Mindray CL-900i® (target: spike [S] ... -
Effect of multiple freeze–thaw cycles on the detection of anti-SARS- CoV- 2 IgG antibodies
( Microbiology Society , 2021 , Article)Several studies have investigated the effect of repeated freeze-thaw (F/T) cycles on RNA detection for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). However, no data are available regarding the effect of ... -
Estimating Seroprevalence of Herpes Simplex Virus Type 1 among Different Middle East and North African Male Populations Residing in Qatar
( Wiley , 2017 , Article)HSV-1 epidemiology in the Middle East and North Africa (MENA) remains poorly understood. Our study aimed to measure HSV-1 antibody prevalence (seroprevalence) and its age-distribution among select MENA populations residing ... -
Herpes Simplex Virus Type 2 Seroprevalence Among Different National Populations of Middle East and North African Men
( Lippincott, Williams & Wilkins , 2018 , Article)BACKGROUND: There are limited data on herpes simplex virus type 2 (HSV-2) seroprevalence in the Middle East and North Africa (MENA). We examined country- and age-specific HSV-2 seroprevalence among select MENA populations ... -
