Background: Rotaviruses are the major cause of severe dehydrating diarrhea in children throughout the world. Enzyme immunoassays (EIAs) have been the standard method for detection of rotavirus in stool specimens since the 1980s. The World Health Organization (WHO) Rotavirus Surveillance Network has proposed including three EIA kits in the WHO-GSM (Global Management System/Système Mondial de Gestion) catalog for easy procurement of EIA kits by participating rotavirus surveillance network laboratories.
Objectives: In this study, we conducted a comparative analysis of 3 commercially available enzyme immunoassay kits: Premier™ Rotaclone® (Meridian Bioscience, Inc.), ProSpecT™ (Oxoid, Ltd.) and RIDASCREEN® (R-biopharm AG) for rotavirus diagnostics.
Study Design: Using reverse-transcriptase-PCR (RT-PCR) as the gold standard, the 3 EIA kits were evaluated by testing a stool panel consisting of 56 rotavirus-positive and 54 rotavirus negative samples.
Results: The sensitivities of the Premier™ Rotaclone®, ProSpecT™ and RIDASCREEN® kits were 76.8%, 75% and 82.1%, respectively, but did not differ significantly. The specificity of all the 3 kits was 100%. The use of RT-PCR as a gold standard lowered the observed sensitivity of all 3 EIA kits but helps to reduce equivocal results that can be seen when another EIA or other non-molecular methods are used as the reference assay in comparison studies.
Conclusion: Our study found that all three kits are suitable for use by rotavirus surveillance programs.

Advancing knowledge of endocannabinoid receptor agonists and the federal legalization of hemp has created a cannabinoid market of naturally abundant phytocannabinoids to a wide array of semi-synthetic and synthetic cannabinoid analogs. Public safety and toxicological concerns exist from lack of regulation, limited pharmacological and metabolomic data, and minimal knowledge of detection ability. Structural similarities of the cannabinoid analogs may allow detection on immunoassays including enzyme-linked immunosorbent assays (ELISA) and homogenous enzyme immunoassays (HEIA), screening platforms in forensic toxicology laboratories for rapid presumptive testing.

Background & objectives This study was performed to assess the suitability of dried blood spot (DBS) samples for the serological screening of syphilis. Methods Two hundred paired DBS and plasma samples collected from six sexually transmitted infection (STI) clinics during the year 2023 were tested using three kits -Treponema pallidum haemagglutination assay (TPHA), Syphilis Total Ab and ErbaLisa Syphilis after standardization of the dilutions of the DBS elutes and considering the results of the paired plasma samples as a true status. Results The TPHA showed 89 per cent sensitivity and 100 per cent specificity, the EIA-Syphilis Total Ab.

Blood serum (BS) and seminal plasma (SP) share a plethora of compounds that might present an individual and/or temporal concentration variation. We aimed to determine whether BS and SP concentrations of albumin, calcium, citrate, creatinine, fructose, glucose, lactate, total protein, urea, zinc, cortisol, anti-Müllerian hormone (AMH) and testosterone are related to weekly collections in New Zealand White (NZW) adult rabbit bucks. During a 12-week study, blood samples were obtained at the beginning and the end of the study period, and semen samples were taken twice a week from four NZW adult rabbit bucks, starting at 6-7 months of age.

Introduction: We evaluated the application of a newly improved enzyme immunoassay (EIA) kit, Mumps IgG Seiken®, by comparing antibody responses to different EIA kits, and neutralization tests (NTs), using clinical samples.
Methods: Serum samples were collected before and 4-6 weeks after vaccination from 128 children who had no history of mumps or mumps vaccination. Using three different EIA kits, Mumps IgG Seiken®, a commercial kit from Enzygnost®, and an in-house kit, mumps-specific IgG antibodies were measured.
