Article Synopsis
- - This study investigates how vaccination status affects RT-PCR cycle threshold (Ct) values in suspected COVID-19 cases, comparing results from rapid diagnostic tests (RDT) and RT-PCR testing.
- - Among 453 suspected cases, RDT showed 65.8% positive and RT-PCR showed 64.2% positive results, indicating discrepancies between the two testing methods.
- - The findings suggest that vaccination status has little influence on viral load as indicated by Ct values, complicating the interpretation of tests for vaccinated individuals, particularly in cases of breakthrough infections.
Background: Fetal calf serum (FCS), an existing cell culture supplement, is effective but has several drawbacks, including being expensive, requiring a lengthy process of production, and requiring a hard currency. With this in mind, we planned to evaluate chick embryo extract and egg yolk extracts in cell culture as alternatives to fetal calf serum (FCS).
Methods: Specific pathogen-free eggs were purchased from the National Veterinary Institute, Bishoftu, Ethiopia, and incubated in a humidified incubator at 37 °C for 11 days.
Background: Serum indices (SI) including hemolyzed, lipemic, and icteric samples, affects the accuracy of test result. The aim of this study was to evaluate SI values done by visual inspections and potential false result risks by comparing with actual measurements done by Cobas 6000 Chemistry analyzer at Ethiopian Public Health Institute (EPHI), Addis Ababa, Ethiopia.
Methods: An observational, cross-sectional study was conducted from April to May 2017 on samples referred to Clinical Chemistry laboratory of EPHI, Ethiopia.
