Covid-19 infection occurs due to an RNA virus which is single-stranded, called SARS-CoV-2; this virus is similar to SARS-CoV. This review throws light on the available laboratory techniques used for testing coronavirus. Certain challenges are encountered during the development of a diagnostic test for a novel pathogen, which depends on sensitivity of the method, that is, the potential in detecting very low pathogen level for early laboratory diagnosis, produce little or no interference with other strains of the virus, and produce results rapidly. Since the time of incubation and clinical manifestation of the infection are relatively the same with SARS, the widespread and effect of COVID-19 globally serve as the basis why the development of quick and reliable laboratory methods are necessary. Samples that could be collected for covid-19 testing includes blood (especially for screening purpose), nasal and throat swab. Currently, the gold standard method for laboratory diagnosis of Covid-19 infection is RT-PCR, which serves as a confirmatory method for Covid-19 testing. EIA and SVN laboratory techniques are other techniques used in detecting the viral infection. In addition, Rapid Diagnostic Testing (RDT) are currently developed for point-of-care testing, and often used as a screening method of Covid-19 infections. Early detection of the virus remains the primary focus for the treatment and control of SARS-CoV-2 infections. Therefore, this review was aimed at the available laboratory methods used in the diagnosis for coronavirus infection.</p> Jonathan Nyebuchi Emeji, Roseline Konne Felix Eedee ##submission.copyrightStatement## 2021-09-27 2021-09-27 1 7 10.9734/ibrr/2021/v13i130160 Effect of Haemoglobin Variants on Glycemic Indices https://www.journalibrr.com/index.php/IBRR/article/view/30161 <p>Haemoglobin genotypes have been known to be linked with groups of diseases such as diabetes. The aim of this study is to assess the impact of haemoglobin variants on glycemic indices (fasting blood glucose and glycated haemoglobin) in subjects in Bayelsa State, Nigeria. A total of 150subjects were enrolled for the study with AA group = 99 subjects and AS group = 51 subjects. 4mls of blood was collected into EDTA bottle for each subject and was assayed for Hb electrophoresis and glycated haemoglobin (HbA1C) using electrophoretic method and automated CLOVER A1c Analyser respectively. 2mls was collected into fluoride oxalate bottle for spectrophotometric analysis of fasting blood glucose (FBG). Results revealed that there were no significant differences in the FBG and HbA1C&nbsp; mean&nbsp; levels of the two studied groups (AA and AS). This study has shown that AA and AS blood genotypes may not have any impact on FBG and HbA1C glycemic parameters.</p> Victor Tuanwii Jonathan Nyebuchi Albert Lesere Nwibani Friday Ogidigba Felix Eedee Konne Fyneface Chikadibia Amadi ##submission.copyrightStatement## 2021-10-12 2021-10-12 8 12 10.9734/ibrr/2021/v13i130161
