Detection of SARS-CoV-2 by using real-time PCR nasopharyngeal swabs in suspected patients and their clinical medication
Abstract
Background: The corona name derived from their crown like spike proteins attach with cell receptors. It belongs to coronaviradae family and nideovirales order, envelop virus, size range 65–125 nm and positive single standard RNA between 26.4 and 31.7 kb and contain 7096 amino acid. There are four subtypes that have been detected these are alpha, beta, gamma and delta. Methodology: The 267 covid-19 blood and nasopharyngeal samples were collected from Multan region. RNA extraction from nasopharyngeal samples and run the PCR. The blood samples use for clinical tests, Lactate dehydrogenase, serum ferritin level, D-Dimer, TG, cholesterol, thyphoidot, HDL, lymphocyte count and CRP. Results: 127 (47.21%) out of 267 patients were covid-19 PCR positive and showed the amplification of ORF1ab, E, and N gene, while 140 individuals were covid-19 PCR negative and not showed the amplification of ORF1ab, E and N gene. The patients with negative Covid-19 PCR, the other analysis tests such as lactate dehydrogenase, HDL, ferritin, ESR, CBP, D-Dimer, Tg, cholesterol, CRP and CT scan. The patients effected covid-19 have higher values of D-Dimer, ESR, Neutrophils, LDH, CRP and ferritin level than normal ranges. However, the values of HDL, cholesterol and lymphocytes were decreased from the normal range.
