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 â€‹nm and positive single standard RNA between 26.4 and 31.7 â€‹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.
