RT-PCR is a gold standard method for the diagnosis of the disease used at all over the world. The highest number of sample size (1,461,258 patient sample) and differing results are reported with our study regarding the PCR positivity rates.
Method/Study Design: The study was aimed to evaluate the positivity and negativity of the patients with RT-PCR from all the samples studied between March 25, 2020 and March 25, 2021, when the pandemic was declared and started to be seen in Turkey, and to investigate its contribution to the total test capacity of our country.
Results/Conclusions: 1,461,258 patient is observed, and this frequency male is 58% and female is 42% of the population. The maximum number of admissions is noticed during the Autumn-2020 involved age ranged from 25 to 35. 14.6% positive result is got while the 85.4% negative result is observed. When the age distribution of COVID-19 (+) patients is evaluated, COVID-19 (+) rate is highest in the 6-15 age range, followed by the 66-75 age range and the highest COVID-19 (+) rate are November and October, respectively. Additionally, the highest COVID-19 (+) rate is in Autumn.
