Platelet Count, Platelet, Mean Platelet Volume and Platelet Distribution Width in COVID-19
Platelet Count, Platelet, Mean Platelet Volume and Platelet Distribution Width in COVID-19
The study will aim to investigate the relation of platelet count (PLT), mean platelet volume
 (MPV) and platelet distribution width (PDW) with other acute phase reactant c-reactive
 protein(CRP) in Coronavirus(COVID-19).

 As a methodology, patients will be selected in records in one month from the online hospital
 system. Two groups will be divided before as need for mechanical ventilation or not. The
 latter comparison will be about three groups as an ambulatory follow-up, hospital follow-up,
 and intensive care unit follow-up. Parameters will be analyzed according to the groups.
In this study, as a methodology, patients diagnosed with PCR test through the online system
 created for COVID-19 patients will be included in the study. These patients will be divided
 into 3 groups as outpatient follow-up, hospital follow-up and follow-up with a mechanical
 ventilator in intensive care. In addition, patients who have completed the 14-day treatment
 period, which is considered as the turning point time of the world health organization by
 looking at the patients 3 times, every 5-7 days, which is the accepted incubation period,
 will be included in the study. In these patients, hemoglobin, leukocyte, platelet, MPV, PDW
 and CRP values will be examined for 3 weekly measurements. Changes in COVID-19 disease
 follow-up and treatment of MPV and PDW values, which have not been studied so far, will be
 investigated.
Inclusion Criteria:

 -  Patients diagnosed with COVID-19, both PCR tests and computed tomography, as well as
 control hemogram and CRP tests at one week intervals will be included.

 Exclusion Criteria:

 -  Those with suspicion of COVID-19, those who do not perform hemogram and c-reactive
 protein tests 3 times with one week intervals, those who do not have standard drug
 treatment will be excluded from the study.
