Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to compare plasma S Protein levels to SARS-CoV-2 viral load in COVID positive patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Non-pharmacological, non-interventional, prospective, monocentric study involving the use of biological materials.

There will be two cohorts:

* COVID + cohort: 50 patients with positive nasopharyngeal swab and / or BAL.
* Control Cohort: 20 patients with non-SARS-CoV-2 related pneumonia.

The study involves analyzing biological samples collected for normal clinical practice.

In particular:

* blood samples will be used for PROS and Sflt1 assay, haematological, biochemical and coagulation tests.
* Samples deriving from nasopharyngeal swab or from Broncho-Alveolar Lavage (BAL) liquid will be used for Real time PCR analysis to evaluate the viral load of SARS CoV-2.
