Evaluating the Analytical Equivalency of Serum and Whole Blood Samples Run on the MeMed Key® Platform (Perseverance Study)

Study Overview
=================
Brief Summary
-----------------
This is a Prospective, multi-center, sample collection study enrolling pediatric and adult subjects presented to the ED/Urgent care, with symptoms consistent with acute bacterial or viral infection will be recruited according to eligibility criteria. The study is designed to measure the MeMed BV®️ score in whole blood and serum samples and demonstrate the equivalence between the two matrices. Patients will be managed according to the current standard of care per standard institutional procedures.
