An observational study in Infection, Bacterial and Infection Viral, sponsored by Beckman Coulter, Inc.. Completed at 4 sites in United States. Open to participants aged 90 Days to 89 Years. Per ClinicalTrials.gov, last updated 2025-06-05.
Sponsored by Beckman Coulter, Inc. (part of Danaher Corporation) · Observational
The purpose of the pivotal study is to collect blood specimens and clinical data from pediatric (>90 days old) and adult (≥18 years old) patients presenting with signs and symptoms suggestive of acute bacterial or viral infection. These samples will be used to establish the diagnostic performance of MeMed BV™ for differentiating bacterial from viral infection using method comparison and/or method concordance.
The objective of this study is to collect blood specimens from pediatric (>90 days old) and adult patients (≥18 years old) presenting with signs and symptoms suggestive of acute bacterial or viral infection from hospital, Emergency Department, or Urgent Care Centers for comparative testing on the Access 2 and DxI 9000 Immunoassay Analyzers.
584 studies on the registry are indexed under Bacterial Infections; 84 are open to participants now.
This study's enrollment of 650 is above the median of 200 across 185 observational studies indexed under Bacterial Infections.

Pediatric and adult patients presenting to the Emergency Department or Urgent Care Center with signs and symptoms suggestive of acute bacterial or viral infection.
The study sample size will be divided into the following:
The target population will be representative of US demographics. This sample size aligns with comparator device studies. Pediatric sample collection will be separated into the following three (3) age categories:

The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

A minimum of 244 serum samples will be collected at a minimum of two (2) US locations from enrolled pediatric and adult patients presenting signs and symptoms suggestive of acute bacterial or viral infection. The number of patients enrolled is based on total volume required to run analytical comparison studies under a future testing protocol.
Other: Adult and Pediatrics
This is an observational study. This protocol is for blood draw enrollment. These samples will be collected and binned by their results from the MeMed BV assay. Samples collected will be used for an analytical comparison study under a future testing protocol. These samples will be used to establish the diagnostic performance of MeMed BV test on BEC Access Immunoassay Systems for differentiating bacterial from viral infection.
Blood Specimen Collection
Collect blood specimens across multiple age ranges presenting symptoms of acute or viral infection
Time frame: Less or equal to seven days
