MeMed COVID-19 Severity
3 Biomarkers + Machine Learning = MeMed COVID-19 Severity
A finalist for AACC’s 2021 Disruptive Technology Award, the MeMed COVID-19 Severity™ test builds on an extensive body of evidence supporting the role of viral-induced TRAIL and IP-10 and inflammatory CRP proteins in severe SARS-CoV-2 infection.1-3*
From a small serum sample, MeMed COVID-19 Severity computationally integrates the levels of these three host immune proteins into a simple score indicating the likelihood of patient deterioration.
To escalate or not to escalate level of care?
Some infections resolve quickly, others lead to severe immune dysregulation, respiratory failure and death. Distinguishing between the two is challenging.
Patients experience life threatening disease4
Under-admission5
Over admission6
Average cost per non-ICU patient7
Conventional tests are important, but insufficient to aid in effective patient management
Uncertainty regarding results interpretation
Fail to alert prior to organ damage
Prolonged turnaround time
Inaccurate risk stratification
Unable to capture disease complexity
Interpreting results
0 ≤ score ≤ 20
Very low
likelihood of severe outcome
20 < score < 40
Low
likelihood of severe outcome
40 ≤ score ≤ 80
Moderate
likelihood of severe outcome
80 < score < 100
High
likelihood of severe outcome
MeMed COVID-19 Severity: Predictive & Actionable
Predictive
- Early indication of deterioration
- Predictive of further disease progression vs. recovery
Actionable
- Ease of use: single serum sample per test
- 15 minutes from sample to result
- Easy to interpret results
Sensitivity*
* applying a score of 40 cutoff
Negative Predictive Value (NPV)*
* applying a score of 40 cutoff
Specificity**
** applying a score of 80 cutoff
Results reference: Independent validation study results, data not published yet.
