NCT04756518

Brief Summary

COVID-19 infection is currently confirmed by a complex, multiple-step procedure starting with a mucosal swab, followed by viral RNA extraction and processing and qPCR. This study aims to explore a novel method using machine learning and artificial intelligence (AI) algorithm to diagnose COVID-19 infection through the morphological analysis of lymphocyte subset in the peripheral blood. This study will also risk stratify patients with COVID 19 infection based on the above finding along with other clinical, haematological and biochemical parameters with a view to predict clinical outcome with high sensitivity and specificity.

Outcome Measures

Primary Outcomes (1)

  • Diagnosis of COVID-19.

    Determine whether lymphocytes alone can diagnose COVID-19 disease with high specificity and sensitivity, using AI-based image analytical modelling.

    6 months

Secondary Outcomes (1)

  • Severity of COVID-19 infection modelling

    6 months

Study Arms (2)

COVID 19 group

The COVID 19 group will consist of peripheral blood smear slides from patients who are in the hospital who had qPCR results positive for COVID-19.

CONTROL group

A control group will consist of i) peripheral blood smear slides from patients with no viral infection and ii) from those with a non-SARS-CoV-2 viral infection. Control group peripheral blood slides will be randomly selected from the laboratory slides archive within the facility. The laboratory slides used will be inclusive of slides archived prior to the emergence of COVID-19 infection in the United Kingdom.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Peripheral blood smears obtained from adult non-SARS-CoV-2 positive patients and from adult positive SARS-CoV-2 patients.

You may qualify if:

  • Female or male participants
  • Aged over 18 years old (no upper age limit)
  • Patients with SARS-COV-2 positive diagnosis based on qPCR (Study COVID 19 group)
  • Peripheral blood smear slides from patients with no viral infection, reposited in the laboratory slides archive within the facility prior to the emergence of COVID-19 infection in the United Kingdom (Control group)
  • Peripheral blood smear slides from patients with a non-SARS-CoV-2 viral infection that were reposited in the laboratory slides archive within the facility prior to the emergence of COVID-19 infection in the United Kingdom (Control group).

You may not qualify if:

  • Patients that are less than 18 years old
  • Patients with SARS-COV-2 negative diagnosis based on qPCRPatients who have been haematological malignancies with lymphocytosis as predominant manifestation.
  • Patients who have lymphopenia in the past due to underlying inflammatory disorders.
  • Patients who have lymphopenia due to previous cytotoxic or immunosuppressive therapy.
  • Positive diagnosis of Human Immunodeficiency Virus (HIV).
