The laboratory's role in combating COVID-19

Area of Science:

• Clinical diagnostics
• Infectious disease epidemiology
• Biochemistry

Background:

• The Coronavirus Disease 2019 (COVID-19) pandemic, caused by SARS-CoV-2, necessitates rapid and accurate diagnostic strategies.
• Laboratory testing, including nucleic acid amplification and serological assays, is crucial for COVID-19 diagnosis and management.
• Biochemical monitoring of blood parameters, cardiac markers, and inflammatory responses aids in assessing disease severity.

Purpose of the Study:

• To review the critical role of clinical laboratories in diagnosing and managing COVID-19.
• To highlight the challenges faced by laboratories in handling the overwhelming number of cases and asymptomatic infections.
• To discuss the need for effective strategies to monitor disease progression and stratify patients.

Main Methods:

• Review of current laboratory diagnostic technologies for SARS-CoV-2.
• Analysis of biochemical and hematological markers used in COVID-19 patient care.
• Discussion of challenges in rapid and accurate patient identification and disease monitoring.

Main Results:

• Nucleic acid amplification tests (NAATs) and serological tests are vital for COVID-19 diagnosis.
• Biochemical tests provide critical information on organ function and inflammatory status.
• Laboratories face significant challenges in scaling up testing and managing patient data.

Conclusions:

• Clinical laboratories play an indispensable role in the global response to COVID-19.
• Advanced diagnostic and monitoring strategies are essential to overcome current laboratory challenges.
• Effective laboratory approaches are crucial for preventing disease exacerbation and improving patient outcomes.
