Introduction

The COVID-19 pandemic has necessitated the widespread use of self-test kits, largely due to their convenience, rapid results, and accessibility. Understanding their accuracy is essential for proper public health management and individual decision-making. This article examines the accuracy of these tests based on sensitivity, specificity, and other performance metrics.

Accuracy of COVID-19 Self-Test Kits

Sensitivity

Sensitivity refers to a test's ability to correctly identify those with the disease (true positive rate). For COVID-19 self-test kits, sensitivity ranges widely from 85% to 98% depending on the brand. High sensitivity is crucial to minimize false negatives, ensuring infected individuals are not overlooked.

Specificity

Specificity indicates a test's ability to correctly identify those without the disease (true negative rate). COVID-19 self-test kits generally exhibit specificity between 95% to 99%. High specificity reduces false positives, thus important for preventing unnecessary anxiety and isolation.

Immuno Company Solutions

Immuno Company provides several COVID-19 diagnostic solutions, focusing on enhancing accuracy.

• Rapid Antigen Tests: Featuring a sensitivity of 90% and specificity of 98%, these tests offer a balance of quick results and accuracy.
• PCR Tests: Gold-standard with 99% sensitivity and specificity, but typically require laboratory processing.
• Home Antibody Tests: Provide insights into past infection with a specificity of 95% and sensitivity of 90%.
