Introduction

Antigen self-test kits have become an essential tool in managing and controlling the spread of infectious diseases, particularly during the COVID-19 pandemic. These kits offer a rapid and convenient method of testing, allowing individuals to perform tests at home without professional assistance. However, questions regarding their accuracy, sensitivity, and specificity remain a concern for many users.

Accuracy of Antigen Self-Test Kits

Antigen self-test kits are designed to detect specific proteins from the virus. The accuracy of these tests is determined by two primary parameters: sensitivity and specificity.

Sensitivity

Sensitivity refers to the test's ability to correctly identify individuals with the disease (true positive rate). A high sensitivity reduces the risk of false negatives. For instance, many antigen tests for COVID-19 report sensitivity ranges between 70% to 85%, meaning that out of 100 infected individuals, 70 to 85 will be correctly identified as positive.

Specificity

Specificity is the test's ability to correctly identify individuals without the disease (true negative rate). High specificity minimizes false positives. Most antigen tests demonstrate specificity rates above 90%, indicating robust performance in identifying uninfected individuals correctly.

The variation in accuracy is influenced by viral load, the timing of the test during the infection course, and the quality of the test kit itself.
