Antigen Tests
Antigen tests are rapid diagnostic tests that identify viral antigens. They typically provide results within 15-30 minutes. Their speed and relative affordability make them a popular choice for quick results. However, antigen tests might yield false negatives, especially in early stages of infection or when viral load is low.
Molecular Tests
Molecular tests, also known as PCR tests, analyze the genetic material of the virus. They are generally more accurate than antigen tests, particularly in identifying low viral loads. However, they typically take longer to produce results (24-48 hours). The higher accuracy often comes at a higher cost.
Accuracy, Speed, and Cost Comparison
The accuracy, speed, and cost of different home COVID-19 tests vary considerably. This variation is a direct consequence of the different testing methodologies employed.
| Test Type | Accuracy | Speed | Cost | Pros | Cons |
|---|---|---|---|---|---|
| Antigen | Moderately accurate, lower viral loads can yield false negatives. | Fast (15-30 minutes) | Generally lower | Rapid results, convenient | Potentially lower accuracy, false negatives possible |
| Molecular (PCR) | High accuracy, detects low viral loads | Slower (24-48 hours) | Generally higher | High accuracy, reliable detection of low viral loads | Longer turnaround time, higher cost |
Steps in Performing a Home COVID-19 Test
The steps involved in performing a home COVID-19 test are generally straightforward and user-friendly. Following the manufacturer’s instructions precisely is crucial for accurate results.Most home COVID-19 tests involve collecting a sample from the nose or throat, typically by using a swab.

Factors Affecting Home Test Accuracy
Accurate results from home COVID-19 tests depend heavily on adherence to the manufacturer’s instructions. Improper sample collection techniques or incorrect handling of the test kit can lead to inaccurate readings. Furthermore, the time frame within which the test must be conducted, from sample collection to interpretation, is crucial. Exceeding the recommended time can affect the test’s accuracy.
Reasons for False-Positive Results
False-positive results occur when the test indicates a positive result for COVID-19, but the individual is not actually infected. This can arise from several factors. A non-specific reaction of the test to other substances present in the sample can cause a false-positive. Furthermore, environmental contaminants can interfere with the test, leading to a false positive. Finally, improper test storage or handling can also contribute to false-positive results.
Reasons for False-Negative Results
False-negative results occur when the test indicates a negative result, despite the individual being infected with COVID-19. These results can stem from various factors. The viral load, or the amount of the virus in the sample, may be too low for the test to detect. Also, the sample may not be collected correctly or at the appropriate time in the infection cycle, reducing the chances of a positive result.
Another possibility is the presence of interfering substances in the sample that mask the presence of the virus.
