At Home COVID-19 Tests: Know Your Options!

The ongoing COVID-19 pandemic has made testing an essential tool in controlling the spread of the virus. As the access to testing has expanded, over-the-counter (OTC) at-home COVID-19 tests have become a convenient and accessible option for many individuals. In this blog post, we'll explore the different types of OTC COVID-19 tests, discuss their accuracy, and provide guidance on choosing the proper test for your needs.

Types of OTC At-Home COVID-19 Tests

Two main types of OTC COVID-19 tests are available for at-home use: antigen tests and molecular tests. Each test has its unique features and benefits.

Antigen Tests

Antigen tests, also known as rapid tests, detect specific proteins on the surface of the coronavirus. These tests provide quick results, typically within 15-30 minutes, making them an attractive option for those seeking immediate answers.

Pros and Cons of Antigen Tests


  • Fast results
  • Generally more affordable than molecular tests
  • Easy to use


  • Lower sensitivity compared to molecular tests, leading to a higher chance of false-negative results
  • May not be as accurate in detecting asymptomatic cases

Popular Antigen Test Options

  • Abbott BinaxNOW COVID-19 Ag Card
  • Quidel QuickVue At-Home OTC COVID-19 Test
  • Roche Diagnostics SARS-CoV-2 Rapid Antigen Test

Molecular Tests

Molecular tests, which include PCR and isothermal nucleic acid amplification tests, identify the virus's genetic material. While these tests generally take longer to process than antigen tests, they offer higher accuracy.

Pros and Cons of Molecular Tests


  • High sensitivity and specificity, leading to more accurate results
  • Can detect the virus in asymptomatic individuals


  • Results take typically 30 minutes to an hour
  • Tend to be more expensive than antigen tests

Popular Molecular Test Options

  • Lucira COVID-19 All-In-One Test Kit
  • Ellume COVID-19 Home Test
  • Cue Health COVID-19 Test

Accuracy of At-Home COVID-19 Tests

The accuracy of at-home COVID-19 tests varies depending on the type of test and the user's ability to follow the test instructions correctly. Molecular tests, like PCR tests, are considered the gold standard for detecting COVID-19 and have higher accuracy rates than antigen tests.

However, no test is 100% accurate, and false negatives or positives can occur. Suppose you receive an unexpected result or suspect you may have been exposed to the virus. In that case, consulting with a healthcare professional for guidance is essential.

Choosing the Right Test for Your Needs

When selecting an OTC at-home COVID-19 test, consider the following factors:

  1. Purpose: Are you testing due to symptoms, exposure to a confirmed case, or as a precaution before an event or travel? Molecular tests may be more appropriate for asymptomatic individuals or those requiring more accurate results.
  2. Timing: Do you need results quickly? Both antigen and molecular options available OTC can get you timely results from the comfort of your home.
  3. Cost: While prices vary, antigen tests are generally more affordable than molecular tests.
  4. Availability: Check your local pharmacy or online retailers for test availability, as some tests may be more readily accessible than others.


Over-the-counter at-home COVID-19 tests provide a convenient and accessible way to monitor your health and help control the spread of the virus. By understanding the differences between antigen and molecular tests, you can make an informed
