The RT-PCR Nasal Swab For Covid-19, Explained

An in-home Covid-19 nasal swab test is a convenient and accurate way to determine if you have SARS-CoV-2 without the hassle of long lines and testing kit shortages at your local testing center.

What Is A RT-PCR Test?

The RT-PCR Covid-19 nasal swab is a simple test in which a clinician collects a sample from the inside of your nose in order to detect active Covid-19 infection. The sample must be sent to a lab for analysis and processing, and results are generally available within 3 business days.

What’s the difference between the RT-PCR Test and the rapid antigen test?

Although both the RT-PCR test and rapid antigen test are typically administered by nasal swab, they are different tests.

  • The RT-PCR test looks for specific genetic material and must be sent to a lab for processing.
  • The rapid antigen test looks for proteins on the surface of the virus and can be processed onsite within 15 minutes.

How does in-home Covid-19 testing work?

  • One of our nurses comes to your location of choice to administer the test.
  • During your appointment, our nurse will collect a sample from the inside of your nose.
  • They will then send the sample to a lab for processing.
  • You will receive your results and consultation over the phone.

Our service is NOT a DIY kit.

Which methods are used to collect the sample?

The RT-PCR test is administered via a nasal swab.

How accurate is the RT-PCR test?

The RT-PCR test is considered the most accurate of all the Covid-19 tests. Its high accuracy comes down to how the test is designed to work.

The RT-PCR test looks for the virus’s RNA. During processing, the RNA is converted into DNA. This DNA is then amplified enough that the sample can be measured using a fluorescent dye. This dye reacts with the DNA if it’s present, giving the lab technician your answer.

In short…

  • If there is no RNA from the virus present, then no DNA can be amplified, and there will be no fluorescence (the test is negative).
  • If RNA from the virus is present, then the DNA will be amplified, and there will be fluorescence (the test is positive).

Can you get an RT-PCR test at home?

Yes, you can get an RT-PCR test at home. Some laboratories are offering at-home kits that can be mailed directly to you or picked up at select pharmacies. After you have administered the test, you will then need to mail the sample to the lab for standard processing.

Is in-home testing available?

Yes. You can get an in-home RT-PCR test with Drip Hydration. One of our registered nurses comes to you and takes care of administering the test, sending the sample to our lab, and consulting you with your results.

Are there reliable self-testing kits?

The accuracy of self-testing kits is rated by their manufacturer. We recommend that you check on the manufacturer’s website for information about their RT-PCR test accuracy.

How much does it cost to get an RT-PCR test?

It depends on where you get the test. Many community or drive-in testing centers are offering free or low-cost Covid-19 tests. Testing costs vary from state to state. Check with your local testing center to find out how much a test will cost you.

DIY kits may cost $199 or more. An in-home service such as Drip Hydration costs $249, which includes professional medical attention and advice.

What Do Test Sensitivity And Specificity Mean?

Test sensitivity and test specificity refer to the threshold that a particular medical test uses to gauge whether an individual is considered ‘sick’ or ‘healthy’. Tests are designed to have a threshold that is high enough that it correctly identifies sick individuals and low enough to exclude healthy individuals.

  • Test sensitivity is the proportion of sick individuals the test correctly identifies.
  • Test specificity is the proportion of individuals who are not sick that the test correctly identifies.

Reading material:

Tests with high sensitivity are less likely to give incorrect results such as false negatives and false positives. Tests with low sensitivity or specificity are more likely to give incorrect results.

What are false positive and false negative results?

  • False positive: The individual tests positive even though they are not actually sick. False positives sometimes occur if a person has a coronavirus strain other than SARS-CoV-2 (Covid-19).
  • False negative: The individual is sick but the test comes back negative.

Getting a test with high sensitivity and specificity is important to prevent these incorrect results. False positives can lead to additional costs, treatments, and fear. Since you may not seek treatment if you do not think you are sick, a false negative can potentially cause an unintentional spread of the illness or worsening symptoms.

That’s why our PCR nasal swab test has high specificity and sensitivity – we want to provide you with results that are as accurate as possible.
