COVID-19 Quantitative Antibody & PCR FAQ’s

What do I do if my COVID-19 PCR result is positive?2021-01-06T13:13:19-05:00

If you test positive, the CDC guidelines recommends the following:

Stay home unless you need medical care
  • Don’t go to school, work, or any other public areas.
  • Avoid using taxis, ride sharing, or public transportation.
If you do need to visit your doctor, call ahead
  • When you call your doctor’s office, let them know that you tested positive for COVID-19. They will then be able to plan accordingly to limit or eliminate risk to staff or other patients while coordinating any care you may need.
Stay away from other people, pets, or animals in your home
  • It’s important to try as much as possible to stay in a different room and use a separate bathroom (if available) than the other people in your home.
  • Have another member of your household tend to your pets or animals while you are sick. If you live alone or do not have someone else to help with their care, be sure to wash your hands before and after you interact with pets and wear a face mask.
Wear a face mask if you are sick
  • Wear a face mask when you are around other people or pets and before you enter a doctor’s office or hospital.
Cover your coughs and sneezes
  • Cover your mouth and nose with a tissue when you cough or sneeze and throw used tissues in a lined trash can.
  • Immediately wash your hands with soap and water for at least 20 seconds after you sneeze. If soap and water are not available, clean your hands with an alcohol-based hand sanitizer that contains at least 60% alcohol.
Don’t share personal household items
  • Do not share dishes, drinking glasses, cups, eating utensils, towels, or bedding with other people or pets in your home.
  • After using these items, they should be washed thoroughly with soap and water.
Clean all “high-touch” surfaces every day

High touch surfaces include counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets, and bedside tables.

  • Clean and disinfect areas that may have any bodily fluids on them.
Monitor your symptoms
  • Monitor yourself for fever by taking your temperature twice a day and remain alert for cough or difficulty breathing.
    • If you have not had symptoms and you begin to feel feverish or develop measured fever, cough, or difficulty breathing, immediately limit contact with others if you have not already done so. Call your doctor or local health department to determine whether you need a medical evaluation.
  • Seek prompt medical attention if your illness is worsening, for example if you have difficulty breathing. Before going to a doctor’s office or hospital, call your doctor and tell them that you have, or are being evaluated for, COVID-19.
  • Put on a face mask before you enter a healthcare facility or any time you may come into contact with others.
  • If you have a medical emergency and need to call 911, notify the dispatch personnel that you have or are being evaluated for COVID-19. If possible, put on a face mask before emergency medical services arrive.


Why should I get a COVID-19 PCR test as opposed to a Home Test or Antigen Test?2021-01-06T18:09:57-05:00
Home Test

The Coronavirus home test uses a technique called loop-mediated isothermal amplification (LAMP). The method is similar to PCR, the gold standard of COVID-19 diagnostic testing. The LAMP test provides much faster results, but it is less accurate.

Antigen Test

Antigen tests detect specific proteins on the surface of the coronavirus. They are similar to rapid flu or strep diagnostic tests and also take less than an hour for results. Positive antigen test results are highly specific, meaning that if you test positive you are very likely to be infected. However, there is a higher chance of false negatives. Usually, when antigen tests return with a negative result, a COVID-19 PCR result is attained to confirm the result.

PCR Test

PCR tests detect the presence of the virus’s genetic material using a technique called reverse transcriptase polymerase chain reaction, or RT-PCR. Preferably, a deep nasal swab sample is used and then processed. If the coronavirus RNA is present, it is extracted from the sample and converted into DNA. The DNA is then amplified producing a measurable result. PCR tests are highly accurate, but many times can take a week or more for results. At our South Florida laboratory in Boca Raton, our COVID-19 PCR results are rapid and available within minutes while the patient waits. For our medical partners, clinics, and urgent care centers, results are often available as soon as within 24 hours.

Why do we use ABBOTT’s ID NOW for Rapid COVID-19 PCR Results?2021-01-06T13:10:13-05:00

ID NOW utilizes isothermal technology, a proven next-generation molecular technology that uses proprietary enzymes and constant temperature, to achieve the fastest available nucleic acid amplification. The reagents recognize certain sections of the viruses genome and analyzes the target’s RNA makeup.

RdRp Gene

A High-quality molecular technology targeting COVID 19 RdRp gene. There is no long drawn out, off-site laboratory processing required. Results are available within minutes, while the client waits. Likewise, high-volume sample processing from our medical partners deliver rapid results via an online portal within 48 hours.

Sensitivity & Specificity Ratings

Data show ID NOW has a performance of 95.0% sensitivity and 97.9% specificity within seven days of symptom onset. It is also efficacious in detecting mutant strains of the COVID-19 virus, such as the new, highly contagious South African & U.K. strains of the virus, through RNA and genome sequencing.

For more information about the Abbott ID NOW system, contact us to speak to one our team members or visit Abbott ID NOW.

Why do we use Ortho Clinical’s VITROS ECiQ for Rapid COVID-19 Antibody Results?2021-01-06T13:11:21-05:00

The VITROS® ECiQ detects antibodies (including IgG, IgM, and IgA) to SARS-CoV-2 that can be used to detect immune response to the virus. When used in conjunction with molecular tests, this assay is helpful in suspected COVID-19 cases. Additionally, it is used before receiving the vaccine to determine if antibodies to COVID-19 are already present, due to previous infection or exposure. The ECiQ Immunodiagnostic System can also process approximately 150 tests in an hour.

For more information, contact us and a Team Member will provide more information or visit Ortho Clinical.

Type of COVID-19 Tests

What are the different types of COVID-19 Tests?

COVID-19 PCR & Quantitative Antibody Tests vs Antigen Test

There are two different types of tests for COVID-19 – diagnostic tests and antibody tests.


COVID-19 Antigen & COVID-19 PCR. We use Abbott ID NOW COVID-19 PCR Test Results.

Antibody Test

We use Ortho Clinical Vitros ECiQ COVID-19 Quantitative Antibody Test Results.

COVID-19 Antigen vs COVID-19 PCR Results

Which is more reliable: COVID-19 PCR Result or COVID-19 Antigen Result?

COVID-19 Antigen vs COVID-19 PCR Results

A molecular test, like Abbott’s ID NOW COVID-19 PCR test, using a deep nasal swab, is the best option for improved detection because it has fewer false negative results than other diagnostic tests, like antigen tests.

Positive COVID-19 Quantitative Antibody Result

What does a positive COVID-19 Quantitative Antibody result mean?

Positive COVID-19 Quantitative Antibody Result

A positive Covid-19 quantitative antibody result usually means you’ve been exposed to or infected with SARS-CoV-2, the virus that causes COVID-19, within 1 to 3 weeks in the past (which is how long it takes antibodies to develop). It can also mean that you’ve received a vaccine for COVID-19. The quantitative antibody test will also indicate the levels of antibodies to Sars-Cov-2 (COVID-19). This is important as when those antibodies fall below a certain level, you will no longer have the protection from being infected with COVID-19.

Negative COVID-19 PCR Result

If I test negative on the COVID-19 PCR result, when do I retest?

Negative COVID-19 PCR Result

COVID-19’s incubation period can last up to 14 days. If you have the virus, it takes time to build up in your system. Testing too close to an exposure could result in a negative COVID-19 PCR result.

Therefore, we recommend re-testing within 7 to 10 days later.
