Coronavirus Disease (Covid-19)

Coronavirus Disease 2019 ( Covid 19)

We are offering COVID-19 Diagnostic Test and COVID-19 Antibody Test at all our locations.

COVID-19 Antibody Test: For higher sensitivity and specificity, we are offering a Lab based Serology test which involves a blood draw. We also offer a rapid test onsite. Rapid COVID-19 diagnostic test with the Sofia 2 SARS Antigen Fluorescent Immunoassay (FIA) for qualitative detection of nucleocapsid protein from SARS-CoV-2 using the Sofia 2 analyzer which provides automated and objective results in 15 minutes. This test received FDA EUA approval on May 8th, 2020.

We have curbside/drive-through COVID-19 diagnostics testing. Patients are asked to remain in their cars while our staff meets them in the parking lot to collect nasal swab. As part of Safe Work Practices we are ensuring that our offices are regularly disinfected with special attention to door handles, waiting room furniture, and bathrooms. Our staff is following safety measures and working diligently to maintain a safe environment for our patients Your safety is important to us.

We are offering Covid-19 testing at job-site. Employers in need of "on premises testing", kindly contact us at

About Antibody Testing

Antibody testing is done via a blood specimen. It involves a normal blood draw via venipuncture at our office. Your specimen is then sent to the lab for testing, We are currently sending blood specimen to BioReference
Laboratories for testing who claim the following:
Antibodies are proteins produced by the body’s immune system to try to fight infection. The antibody test offered by BioReference measures IgG. This type of antibody can usually be detected several weeks after an infection starts, and remains elevated for a significant period of time after.

Antibody tests offered by BioReference are performed on high-volume instruments, have been verified for sensitivity and specificity. They have been reviewed by appropriate state Departments of Health, and registered with the FDA.


Testing positive for COVID-19 antibodies provides likely evidence of previous infection with the COVID-19 virus. It may also mean that a patient has immunity to re-infection, based on information about other infections. Studies looking specifically at COVID-19 are ongoing, and will provide more data on how immunity works for this virus.


Antibody results plays a critical role in the fight against COVID-19, by helping healthcare professionals and public health authorities assess the immune response in populations and individuals. Many COVID-19 patients have mild or no symptoms, and may not have been diagnosed when infected. Antibody testing can provide information about who has been infected, and who may potentially be immune from re-infection. Antibody blood testing from BioReference can help healthcare professionals in making decisions about people returning to work, and easing social distancing measures and shelter-in-place measures.

Test Results

Test results can take up to 5 days.
You can review results for your Antibody test by setting up a patient portal account with BioReference.

To get started, please go to:
If you need assistance with setting up the portal please call 1-833-4MYLABS (1-833-469-5227) M-F 8-8 ET or email

For questions pertaining to lab results, call our office to speak with a provider.

Keep your hands clean by washing often with soap and water for at least 20 seconds, especially after visiting a public place, or after blowing your nose, coughing, or sneezing. If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol.

Avoid touching your eyes, nose, and mouth.
Keep safe distance and avoid close contact with people in general
Work from home, if possible and stay home if sick
Cover coughs and sneezes. Wear a mask, if sick.
Clean and disinfect frequently touched surfaces specially doorknobs, light switches, countertops, handles, toilets, faucets, and sinks.

Self Monitoring

Do health checks every morning and every night or anytime you feel like you might have a fever: • Take your temperature and/or that of family members who are being monitored • In addition to fever, be alert for any other symptoms of COVID-19, including cough or shortness of breath. • Write your temperature and any symptoms in the log.

Stay home and separate yourself from other members of your household. Try to restrict yourself to your room and bathroom, if possible.

Do not share toiletries, kitchen utensils, and other personal or household items

Keep your hands clean by washing regularly with soap and warm water.

Be mindful when touching doorknobs, light switches, frequently used surfaces in a shared household. Keep surfaces clean

Avoid non essential visitors in the house

Keep safe distance and wear a mask when you need to be in contact with others. If masks are not available use tissues, paper napkins or paper towel to cover sneezes and cough.

Self Monitor your temperature and overall health condition. Seek timely help if you are experiencing shortness of breath or if symptoms start to worsen. Patients with underlying health conditions may need close medical supervision so speak with the doctor.

Discontinuation of Home Isolation for Persons with COVID-19

Interim Guidance from CDC

The decision to discontinue home isolation should be made in the context of local circumstances. Options now include both 
1) a time-since-illness-onset and time-since-recovery (non-test-based) strategy, and
2) a test-based strategy.

Time-since-illness-onset and time-since-recovery strategy (non-test-based strategy)* Persons with COVID-19 who have symptoms and were directed to care for themselves at home may discontinue home isolation under the  following conditions:
At least 3 days (72 hours) have passed since recovery defined as resolution of fever without the use of fever-reducing medications and improvement in respiratory symptoms (e.g., cough, shortness of breath); and,
At least 7 days have passed since symptoms first appeared. Test-based strategy (simplified from initial protocol) Previous recommendations for a test-based strategy remain applicable; however, a test-based strategy is contingent on the availability of ample testing supplies and laboratory capacity as well as convenient access to testing. For jurisdictions that choose to use a test-based strategy, the recommended protocol has been simplified so that only one swab is needed at every sampling.

Persons who have COVID-19 who have symptoms and were directed to care for themselves at home may discontinue home isolation under the following conditions:
Resolution of fever without the use of fever-reducing medications and Improvement in respiratory symptoms (e.g., cough, shortness of breath) and Negative results of an FDA Emergency Use Authorized molecular assay for COVID-19 from at least two consecutive nasopharyngeal swab specimens collected ≥24 hours apart** (total of two negative specimens). See Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens from Persons Under Investigation (PUIs) for 2019 Novel Coronavirus (2019-nCoV)for specimen collection guidance.
Individuals with laboratory-confirmed COVID-19 who have not had any symptoms may discontinue home isolation when at least 7 days have passed since the date of their first positive COVID-19 diagnostic  test and have had no subsequent illness.

*This recommendation will prevent most, but may not prevent all instances of secondary spread.  The risk of transmission after recovery, is likely very substantially less than that during illness. **All test results should be final before isolation is ended. Testing guidance is based upon limited information and is subject to change as more information becomes available.
