COVID-19 Testing at Emerson Hospital

Emerson Hospital is pleased to offer quick access to convenient testing for our community! Test sites include Emerson's urgent care locations and our drive-through test site located in the parking lot of 200 Baker Avenue in Concord.

Getting Tested

COVID-19 testing with a doctor’s order is covered by insurance, and there is no out-of-pocket expense. If you do not have a doctor’s order and wish to get tested, you may self-pay for your COVID-19 test at our drive-through location at 200 Baker Ave. in Concord.

  • Self-pay tests are scheduled through our online scheduling portal. The cost to self-pay is $105. Click here to schedule.

All tests billed to an insurance company require a doctor’s or nurse practitioner’s order. These tests can be conducted at our urgent care centers in Hudson and Littleton as well as our drive-through location in Concord. Call your primary care doctor (PCP) to obtain an order. Once we receive your order, Emerson central COVID scheduling will call you to schedule a test.

  • If you have symptoms or were exposed to COVID-19, you will be called within 24 hours or the next business day. If you have no symptoms, you will receive a call within 72 hours.
  • If you need to be tested in preparation for a surgery or procedure, you will be called within 48 hours of receiving your order.
  • If you do not get a call from our scheduling team within these time frames, call central COVID scheduling at 978-371-2684 (978-371-COVI).

If you are feeling symptomatic and do not have a PCP, call Emerson Urgent Care directly to schedule a test at 978-287-8990.

WHAT TYPE OF COVID-19 TEST DOES EMERSON PERFORM?

Viral tests, also referred to as PCR tests, are used to diagnose COVID-19. At the Emerson laboratory we have three different PCR test systems in use. Test are collected by a nasal swab and the results are usually back within two days. Because demand is so high, we also send tests to the Broad Institute of Harvard/MIT, and we strive to get the results back within approximately 72 hours.

If your test is positive, it is more than 99 percent accurate in diagnosing a COVID-19 infection. However, up to 30 percent of people who have COVID-19 will test negative by the viral test. The test is less likely to be positive the longer it has been since the start of your symptoms. The viral test becomes negative over time so it is not used to show if you have had a past infection.

Emerson also has the capacity to perform COVID-19 total antibody tests. Speak with your provider if you feel you may be a candidate for this test, as they must order it.

ANTIBODY TESTING

Antibody testing, also referred to as serology testing, checks a sample of a person’s blood to determine if your body has produced proteins that fight COVID-19. It typically takes between one and three weeks to develop these proteins, known as antibodies. Some people may take even longer to develop antibodies and some people may not develop antibodies. Antibody tests are generally not used to diagnose acute COVID-19. PCR (viral) tests are used to diagnose COVID-19.

A positive antibody test may mean that you may have been infected with the COVID-19 virus. The antibody test has a significant rate of false positives (people getting a positive antibody test who were not actually infected). A positive test does not mean that you are immune to COVID-19. It is not known yet if having antibodies to COVID-19 can protect you from getting infected again. Even if they do protect you, it is unknown how long that protection will last.

Antibody testing can be offered as a method to support the diagnosis of COVID-19 illness for those who present late (and who therefore may have a false-negative COVID-19 PCR test result).

The Massachusetts Department of Health does not recommend antibody testing at this time. Antibody tests are not indicated for diagnostic purposes. In order to be appropriately interpreted, more data is needed on the performance characteristics of these tests, the immune response to COVID-19, the timing and duration of antibody response, and how antibodies correlate to protective immunity.

KEY POINTS ABOUT THE USE OF SEROLOGIC/ANTIBODY TEST RESULTS

Serologic tests should:

  • NOT be used to determine a person’s immunity to COVID-19
  • NOT be used to make decisions about relaxing or not following social distancing guidelines
  • NOT change the use of personal protective equipment (PPE) by health care workers and first responders
  • NOT be used to make decisions about returning persons to the workplace
