Frequently Asked Questions (FAQs)

PWNHealth is an independent licensed physician network that provides physician services to you in connection with Enzo Clinical Labs. PWNHealth services include clinical oversight of laboratory testing, including physician evaluation of test requests, ordering tests (if appropriate), consults, education sessions, review of test results, and administrative services. These services are independent from the lab testing centers and from Enzo Clinical Labs.

Enzo is working with PWNHealth LLC and its affiliated professional entities (collectively, PWN) to provide independent physician services to you in connection with GoTestMeNow™. PWN services include physician oversight of all tests based upon the information that you share and evaluating results once available. If one or more of your results indicates that you need prompt attention, or is a positive sexually transmitted disease (STD) or HIV result, you will receive a call directly from the PWN team. All of your results will be available on your GoTestMeNow™ account. You will see the amount of fees Enzo is collecting from you on behalf of PWN for their services to you.

PWNHealth provides clinical oversight and care coordination (including independent physician review of test orders) for lab testing programs nationwide. PWNHealth physicians use technology-assisted protocols to facilitate triage, evaluation, patient education and post-test telehealth consults to ensure patients proceed along the appropriate care pathway in a clinically sound manner.

No. PWNHealth is not a reseller or direct distributor of lab testing.

Many states require both laboratory and provider to report positive tests. Enzo and PWNHealth are required by law to report any positive COVID-19 and sexually transmitted diseases, such as chlamydia, gonorrhea, HIV, hepatitis, or syphilis to state or local health departments. You may be contacted to discuss who you’ve been in close contact with. It may be helpful to start thinking of the people you were in close contact with before your symptoms started (or if no symptoms, 2 days before you had your test taken). If you have additional questions, please contact your local health department or visit the CDC website.

COVID-19 General

Regardless of symptoms or vaccination status, you should isolate from others if you test positive for COVID-19.

Stay home for at least 5 days and isolate from others in your home. You are likely most infectious during these first 5 days.

During isolation, you should:

  • Wear a high-quality mask if you must be around others at home and in public.
  • Do not go places where you are unable to wear a mask, including travel and public transportation settings.
  • Stay home and separate from others as much as possible.
  • Use a separate bathroom, if possible.
  • Take steps to improve ventilation at home, if possible.
  • Don’t share personal household items, like cups, towels, and utensils.
  • Monitor your symptoms. If you have an emergency warning sign (like trouble breathing), seek emergency medical care immediately.

Learn more about what to do if you have COVID-19.

If you were in close contact with someone who tested positive for COVID-19, you should start taking precautions regardless of your vaccination status.

  1. Wear a mask as soon as you find out you were exposed
    1. Start counting from Day 1
      1. Day 0 is the day of your last exposure to someone with COVID-19
      2. Day 1 is the first full day after your last exposure
  2. Wear a high-quality mask or respiratory (N95) any time around others, including inside of your home
    1. Avoid places where you are unable to wear a mask
  3. Monitor your symptoms for symptoms of COVID-19:
    1. Fever (100.4°F or greater)
    2. Cough
    3. Shortness of breath
    4. Other COVID-19 symptoms
  4. If you develop symptoms:
    1. Isolate immediately
    2. Get tested
      1. If you test positive, follow isolation procedures
    3. Stay home until you know your test result
  5. On day 6, take a COVID-19 test
    1. Get tested at least 5 full days after your last exposure
    2. Test even if you don’t have symptoms
      1. If you test positive, follow isolation procedures
      2. If you test negative, continue to wear a high-quality mask when around others at home and indoors in public until day 10

You can still develop COVID-19 up to 10 days after you have been exposed.

For additional questions about what to do when you are exposed, visit CDC or contact your healthcare provider.

If you tested positive for COVID-19 and had symptoms, you should isolate for at least 5 days. To calculate your 5-day isolation period, day 0 is your first day of symptoms. Day 1 is the first full day after your symptoms developed.

You can leave isolation after 5 full days without a test if:

  • You are fever-free for 24 hours (without the use of fever-reducing medication)
  • Your symptoms are improving

If you tested positive for COVID-19 and did not have symptoms, you should isolate for at least 5 days. To calculate your 5-day isolation period, day 0 is the day you test. Day 1 is the first full day following the day you were tested.

  • You can leave isolation after 5 full days without a test.
  • If you develop symptoms within 10 days of when you were tested, the clock restarts at day 0 on the day of symptom onset.

If you still have fever or your other symptoms have not improved, continue to isolate until they improve.

If you had?moderate illness? (shortness of breath or difficulty breathing), severe illness?(hospitalization), or have a weakened immune system, you need to isolate through day 10.

If you had?severe illness?or have a weakened immune system, consult your doctor before ending isolation to see if you may need to have a viral test first.

If you are unsure if your symptoms are moderate or severe or if you have a weakened immune system, talk to a healthcare provider for further guidance.

Removing your mask:

Regardless of when you end isolation, wear a high-quality, well-fitting mask when you are around others through day 10. If you have access to antigen tests, you may remove your mask sooner than day 10 if you have 2 sequential negative tests 48 hours apart. If your antigen results are positive, you may still be infectious. You should continue wearing a mask and wait at least 48 hours before taking another test. Continue taking antigen tests at least 48 hours apart until you have two sequential negative results. This may mean you need to continue wearing a mask and testing beyond day 10.

Instead of quarantining if you were exposed to COVID-19, CDC recommends that you wear a high-quality mask for 10 days and get tested on day 5.

It is important to speak with your healthcare provider to determine the appropriate course of treatment if you become infected with COVID-19. Not all patients with COVID-19 will require medical treatment, and most people recover within two (2) weeks without any specific treatment. Medication, hospitalization, and respiratory support may be necessary for severe cases. Treatment generally focuses on managing symptoms and minimizing exposure to others for mild cases.

You may be eligible for COVID-19 medical treatment, including drugs or antibody therapy. Antibody therapy can help treat COVID-19 symptoms and prevent them from getting worse for individuals at high risk for disease progression. Healthcare providers can determine whether medical treatment is appropriate. Speak with one of our healthcare providers to see if it’s right for you.

Additional information concerning treatment is available on CDC’s website.

The best way to protect yourself from COVID-19 is to get vaccinated. Vaccinations are effective and help protect you and others from getting very sick from the virus. Following all CDC recommendations (e.g., wearing a mask, social distancing, washing hands, and getting tested), in addition to getting vaccinated, can minimize the possibility of infection.

COVID-19 is very contagious. The risk of getting COVID-19 depends on many factors, including close contact with people who have symptoms of COVID-19. It is essential to follow federal, state, and local government guidance to protect yourself from exposure.

Coronavirus disease (also called COVID-19) is an infection caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus), one of the most recently discovered types of coronaviruses. Those who have this disease may or may not experience symptoms, which range from mild to severe.

People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. Anyone can have mild to severe symptoms.

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

This list does not include all possible symptoms.

If you think you have been exposed, it is important to closely monitor for symptoms. Seek medical attention immediately if you develop severe symptoms, especially if you experience:

  • Severe trouble breathing (such as being unable to talk without gasping for air)
  • Continuous pain or pressure in your chest
  • Feeling confused or having difficulty waking up
  • Blue-colored lips or face
  • Any other emergency signs or symptoms

An antibody test checks to see if you’ve developed antibodies against COVID-19, which occurs after being exposed to the virus. Antibody tests do not show whether a person is currently infected. A molecular test checks for genetic material (viral RNA) produced by the virus. It determines if you’re currently infected and can spread COVID-19 to others.

You should get an antibody test if you’ve been previously exposed or believe you’ve been exposed to COVID-19 and want to see if you have developed antibodies. You should get a molecular test if you think you have an active COVID-19 infection.

No, antibody tests do not show whether a person is currently infected. Therefore, they should not be used in place of a molecular test to diagnose a current infection.

Yes, antibody tests can complement molecular tests by providing information about exposure and how the immune system responds to COVID-19 infections.

You do not need to do anything to prepare for the test. You do not need to fast or stop taking any medications before testing.

COVID-19 Antibody

There are three different types of antibodies: IgM, IgG, and IgA.

  • Immunoglobulin M (IgM) is usually produced as the body’s first response to an infection. However, for COVID-19, IgM antibodies are produced around the same time as IgG antibodies. Generally, IgM may provide short-term protection and can help tell if an individual has been recently infected.
  • Immunoglobulin G (IgG) is the most common type of antibody. It’s usually made several days to weeks after most infections. However, for COVID-19, IgG antibodies are produced around the same time as IgM antibodies. Generally, IgG remains in the body and may provide long-term protection against future exposure.
  • Immunoglobulin A (IgA) is found in the blood, sinuses, lungs, and stomach. Generally, IgA helps protect these areas from infection. However, it’s unknown what role these antibodies play in determining exposure or immunity to COVID-19. There is not enough evidence at this time to suggest that people who have these antibodies are protected against future COVID-19 infections. Visit the CDC website for further information.

Based on the most current research, antibodies develop around 1 to 3 weeks after infection from COVID-19. However, this varies by individual, and some people may take a longer time to develop antibodies.

Antibody tests do not show whether a person is currently infected. A molecular test is a more reliable indicator of current COVID-19 infection.

Yes, you can have antibodies from an asymptomatic COVID-19 infection. An asymptomatic infection is when you are infected but do not show any symptoms.

COVID-19 Molecular

The test can show a negative result even if you are infected with COVID-19*. This can happen if:

  • It is too soon for the test to detect the virus.
  • There was a problem with your sample or the test itself. No test is 100% accurate at all times.
  • If your results are negative and you’re having symptoms, continue to follow isolation precautions and ask your healthcare provider if you need further testing.
  • If your results are negative and you don’t have any symptoms, continue to monitor for any symptoms up to 14 days after your last possible exposure.

*Although the possibility is low, a false negative result should be considered if you have had recent exposure to the virus along with symptoms consistent with COVID-19.

This test can show a positive result even if you are not infected with COVID-19. This can happen if there was a problem with your sample or the test itself. These tests have been designed to minimize false positive results. If you are concerned about the accuracy of your results, ask your healthcare provider if you need further testing.

Indeterminate means that the test did not detect a clear positive or negative result. It was unable to accurately detect COVID-19. Your result could be indeterminate if:

  • You are infected with COVID-19 but the test was done too early to detect the virus, OR
  • There was a problem with the sample you provided or the test itself. It is recommended that you get retested or see a healthcare provider to discuss your result and confirm next steps. To get retested, please directly contact the company from which you ordered the test or ask your healthcare provider about testing recommendations.
Sexually Transmitted Diseases (STDs)

Sexually Transmitted Diseases or (STDs) are infections that are spread from one person to another. STD’s are very common and are usually spread during vaginal, anal, and oral sex. Unfortunately many people who have STD’s do not have any symptoms or do not show symptoms for long periods of time. STDs can lead to serious health problems without treatment, but the good news is that getting tested is easy. Many STDs are easy to treat with early detection. For more information please visit:

Different sexually transmitted diseases (STDs) have different tests. The kind of test a person gets will depends on the type of STD, symptoms, medical history and his or her sexual history.

It is important to get tested for STDs because if left untreated they may cause serious health problems.

Consider getting tested if you:

  • Are sexually active
  • Have had unprotected sex
  • Have had multiple sex partners
  • Have shared injection drug equipment
  • You are experiencing symptoms of a sexually transmitted disease
  • You are entering into a new sexual relationship
  • You have received a notification from a previous partner that they are infected
