COVID-19: Screening and Testing Best Practices [UPDATED]


The COVID-19 guidelines in this article are reflective of the time of writing. To stay up to date with the latest CDC guidelines visit the official COVID-19 site.

Navigating the waters of a global health crisis is probably not something you expected to do, and if you’re in panic mode, you’re not alone. This is unknown territory for many.

From executing daily screenings for essential workers to providing mass screenings and testing programs for those returning to campus after working remotely, you’ll quickly see that planning ahead is instrumental if you want to keep your business open and get back to normal operating procedures safely.

Here’s the bottom line: you want your people to come back to the workplace healthy, and you want them to stay well when they get there. So, how can you accommodate their return today and the unforeseeable tomorrow?

Safety First

First and foremost, make sure everyone is safe. The Centers for Disease Control and Prevention (CDC) now recommends the following to help decrease the spread and impact of COVID-19 in the workplace:

  • Promote frequent and thorough hand washing or use of alcohol-based hand rubs containing at least 60% alcohol.
  • Encourage workers to stay home if they’re feeling sick.
  • Encourage respiratory etiquette, including covering coughs and sneezes.
  • Practice social distancing by maintaining approximately six feet from others.
  • Promote video or teleconferencing to minimize face-to-face interactions.
  • Perform routine environmental cleaning and disinfection.
  • Educate employees on how to reduce the spread of COVID-19.
  • Wear cloth face coverings in public places where social distancing is difficult to maintain, including the workplace, running errands, and interacting with those outside of your household. However, do not use cloth facing coverings if someone has trouble breathing, is unconscious, incapacitated, cannot remove a mask by themselves, or is under the age of two.
    • It’s also important to note that cloth masks are different from surgical masks or N-95 respirators, which are critical personal protective equipment (PPE) and should be reserved for healthcare workers and other medical first responders.

The CDC also recommends that employers coordinate with their local and state health officials to ensure they have the most timely and accurate information to guide prompt identification and isolation of potentially infectious individuals in the workplace.

As healthcare providers carry out virtual or in-person screening and testing, ensure they have appropriate PPE like masks, gloves, hand sanitizer and eye protection. Next, you’ll want to make sure logistics like building entry, parking and screening patterns are properly controlled to further ensure both provider and employee safety.

Screening Best Practices

Return-to-the-workplace plans and protocol may look different for each organization. From manufacturing plants that are continuing to operate through the pandemic to expansive tech campuses whose employees are working remotely, having a plan will make a big difference in your ability to recover and resume normal operations after stay-at-home mandates have been lifted.

Essential Businesses and Workers

For businesses that have been deemed essential, the screening process can take place at the beginning of every day, each shift, and throughout the day as workers and visitors enter and exit the building. This should be conducted in-person provided screening personnel have the appropriate PPE needed to facilitate temperature screenings.

If possible, screenings should be conducted outside the actual building or campus to prevent a contagious person from entering the workplace and exposing others. This action helps prevent the need for extensive contact tracing and deep cleaning. If it is not possible to screen outside or prior to building entry, designate a specific, isolated area of the building for screenings that can be cleaned appropriately and daily without forcing an evacuation. This type of screening may be accomplished virtually without measuring temperature.

Remote Workers Returning to the Office or Campus

Once work-from-home restrictions have been lifted and buildings open back up, remote employees returning to the workplace can be screened before they re-enter the building at the beginning of every day, each shift, and throughout the day. This screening can take place in-person (provided appropriate PPE is available), or virtually by phone, video chat, or secure messaging.

Isolated Individuals Returning to the Workplace

Employees who have a presumed or confirmed COVID-19 diagnoses, and are in isolation, should be screened based on the CDC’s latest guidelines and clinical evidence. This process should take place virtually either by phone, through video chat, or secure messaging. A virtual-first approach keeps healthcare workers safe and reduces potential exposure to others in the workplace.

Testing Best Practices

There are two basic types of tests available for COVID-19: diagnostic and screening.

1. Diagnostic Testing

According to the CDC, not everyone needs to be tested (diagnostic) for COVID-19. Amid a pandemic with a disease that has essentially no known treatment it is important to determine who should be tested and who should not, given the limited supply of tests and an overburdened healthcare system.

When to use a Diagnostic Test for COVID-19

Individuals who have a known exposure to COVID-19, or symptoms of COVID-19 illness, should be tested by their healthcare provider using a diagnostic test.

In the workplace, an initial screening is the first place to start. This process involves a series of questions that may sound something like this:

  1. Do you have any reason to believe you have been exposed to coronavirus (COVID-19)?
  2. In the past 24 hours, have you experienced any of the following symptoms:
    • Fever of a 100.4°F (38.0°C) or higher
    • Cough
    • Difficulty breathing
    • Fatigue
    • Muscle or body aches
    • Headache
    • New loss of taste or smell
    • Sore throat
    • Congestion or runny nose
    • Nausea or vomiting
    • Diarrhea

If the individual answers “yes” to one or more of the questions or has a temperature of 100.4°F (38.0°C), there’s a chance they may have the virus and should be separated from others. Based on the individual’s response to the screening questionnaire, testing may be necessary and should be considered on a case-by-case basis. Decisions about testing are at the discretion of state and local health departments or the patient’s primary care provider.

When Not to Use a Diagnostic Test for COVID-19

Those who present with mild symptoms and do not have underlying medical conditions like heart or lung disease, as well as diabetes, may not need to be tested for COVID-19. Most people have mild illness and can recover at home – this is referred to as self-isolating. If someone is sick and self-isolates, they should closely monitor their symptoms in case their condition gets worse and additional medical attention is needed. The decision to test or not to test based on local prevalence rates should be made by the healthcare provider with consideration to local health department guidance.

For those not tested for COVID-19, the decision to end home isolation may be considered if certain criteria have been met. The decision to end home isolation should be made in consultation with the individual’s healthcare provider and state and local health departments.

2. Screening Testing

Antigen testing as a screening program is an infection containment strategy that will assist in identifying employees with early COVID-19 who may not be symptomatic and therefore not captured in daily screening programs. With its rapid turnaround time, and antigen testing screening program is an effective strategy to prevent infection in the workplace. Especially in a high prevalence situation, the risk of not detecting all cases or risk of false negative results is balanced out by the timeliness of serial testing.

Our Recommendation

Premise Health recommends organizations utilize both screening and testing programs when solving for the preservation of workplace and workforce health and safety. Whether used for the continued work of essential employees or the reopening of a building or campus as a work-from-home workforce returns to the physical workplace, screenings will help identify high-risk, contagious individuals, and testing will help track and contain cases across the workforce. We recognize helping employees continue working or return to work safely is critical to preserving jobs and companies, as well as preventing future outbreaks.

Reassurance That Comes with a Plan

During these challenging times, having a plan is crucial as you navigate the immediate and future needs of your workforce and their families. Even more important is having a trusted partner who can guide you through the process.
