Helping you get back to work safely, quickly (1-2 day turnaround time) and effortlessly.  Watch the videos linked below to see just how easy it is.

Employers and administrators have trusted Collection Plus for 30 years to provide fast and accurate results for drug/alcohol abuse testing and more. We are pleased to announce that we are ready to provide COVID-19 testing, through our partner Clinical Reference Laboratory, to get employees safely back to work.

Your approach to mitigating the risk around preventing, detecting and controlling an outbreak, can be as much as establishing a baseline and regular testing at set intervals to simply just taking temperatures. All businesses have to make a decision and weigh how much they are willing to invest versus what level of risk mitigation they desire. You may also wish to consider how much you wish to give your employees’ families peace of mind about being safe at work.

We have a client that is employing an outside medical staffing company to be at the entrance gate to a complex on a 24 by 7 basis. These two medical personnel are taking temperatures and checking for physical signs and symptoms. Another is having us perform those functions, but only for prospective employees coming out of the union hall. Yet another is taking temperatures at the time their drivers start their shifts. One has even installed thermal scanners at all entrances. Taking temperatures and looking for signs and symptoms is the easiest to implement and can be the most cost effective. But we all know that it is subjective and not very accurate due to the fact that a virus carrier may be asymptomatic.

When reviewing the FAQ’s at the end of this page, you see we acknowledge the fact that there is not a “one shot” detection or cure. So what is your best option?

While not perfect, a two-step process of detection and confirmation allows you to do a number of things. This two-step process consists of first testing for antibodies and then testing for actual infection of the cells (PCR). It needs to be as accurate as possible, with ease of implementation and a quick turnaround time. Look to the FAQs for further information about these terms.

We feel we have a great solution that is scalable for a number of strategies. Your cost can correspond to the level of prevention and the level of detection you desire.

The following information is the best guideline to follow, based upon recent CDC guidance.

Our guidance is a three-step process

First, establish a baseline for the entire asymptomatic population.

  • If not currently conducting temperature checks, then conduct antibody testing. If positive, use PCR testing to confirm if someone is contagious. A medical professional then takes over to help the employee.
  • If currently conducting temperature checks, then have some PCR kits on hand to confirm if someone is contagious. A medical professional then takes over to help the employee.

Next, have some form of contact tracing process in place in the event that someone is identified as testing positive for the virus.

Lastly, if there is an outbreak, then provide PCR kits to determine who has contracted the virus. Ensure those awaiting results are isolated until results become available.

The information below gives you an overview of our lab partners’ Return to Work solution (FDA approved).

We look forward to answering any additional questions you may have. We will work with you to help you determine which approach is best in keeping your employees safe and healthy and in reacting quickly and minimizing any outbreak. or 916-487-3152 x.9

CRL developed a new COVID-19 “Return to Work” solution using the FDA approved new “Roche” antibody tests. Our program has (2) distinct facets:

CRL Clear

CRL COVID Clear (Asymptomatic population using Dry Blood Spot (DBS) Antibody/IGA, IGM & IGG Testing)

CRL Rapid Response

CRL Rapid Response (Symptomatic population using an ORAL SWAB(PCR/Molecular Testing)


Step 1: CRL will ship supplies in bulk to designated client location(s) or, can ship directly to your associates homes (for an additional cost)

Step 2:  Begins with an online donor registration process using our CRL COVID Clear Application, entering donor demographics & then responding to a short questionnaire (similar to, 23&me etc.).

Step 3:  Donor performs a self-collected DBS (Dry Blood Spot) Collection & the donor ships the specimen to the Lab using CRL’s prepaid FedEx shipping supplies.

***If at any point during the registration process, donor indicates they are symptomatic, then they are directed to discontinue the DBS Collection & Supplies for the “CRL Rapid Response”/Molecular home-based saliva collection will be shipped to the associate overnight.

Step 4: Once the “Saliva” Collection kit is received, the donor follows the online instructions to complete the self-collection & ship the Sample to the Lab using CRL’s prepaid FedEx shipping supplies.

Step 5: Non-reactive/negative results are reported directly back to the employer & the associate. At time of registration the associate will have the option to receive those negative results email or text.

Step 6: Associate reactive/positive results are reported to the employer & ordering physician who will contact the donor with the result & additional instructions regarding self-quarantining etc.

CRL has partnerships w/”Ordering Physicians” in every state that may be utilized or you may use your own “Ordering Physician”. CRL will fulfill all mandatory statewide reporting requirements.


Client Provides Supply Order Details

CRL ships DBS collection kits per client supply order request.

Immunity is the ability of an organism to recognize and resist invasion or infection. This is largely through the action of different antibodies. In the case of case of COVID-19, there is not yet enough data determine whether there is long term immunity.

Antibodies are proteins found in the blood. They help respond to and attack invaders (such as COVID-19). There are multiple types of antibodies. IgM antibodies are made the MINUTE an invasion occurs and wear off once invasion/infection is over. IgG antibodies are made to last after an infection is GONE and tend to last longer- in some cases for a lifetime. Reference the chart below.

IgA (also referred to as sIgA in its secretory form) is an antibody that plays a crucial role in the immune function of mucous membranes.

An antibody test is one that aims to recognize specific antibody proteins – usually through blood tests. For COVID-19 in particular, antibody testing. The CRL screening test looks for the presence of IgG, IgM and IgA antibodies.

A toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies.

The first test – the screening test, is a Dried Blood Spot that is exposed to an antigen in the lab and looks for specific antibodies and then “marks” it as positive, if found.

The next test – A confirmation test is a Polymerase Chain Reaction (PCR). We believe this to be the best and most specific method to identify an active, infectious disease in your body and in specific cells. See same chart below.

In medical diagnosis, test sensitivity is the ability of a test to correctly identify those who carry the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those who are not carriers of the disease (true negative rate). In order to determine usefulness and reliability of testing, both of these should be taken into consideration. As it relates to COVID-19 antibody testing, a test with high sensitivity and specificity would best provide true positive and negative results. Roche’s COVID-19 antibody test is able to identify those with COVID-19 100% of the time (sensitivity rate) and able to correctly identify those without disease in 99.8% of samples (specificity rate).

See Attached Roche release.

Yes the data is secure. Our clients will access employee test results on the Collection Plus CRL Oasis website, which use individual passwords. Each client will have their own exclusive sub-account for their specific company’s results. This platform is HIPAA compliant.

You and your designees will have a Collection Plus sub-account just for your company. Employees can also opt into receiving their individual results.

  • They are overnighted but with all the demand, plan on 2-3 days.
  • We recommend having a few on hand if you are using them for an outbreak.
  • You only pay the $20.00 until you send in the test
  • Turnaround on DBS result is 1-2 days.
  • Yes, that is an option, if you believe you have an outbreak and symptomatic population.
  • The price for this Saliva test kit is $47.00 versus $20.00.
  • A less expensive option is to provide the DBS kit and as the employee registers, if they indicate symptoms, they will be asked to disregard the DBS and will be shipped a Saliva test kit.
  • Turnaround of PCR test is 2-4 days

We can Provide you an Excel spreadsheet for you to evaluate various strategies. Please email your request to Look for that under another separate cover e-mail

We are working to provide any company expressing interest, as evidenced by being set up in our system, one DBS test kit to use and see how the process works. We will credit the cost of that process to the sale of 50 kits or more. But we must wait for the EUA.

Both kits may be ordered in quantities of ten.

We suggest the testing be done on site. Appoint designees to help employees walk through the registration and collection process. The designees will only be there to oversee and answer questions, especially if there is a language barrier or the employee needs to access a computer due to the lack of a phone browser.

We are working on getting a video.

The process is easy, as the employee simply spits through a tube into a container to reach a set, marked level.

Both detection methods are PCR.  Testing methods are evaluated based on sensitivity and specificity. We feel comfortable that with FDA approval comes the validation of both sensitivity and specificity.

The Ordering Physician (provided by CRL at no additional charge) will do the following:

  1. Contact the donor/employee according to the method entered while registering the device
  2. Relay the result & quarantine information as directed by the CDC
  3. Advise the donor that they need to contact their physician for supplemental follow-up as needed
