Welcome to the COVID-19 Antigen Testing Program Guide

Thank you for partnering with the California Department of Health Valencia Branch Lab and Color to set up a COVID-19 antigen testing program. This guide will cover:

  • Software that manages check-in, sample collection, and return of results
  • On-site antigen testing

Site Software

In order to register people to get tested and to process their tests, you’ll use Color’s software. Below are the steps you’ll need to take to set up your account and to use the software on testing days.


On testing days your role may cover a number of areas, including checking in participants, collecting samples, and reading test results. More details about those steps can be found below.


Create your Color account

Head to home.color.com/create-account. Enter your organization email, and set up a password.

We’ll send you an email to confirm your email address once you’ve created your account. After confirming, your account is ready for use. On testing days, you’ll log into our onsite tool with your Color account credentials.


Get the technology you’ll need

Color’s software requires internet connectivity via WiFi or cellular service. 


If you’re using WiFi-only devices like laptops or tablets, make sure you have strong and reliable WiFi coverage in your testing area.


If your WiFi isn’t reliable, we recommend using portable hotspots from a cellular network provider, like this Verizon Jetpack® MiFi® 8800L


If you’re planning on using cellular devices, like a WiFi + Cellular iPad, be sure to select the appropriate cellular network provider that provides the best coverage for your area, like AT&T or Verizon.

Each site administrator should have their own device. We recommend three stations: check-in, sample collection, and resulting. Note that scanning does not occur at check-in. 


iPads must be running iOS 13 or iOS 14. For example, the 10.2” Wi-Fi + Cellular iPad, model MYN32LL/A works well. We recommend you also download the Google Chrome iOS app.


Android tablets must be running Android version 9, 10, or 11 with the latest updates and the latest version of Google Chrome. For example, the Samsung tablets, such as the Galaxy Tab A 8.4” Cellular, work well. 


Laptops should have 1 usable USB-A port if you will be connecting a wired barcode scanner. 


We recommend using the latest version of Google Chrome on your devices.

2D barcode scanners must be used to read the DataMatrix codes printed on each Abbott BinaxNow card.


If you are using an iPad, we recommend using the ScanKey iOS app which enables usage of the iPad’s camera as the barcode scanner from within the virtual keyboard interface. 

  • To set up ScanKey – Go to the iPad Settings → General → Keyboards and then make sure that only the ScanKey keyboard is there. Delete any other keyboard.
  • If ScanKey does not show up in the App Store, please update your iPad to the latest software.
  • Here are instructions on how to setup ScanKey on your iPad.


If you are using a handheld scanner, the scanner must scan two-dimensional (2D) barcode labels. We recommend using wired USB scanners, because wireless or bluetooth scanners can be difficult to pair and ensure connectivity throughout the day. If you choose a wired USB scanner, you’ll need a Lightning to USB 3 Camera Adapter for iPad, or a USB OTG adapter, like Micro USB or USB-C, for an Android tablet. Adapters may vary between devices.

Be sure to maintain the battery levels of your devices throughout testing days to enable continuous usage, and consider charging overnight. iPads will require at least a 12-watt (2.4 amp) USB power adapter. If supporting multiple iPads or other USB-charged devices, we recommend using a multi-port USB charger.

Testing Days

On testing days your role could cover a number of areas, including checking in participants, collecting samples, and reading the results.

Checking in Participants

Participants will be listed in the Eligible tab of Color’s antigen onsite tool. The information will be collected ahead of time from your testing site lead.

Administering Antigen Tests

  1. From the “Checked In” tab, select your patient and confirm their identity
  2. Re-confirm their consent and assign them an Abbot BinaxNow antigen testing card
  3. Scan the QR code with your device to link the card to the patient
  4. Collect the sample according to the manufacturer’s instructions
  5. As soon as you have collected the sample, immediately start the timer.

Recording Results

  1. Results must be read after no less than 15 minutes and no more than 30 mins. 
  2. When the status changes to “Read Results,” read the antigen card, scan the QR code, and record the results in Color’s antigen onsite tool. 
  3. You can also show the patient their results on your device. We do not recommend disclosing PHI verbally in a communal space.

Frequently Asked Questions

  • Ensure the scanner is properly connected to your device, if using handheld
  • Try restarting your device
  • Click your name in the top right corner and choose “Sign out” from the dropdown menu that appears. Sign back into your account and try again.

Let the timer expire for this sample. You will see the status change to “too late,” and can then retest the individual if they are available.
