RapidDx Devices

A lab in your hand - saliva tester by RapidDx

A ‘lab in your hand’

The user-friendly patented RapidDx Rapid Assessment Device (RAD) will be designed to facilitate the process of saliva collection and testing. The device will play an important role in the detection of neurodegenerative diseases such as Alzheimer’s and Parkinson’s and in assessing conditions like traumatic brain injury/concussion.

How the RapidDx Rapid Assessment Devices will work

How the RapidDx device works

Step 1

User inserts saliva absorption pad into the cheek or sub-lingual pocket

Step 2

Red ‘indicator’ dot informs user sufficient saliva has been collected

Step 3

User inserts collection wick into the device

Step 4

User turns the knob, compressing saliva to the test strips

Step 5

Test lines indicate positive/negative result
The RapidDx RAD uses lateral flow immunochromatography technology as a testing platform. Inside the device, test strips are treated with specific antibodies that correlate with the disease or condition being tested. The strip will have a pre-established threshold for the disease, detecting the biomarker of choice at a specific cut-off level. If the concentration of such a biomarker in an individual’s saliva is greater or equal to the threshold, a (Test) line will appear, indicating a positive result. Additionally, a ‘control’ line (C) will appear to indicate a correctly completed test.

What the RapidDx RAD assesses

The RapidDx RAD will be a versatile device used for testing various diseases and conditions. For example, the RapidDx RAD for concussion assessment is designed as an over-the-counter (OTC) product for a quick response to falls, sports injuries, vehicle accidents, and other traumatic events, while the RapidDx RADs for Alzheimer’s or Parkinson’s diseases utilize specific biomarkers quantitatively measured in saliva samples. Medical professionals play a crucial role in interpreting the data, providing counseling, and recommending appropriate actions for patients and caregivers based on the test outcomes.



If we’re able to detect Alzheimer's sooner, we’ll be able to provide patients with more options for treatment and social services.
