Saliva as Medical Assessment Medium

Saliva is increasingly recognised as an excellent first-line option for noninvasive diagnostic assessments. Easily obtainable specimens can be used to detect many analyte types, including proteins, DNA, RNA, hormones, drugs, and others.

RapidDx Devices for rapid saliva testing

Saliva-based diagnostics for diseases of the ageing and traumatic brain injuries

Although saliva is painless to obtain, an effective and simple mechanism for the collection and testing of oral fluids is essential. Enter the patented Rapid Assessment Device (RAD) by RapidDx, designed to be a true game changer in diagnostic technology.

The RapidDx device has been described as a ‘lab in your hand’. The world became accustomed to using these types handheld products during the COVID-19 pandemic. However, compared to COVID-19 home tests, the RapidDx device will be less complicated. Here is how it will be used:

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.

Assessment devices for different conditions

The use of the device varies according to the disease or condition being tested. For example, the RapidDx RAD for concussion assessment is designed to be an over-the-counter (OTC) product kept in a first aid kit, a handbag, or a car to enable a rapid response to falls, vehicle accidents, sports injuries, and other traumatic events.

The RapidDx RADs for Alzheimer’s or Parkinson’s diseases will use a different portfolio of biomarkers that are specific for such diseases and quantitatively calculated in saliva specimens. In this case, a medical professional should explain the quantitative data to the patient, offer appropriate counseling, and recommend courses of action for both the patient and their caregivers if the test results are positive.

Alzheimer's

Alzheimer's

If we’re able to catch the disease sooner, we’ll be able to give patients more options for treatment and social services, as well as participate in clinical trials and other research opportunities.

About Alzheimer's

Parkinson's

Parkinson's

Parkinson’s disease is notoriously difficult to diagnose in the early stages. With RapidDx’s Parkinson’s device, a doctor can quickly assess the presence of Parkinson’s specific biomarkers, during a consultation.

Traumatic Brain Injury (TBI)/ Concussion

Traumatic Brain Injury (TBI)/ Concussion

RapidDx is developing a Rapid Assessment Device to quickly and accurately measure the presence of micro-ribonucleic acids in saliva. These molecules are released within minutes of head impact.
