Yes, we perform a highly sensitive RT-qPCR test for viral genetic material in your saliva. Our test is 100% specific for SARS-CoV-2, the coronavirus which causes COVID-19.

Collection of saliva samples provides a minimally invasive method of sample collection that can be reliably self-administered [1].

Reliable self-collection of saliva decreases the risk of transmission to healthcare workers and isn’t subject to disruption of the supply of swabs, transport media, and personal protective equipment necessary for healthcare providers to obtain quality swab samples [1,2].

Furthermore, saliva sampling provides greater sensitivity in comparison to throat or nasal swabs, that is less subject to variations in sample acquisition. Making it more likely that we can detect earlier into disease onset. [1,2].

If you have been infected by SARS-CoV-2, not only can it make you ill but you can also transmit the virus to other people. When infected, there is a chance to fall seriously ill. This is especially dangerous for people belonging to ‘at risk’ groups such as the elderly or people with pre-existing health conditions (such as diabetes, asthma and heart disease).

At HALO, we believe the best way to combat COVID-19 is through widespread testing and tracing. This allows identification of both symptomatic and asymptomatic carriers of the SARS-COV-2 so they can self isolate, minimising the risk of transmission. This not only gives those who are free of the virus a greater sense of security when returning to work and everyday life but also is the most effective way of protecting the health of your loved ones and your community.

This is exemplified by countries such as South Korea that have employed mass testing and contact tracing as key components of their strategy in reducing the number of confirmed COVID-19 cases [3].

HALO believes that weekly testing - when combined with other countermeasures such as hand washing, mask-wearing and social distancing, provides a sensible balance between the cost of screening and the benefit to not only our customers but also the wider community.

Some people, especially those with jobs requiring frequent face to face contact with numerous people such as; receptionists, drivers and healthcare workers have a greater risk of contracting COVID-19. This increased risk of exposure to SARS-CoV-2 may necessitate a higher frequency testing, making use of our incredibly sensitive test to detect SARS-CoV-2 as early as possible before the risk of widespread transmission to anyone they come into contact with on a daily basis raises significantly during the progression of COVID-19.

Each testing module is capable of over 250,000 tests per week. Although we have short term limits imposed by equipment, consumables and space, we can rapidly scale up our number of labs to meet any demand.

We currently have a testing laboratory in London however we are planning to expand both across the UK and overseas throughout 2020.

We will only test you at home under two circumstances:

  1. When you first set up your HALO account.
  2. While in Quarantine, in the unfortunate event that your test results come back positive.

This ensures that only users who are not currently infected by SARS-CoV-2 can safely enter back into the workplace, reducing the spread of the virus and easing workplace anxieties about catching the virus.

We are a multidisciplinary team of highly skilled: computer scientists, medical experts, molecular biologists and business experts who have combined forces to get the world back to work and restore a sense of normality, one test at a time.

The higher your viral load (the amount of virus present in your saliva), the more likely it is to be detected. This amount increases at the start of the infection We use a highly sensitive RT-qPCR test capable of detecting SARS-CoV-2 at lower viral loads than any other test available on the market. Internal tests correctly identified the virus in 100% of tested samples when the viral load 1000 times lower than amounts typically found in patient saliva.

Furthermore, our test is 100% specific to SARS-CoV-2 and is capable of detecting all known strains. This means that, unlike other testing approaches, you won’t receive a false positive test if you are infected by another virus, meaning you can return to a safe place of work faster and won’t have to quarantine unnecessarily.
