Our Tests | PCR, Serology & Antigen

We offer you the tests and solutions to protect your people, your customers and your business.

Unilabs offers your team or your customers the answers to their two most pressing COVID-19 questions:

  • Do I have COVID-19 now? – Unilabs’ PCR test
  • Have I been exposed to SARS-CoV-2? – Unilabs’ Serology test

By offering both tests on your terms, Unilabs can help protect your people, your customers and your business in the post-COVID-19 world.

WHICH TEST IS RIGHT FOR YOU? 

Tests are only useful if they fit the clinical context of your business’ employees.

We provide you with a simple questionnaire to help you identify who to test. Questions are focused on the past and current symptoms.

Laboratory analysis gives you an essential portrait of past and current infection across your organization. Our range of programmes offer one-off tests for those looking for a current snapshot, or enduring regimens for businesses in need of ongoing monitoring. PCR and Serology testing both play an important part in most scenarios

OUR MEDICAL QUESTIONNAIRE

OUR MEDICAL QUESTIONNAIRE: 

Our experts have designed a medical questionnaire to allow you to identify current and past relevant symptoms and triggers such as fever, cough and shortness of breath.

Our accredited labs are at the forefront of COVID-19-diagnostics innovation; partnering with us gives you access to the most current testing techniques.

COVID-19 TESTS AT A GLANCE:

PCR TEST

What it is:
Molecular diagnostic analysis (amplification of nucleic acids by PCR) for SARS-CoV-2 (agent of COVID-19)

Test objective:
To determine with certainty whether an individual is currently and actively infected (and therefore contagious) to break the transmission chain.

Typically used to:
Identify people who are contagious to others.

Required sample:
A nasopharyngeal or oral swab

Coming soon: Saliva collection – for a more comfortable experience and the possibility of at-home collection.

SEROLOGY TEST

What it is:
Serology testing of antibodies against SARS-CoV-2 (agent of COVID-19)

Test objective:
To identify whether an individual has ever been infected (and therefore has a degree of potential immunity).

Typically used to:

  • Understand what percentage of the population has already had COVID-19
  • Potentially identify a certain degree of “immunity” (although with a high degree of uncertainty)

Required sample:
A blood sample

 

COMING SOON: ANTIGEN TEST

What it is:
Antigen tests work by detecting the presence of SARS-CoV-2 specific viral proteins in the mouth and throat of patients.

What are the positives of antigen testing?
The main benefits are speed, lower cost and that it’s simpler to process. The test does not require complicated machinery and results are ready in minutes rather than hours.

What are the limitations?
Antigen testing is less sensitive than PCR (and other NAAT tests). Antigen tests work best with high viral loads, generally within 2-4 days after the onset of first symptoms. While false positives will be rare, infected patients with lower viral loads may show up as false negatives.

The test may thus miss infected patients in the early asymptomatic phase - and if they have a mild infection. In both scenarios, the patient may be infectious to others.

Test objective:
Taking its limitations into account, antigen testing is a useful first line of defense, especially where PCR testing is not available, helping to quickly screen and identify symptomatic Covid-19 patients.

When is antigen testing useful?
In situations where fixed groups of people need to be tested on a repeated, ongoing basis: for example, in hospitals, retirement homes, schools or prisons.

When is antigen testing not useful?
Sampling for antigen tests needs to be done by qualified, trained medical professionals, therefore so far not approved for home testing.

Given some of its limitations, the WHO does not currently recommend antigen testing at airports, or in areas of low prevalence, for example.

Required sample: A nasopharyngeal swab.
