Covid-19 antibody testing and self-test kits are being introduced by Nomad Travel.
Both tests have been authorised by Public Health England and claim a 98% accuracy rate.
The home testing service is being charged at £145 while the antibody tests in the agency’s clinics in Bristol, Cardiff, Manchester and the City of London cost £120.
The home-testing sample includes a swab from both the nose and throat which is to be returned for laboratory analysis. Results will be made available through a secure online portal along with information for understanding results.
Tests in Nomad Travel clinics will see a nurse take a blood sample while following PPE and hygiene guidelines.
This blood sample will then be sent for lab analysis to determine whether Covid-19 antibodies are present.
Results are expected within two to three working days.
A company spokesperson said: “Covid-19 infection testing is used for detecting the live coronavirus indicating current infection.
“You may want to use the coronavirus self-test if you currently have symptoms of the virus, such as coughing or shortness of breath.
“You may also choose to use this test if you have recently been in contact with someone who has had Covid-19 confirmed or has recently experienced symptoms.
“It is important to note that some people infected with Covid-19 do not experience symptoms. You do not need to currently be experiencing Covid-19 symptoms to take Nomad Travel’s Covid-19 at-home test.”
