Long COVID: An Overview

Long COVID is when an individual who has contracted COVID-19 continues to experience symptoms of the virus (e.g. tiredness, fever, sleep difficulty, neurological, cognitive symptoms and more…), which are often severe, several weeks/months after initial infection. Over 2 million people in the UK have been affected by Long COVID and an estimated 20 million in the USA.

While symptoms experienced vary, some of the main areas symptoms are impacted include the nervous system, gastrointestinal tract, immune system, cardiovascular system and of course the respiratory system.

At Attomarker, we believe we are approaching potential answers to pressing questions on Long COVID. Antibodies are a vital part of our immune systems. When analysing patient antibody responses across a range of COVID variants, it is evident that individual immunity and hence how vulnerable a person is, noticeably varies. We call these individual responses immunity endotypes.

Key Statistics


Around 2 million people in the UK have been affected by Long COVID


Estimated 20 million in the USA have been affected by Long COVID


Long Covid has negatively impacted over 1 million individuals’ daily lives and routines in the UK


Feeling exhausted/fatigued is one of the symptoms most reported by individuals who have long COVID

Attomarker Multi-Variant Antibody Immunity Spectrum Test

Adding Insight into the Immunology

Behind the Science

We have developed a Multi-Variant Antibody Immunity Spectrum Test, only requiring a fingerprick of blood, that we believe could be used in targeting treatments for Long Covid patients. It is a research test that, unlike our CE marked test, is not yet licensed to be sold to the public and is not available on the NHS, but the good news is that this promising new test and any subsequent treatment can be arranged privately with an appropriate clinician on a named patient basis. The clinician would be interested in your antibody immunity spectrum and seek to identify your endotype. The immunity spectrum could then inform a possible treatment in discussion with your doctor (please keep in mind that some drugs may be expensive).

We have formed a partnership with a clinic specialising in Long COVID (note this is a private clinic).
