A word on COVID-19 Antibody Testing
Hampton Knight do not oer COVID-19 antibody
testing; due to the current uncertainty surrounding
how long immunity resulting from prior exposure to
coronavirus may last, there is no strong evidence to
support its use in workplace settings.
Testing that’s tailored to your business
Hampton Knight work in consultation with all clients to
understand their specic needs and help them
determine the most appropriate testing solution for
their business. Their high-quality, fully-managed
Scalable solutions and exible delivery
• Expert collection technicians can carry out testing
onsite, at Medigold Health clinics or as a ‘doorstop’
test. Mobile units are available if you do not have
suitable testing facilities at your locations.
• Onsite sampling allows large numbers of
employees to be eciently tested in each session
(technicians can conduct up to 40 RT-PCR swab tests
or 30 rapid LFD tests per day). One-o and
short-notice requests can also be accommodated,
• Technicians are equipped with full PPE and
approved testing kits.
• Self-collection kits can be provided (for RT-PCR
swab tests only) as an alternative to onsite testing.
Kits are designed to enable employees to follow
secure sampling protocols with no training required
and contain everything needed to collect, package
and ship samples to the laboratory for testing.
• If you already have government-supplied rapid LFD
testing kits, we can provide training, guidance, and
clinical support, on-site or online, to ensure your
testers are performing tests accurately.
Rapid turnaround times
• Hampton Knight’s dedicated team are available
24/7 to manage bookings and carry out onsite and

and already had established relationships with a
number of private PHE and UKAS approved
laboratories, along with a substantial, UK-wide
network of specialist collection technicians.
With the onset of the coronavirus pandemic, they
were able to quickly pivot their operations, training
their technicians in the COVID-19 sampling process
and investing signicantly in developing their
infrastructure to support even larger-scale testing.
Committed to ensuring that they remain at the
forefront of COVID-19 testing, they have already
completed the rst phase of the Approved Provider

Since May 2020, they have carried out over 23,000
tests for clients across multiple industry sectors, from
broadcasting to transport and logistics.
Keeping it Simple – Reliable, eective antigen
Hampton Knight oer two types of COVID-19
(SARS-CoV-2) antigen test, both of which can
eectively detect the presence of the live virus to
conrm whether an individual is infectious, even if
they are asymptomatic.
COVID-19 RT-PCR Antigen Swab Test
With 99 per cent accuracy, this type of test represents
the ‘gold standard’ for COVID-19 testing. A throat and
nasal swab is used to collect a sample, which is then
sent to a laboratory for analysis, and results are
returned within 48 hours. Tests are usually carried out
by one of Hampton Knight’s specialist collection
technicians, but clients can also choose to purchase
self-collection kits that their employees can use to
collect their own samples at home.
Rapid Lateral Flow Antigen Test
Rapid testing is carried out using a throat and nasal
swab sample, which is then processed using an
extraction uid and a lateral ow device (LFD). This
type of test can produce results within 15-20 minutes
without the need for laboratory analysis. LFD tests are
signicantly cheaper than RT-PCR tests, but they also
have lower levels of sensitivity, meaning they may
produce more false negative results, particularly in
asymptomatic individuals. This risk can be mitigated
through more frequent testing. LFD tests should only
be carried out by, or under the supervision of, a fully
• Visits can be scheduled, and self-collection kits
shipped, with just 48 hours’ notice.
• Rapid LFD tests return results within 15 minutes.
• RT-PCR swab samples are sent for analysis via
same-day specialist medical courier or can be
shipped free of charge within 24 hours via Royal
Mail’s NHS Priority Mailbox network.
• Labs operate 24/7 to ensure RT-PCR results are
returned within 48 hours of receipt.
Clear reporting and end-to-end support
• Hampton Knight oer a fully managed service that
incorporates the reporting of all test results to SGSS
at PHE, in accordance with government guidelines.
• RT-PCR swab test results are returned to employers
securely via email in a GDPR-compliant and
easy-to-interpret format, indicating either a positive,
negative, or inconclusive result.
• Specialist Occupational Health Clinicians are on
hand to provide medical guidance and ongoing
clinical support in all cases where a positive result is
• Clients are provided with regular management
information reports and access to supplementary
resources, documentation, information sheets and
training to support eective use of the service.

Testing Accuracy: The low-down on specicity
The accuracy of dierent types of COVID-19 test is
determined by two factors:
Specicity: if a test has high specicity, when a
positive result is returned, there is a high likelihood
of it being a true positive, i.e. the person is likely to
Sensitivity: if a test has high sensitivity, it is more
likely to pick up the virus in an infected person i.e.
there is less likelihood of it returning a false
No test is one hundred per cent accurate and
false positives and (more problematically) false
negatives do occur.
In some cases, tests may even return an
inconclusive result, meaning the laboratory has
been unable to determine whether or not a person
is infected with Covid-19 following analysis of the
sample provided, and a repeat test will be required.
It is also important to remember that if someone
tests negative for Covid-19, this simply means they
were at low risk of having the virus on the day they
gave their sample. It is still possible that they may
have subsequently been exposed to the virus since
being tested and could still test positive later.
Ensuring that tests are carried out regularly and
conducted by trained specialists is the best way to
guarantee that samples are t for analysis, reduce
the risk of false positive and negative results, and
get the best from your testing programme.
