COVID-19 Testing

At Omniya Clinic in London

Our responsibility is to ensure our patients receive accurate and reliable testing services.  As a result, we have partnered with the largest independent provider of clinical laboratory diagnostic services in the UK to offer both COVID-19 Tests: Abbott Antibody and PCR (Swab).


1. Abbott IgG Antibody COVID-19 Test:

Detecting IgG Antibody, which will confirm whether you have been exposed to COVID-19, and produced an immune response. 

The Abbott IgG Antibody test is approved by Public Health England. It is a CE marked, automated, interfaced, laboratory test (14 days or more after onset of symptoms).

Sample Type: SST/Serum
Turnaround Time: 1 to 2 working days
Price: £95 (20% discount for NHS Staff and Key Workers)
Consultation (optional): £100

2. PCR (Throat Swab) COVID-19 Test:

Detecting whether you currently are infected with SARS-CoV-2

Sample Type: PCR swab
Turnaround Time: 2 -3 working days
Price: £150 (20% discount for NHS Staff and Key Workers)
Consultation (optional): £100

3. SARS-CoV-2 Rapid Antigen Test (Roche):

Sample Type: Nasal swab
Turnaround Time: 15 minutes
Price: £95 (20% discount for NHS Staff and Key Workers)
Consultation (optional): £100

Abbott IgG Antibody Coronavirus – COVID-19 (SARS-CoV-2)

Your immune system will react to the SARS-CoV-2 infection, and in turn produce antibodies (anywhere from a few days to 14 days and beyond). The specific IgG antibodies are produced in the later stages of infection to SARS-CoV-2, and are detectable after RNA is no longer detectable.

IgG antibodies will allow us to identify who has been infected by SARS-CoV-2.

Interpretation of Results

COV-2 IgG             < 1.4                 Not Detected                (Negative)

COV-2 IgG             >= 1.4              Detected                        (Positive)

Specificity: 100%
Sensitivity: 97.5%

The results of the Abbott IgG Antibody test should be used in conjunction with clinical evaluation and diagnostic procedures. It has also been recognised that there can be delayed responses in immunocompromised patients.

COVID-19 (SARS-CoV-2) Testing By PCR Assay


  • Nasal/Throat swabs.

Note, if you are performing the PCR Swab Test, please follow these instructions:

  • Samples are to be taken from symptomatic patients between days 1-5 from onset of symptoms
  • Send specimens to the laboratory at an ambient temperature. These should be in the Category B packaging and labelled as containing HIGH RISK specimen.
  • Please send samples on the same day that they are taken to ensure the laboratory is able to provide best results. Further note that samples are still stable at an ambient temperature for 3 days for wet swabs, and also up to 6 days for dry swabs, but we strongly encourage you to send the samples on the same day.

The assays used at our partner laboratory show:

  • A minimum sensitivity of 98%
  • A specificity of 100% with no cross-reactivity with other viruses.


The majority of people with COVID-19:

  • Have an uncomplicated or mild illness (81%)
  • Experience non-specific symptoms, which can include cough, fatigue, fever, muscle pain, sore throat, anorexia, malaise, dyspnea, nasal congestion, or headache.

Less commonly, although this is continually developing, patients may also present with nausea, vomiting and diarrhoea. Further, a loss of taste and smell has been reported in the infection near the onset, and as of 18 May 2020, is noted in the official symptoms list in the UK.

For high risk patients, particularly those aged above 70, reports state that a relatively small proportion of people may:

  • Develop severe illness requiring oxygen therapy (14%)
  • Require intensive care unit treatment (5%).

The above is a non-exhaustive list.

Current testing for COVID-19 (SARS-CoV-2) is rapidly evolving.

SARS-CoV-2 Rapid Antigen Test (Roche)

The SARS-CoV-2 Rapid Antigen Test detests the presence of the SARS-CoV 2 virus.

This rapid test is a reliable and accurate nasal swab, used in laboratory and point of care settings for both symptomatic and asymptomatic people. This can help healthcare professionals identify a SARS-CoV-2 infection in people suspected to carry the virus with results typically ready in 15 minutes. In addition, it serves as a valuable initial screening test for individuals that have been exposed to SARS-CoV-2 infected patients or a high-risk environment.

Tests are CE marked and meet the provisions of the Council Directive 98/79/EC for in vitro diagnostic medical devices

Sensitivity: 96.52%

Specificity: 99.68%

About Antigen Testing
An antigen test detects proteins which are structural or functional components of a pathogen and are thus very specific to that pathogen In this case, the test would provide a qualitative “yes/no” answer on the presence of the pathogen in the patient sample and can be offered as a rapid strip test that is performed at the point of care. If the target antigen is present in sufficient concentrations in the sample, it will bind to specific antibodies and generate a visually detectable signal on the test strip, typically with results ready in 15 minutes.
