Between July and September 2022, a total of 4,310 laboratory reports of hepatitis C were reported to UKHSA previously PHE).

There was a 51% increase in the number of reports compared to the first quarter of 2020 (n=2,179). This increase is due to the addition of previously missing backdated confirmed hepatitis C laboratory reports originating from either the private laboratory Abbott (formerly known as Alere) or a laboratory from the North West region. 听听听

Since 2017, one laboratory in the North West of England has undertaken hepatitis C dried blood spot testing alongside hepatitis C routine laboratory testing. This single laboratory has taken on testing for a large part of the country; however, some samples where geographical information is lacking,听may have been incorrectly assigned to this specific laboratory rather than the laboratory from which the sample originated.

Age and sex were well reported (97% complete). Where known males accounted for 70%听of reports (2,931 out of 4,199) which is consistent with previous quarters and years (1). Adults aged 35 to 54 years accounted for 31% of the total number of hepatitis C reports.

Individuals aged under 1 year are excluded, since positive tests in this age group may reflect the presence of passively-acquired maternal antibody rather than true infection.

Laboratory reports are not reliable for differentiating acute and chronic hepatitis C infections. Laboratory reports include individuals with a positive test for hepatitis C antibody, antigen and/or detection of hepatitis C RNA.

A small proportion of these specimens are diagnosed following DBS testing, however not all DBS testing is reported by laboratories.

In Table 2, laboratory reports are presented broken down by Operational Delivery Network (ODN). ODNs were launched in July 2013 following the publication of the NHS England strategy to sustain and develop clinical networks.

ODNs are the networks through which hepatitis C treatment is being delivered across England. Between July and September 2022, 4,185 out of 4,281 individuals in England had been allocated to an ODN.

ODNs are based on NHS England Clinical Commissioning Groups (CCGs) geographic boundaries. NHS England allocates a primary or lead ODN for CCGs which may cross more two ODNs.
