Molecular Detection of Viruses in CSF
Within scope of accreditation
Viral meningitis is the most common type of meningitis. It is often less severe than bacterial meningitis, and most people get better on their own (without treatment). However testing to determine the viral agent can be indicated particularly for those viruses more commonly associated with more severe symptoms.
PURPOSE OF PROGRAMME:
To provide EQA for laboratories determining the presence of HSV-1 DNA, HSV-2 DNA, VZV DNA and Enteroviruses RNA in the CSF
MATERIAL PROVIDED: Freeze dried simulated CSF
DISTRIBUTIONS PER YEAR: 2
SAMPLES PER DISTRIBUTION: 6
FREQUENCY OF DISTRIBUTION: See annual distribution timetable
PROGRAMME OF ANALYSIS:
Results are entered online via the UK NEQAS secure website. The distribution is open for three weeks. Intended results are usually uploaded the day after closing date. Late results are not accepted after intended results are uploaded.
Qualitative detection, consensus. General descriptive statistics.
PERSISTENT POOR PERFORMANCE:

The first distribution of UK NEQAS for Microbiology was sent out by the then Public Health Laboratory Services on the 1st of May 1971 organised by Dr Peter Crone. This distribution consisted of one scheme, three bacteriology specimens, sent to 67 laboratories in the UK. One of our recent distributions consisted of 12 different schemes, comprising 8 bacteriology, 13 serology, 10 molecular and 9 mycology specimens, and sent to 53 countries representing over 1300 laboratories. UK NEQAS for Microbiology, operated by Public Health England, is a UKAS accredited proficiency testing provider No. 4715.
