2 2 Today’s talk What WE do to help choose laboratory practice Background to where Standard Methods ‘sit’ within the HPA Background to development of SOPs About the Genital Tract SOP How much do people like the SOPs? Do they use them? Where are the new developments with SOPs?

7 Evaluations Unit Keith Perry Microbiological Diagnostics Assessment Service

8 Results: Timing of Detection of Primary HIV Following seroconversion * = combined antigen-antibody= immunometric = Class specific antibody capture = antiglobulin / indirect * based on 38 seroconversion panels

9 Quality Control Reagents Unit AxSym (Abbott Diagnostics)PRISM(Abbott Diagnostics) Vitros (Ortho Clinical Diagnostics) VIDAS (bioMerieux) ACCESS (Beckman Coulter) Joe Vincini – Quality Control Reagents Unit

10 Quality Control Reagents Unit  Supplying clinical laboratories with IQC reagents  Providing advice on best use of our reagents  Helping laboratories monitor the performance of kits and equipment  Providing help with problems associated with IQC  Providing news on products, new reagents and new projects Joe Vincini – Quality Control Reagents Unit

11 Quality Control Reagents Unit Quality Control Reagents include: ▪ Hepatitis C ▪ Syphilis ▪ CMV▪ Herpes Simplex ▪ Hepatitis B▪ VZV ▪ HIV▪ Malaria ▪ Rubella ▪ Toxoplasma Moving into molecular QCs…

12 Standards Unit  Writes and co-ordinates consultation and distribution of SOPs and algorithms with NHS (AMM, CVN, IBMS, ACM)  Looks after Technical Adverse Incident Reporting Sam Gillanders – Standards Unit

13 13 Technical Adverse Incidents Close liaison with MHRA, companies and users June

14 Standards Unit SOPs – current position 68 clinical microbiology 35 food water and environmental 50 media 37 guidance notes Sam Gillanders – Standards Unit

15 15 Historical background Standard methods first produced in 1996 BSOP 9 Throat swab SOP (1 st ) BSOP 28 Genital Tract SOP first issued in 1998 Revised in 2002 Re-issued in December 2003

16 16 Process Draft SOP SCBM Working Group Standards Unit 1st draft for comment 2nd draft for comment SCBM Working Group Final version

18 18 Need for a broad based approach to health protection 2002

19 19 HQ Network of 46 PHLs in 8 Groups CPHL CDSC What network of laboratories? HPA

20 20 BSOP 28 Investigation of genital tract and associated specimens

21 21 Our discussions with users Genital Tract SOP How much do people like the SOP? Do they use them? How? What do we need to change?

22 22 BSOP 28 Investigation of genital tract and associated specimens Break-down of 47 labs surveyed

23 23 BSOP 28 Investigation of genital tract and associated specimens The vast majority liked: introduction well referenced useful as benchmarks when labs merge force for improving quality benchmark for evaluation of new methodologies

24 24 BSOP 28 Investigation of genital tract and associated specimens However a few did not like: perceived cost implications length of some of the SOPs some disagreed with recommendations some methods are long winded, so broad they are ambiguous too much emphasis on clinical background

25 25 BSOP 28 Investigation of genital tract and associated specimens

26 26 BSOP 28 Investigation of genital tract and associated specimens

27 27 Genital Tract SOP Questions GC – when and how TV – when and how Anaerobes – when and how BV – when and how Gp B Streps – when and how

28 28 BSOP 28 Investigation of genital tract and associated specimens Blood agar Sabouraud agar GC selective agar Trichomonas media Target organisms HVS ** S. aureus Lancefield Groups A, C and G streptococci yeasts Urethral swab/ Cervical swab *** S. aureus Lancefield Groups A, C and G streptococci yeasts N. gonorrhoeae Clinically suspected TV STD Pregnancy * T. vaginalis

29 29 BSOP 28 Investigation of genital tract and associated specimens Media used MSOP 5 recommends NYC: GC selective + amphotericin (Nb VCNT + nystatin less effective) Do you culture HVS or ECX swabs for GC?

30 30 BSOP 28 Investigation of genital tract and associated specimens Which specimen do you examine for Trichomonas vaginalis? We recommend HVS, not ECX

31 31 BSOP 28 Investigation of genital tract and associated specimens How do you process the specimens for TV? We recommend culture but recognise that microscopy/wet prep may be more practical

32 32 BSOP 28 Investigation of genital tract and associated specimens Target organismsMediaClinical details Anaerobes Neo FAA agar with with MZ 5ug disc Intra-uterine death Septic abortion Miscarriage When do you look for anaerobes? We recommend culture depending on clinical details

33 33 BSOP 28 Investigation of genital tract and associated specimens Which specimens do you examine for anaerobes? We recommend culture depending on clinical details

34 34 BSOP 28 Investigation of genital tract and associated specimens Media used for isolating anaerobes We recommend FAA+neomycin (MSOP 4)

35 35 BSOP 28 Investigation of genital tract and associated specimens Do you look for Bacterial vaginosis? 24/47 said ‘Yes’

36 36 BSOP 28 Investigation of genital tract and associated specimens Do you culture and report Group B streptococci from HVS or ECX swabs? We recommend Gp B Strep may be important from either specimen

37 37 BSOP 28 Investigation of genital tract and associated specimens

38 38 BSOP 28 Investigation of genital tract and associated specimens A new SOP is being produced (SU in conjunction with RSIL and HPA Forum) Investigation of Screening swabs for Group B streptococci 1 st draft SOP to be discussed at the next WG meeting 15 June Your comments will be invited

39 39 Your help is needed!

40 Access to HPA SOPs Global access Over 1000 passwords issued for the Extranet site Password requests from 48 countries outside of the UK

41 41 National Standard Methods Close working with the Inspector of Microbiology Involvement and logos on front pages: ACM (not logo yet) AMM CVN IBMS ? SGM ? Other professional groups National SOPs

42 42 Where do standard methods fit in? SOPs Decision to collect specimen Type of specimen Specimen collection method Transport Time/Storage Variation in reporting Interpretation of result by clinician Decision how / whether to treat

43 43 Acknowledgements Thanks to Jerry Skinner, Ruhi Siddiqui, Janet Norcup, Sam Gillanders and all who responded to the telephone survey Also thanks to Keith Perry and Joe Vincini www.hpa.org.uk www.evaluations- standards.org.uk
