  • The Department of Microbiology aims to provide clinically relevant information to its users through the provision of a timely, accurate and reliable scientific service with clinically appropriate advice.                           

    The Consultants offer clinical advice and access to broader clinical consideration through Departmental Meetings and Multidisciplinary meetings.

    Consultants offer 24 hour advice for urgent cases. The Consultants normally visit the wards regularly.    Scientific Staff offer a 24 hour diagnostic service for urgent cases.

    Antimicrobial Drug Level Monitoring

     

    Gentamicin and Vancomycin levels are now performed by Clinical biochemistry department.

    Results are available on PAS (if requested via PAS) as soon as authorised.

    For other antibiotic levels, discuss with Microbiology consultant

    Gentamicin

    • Pre dose taken just before dose is given.
    • Post dose taken 1 hour after dose administered.
    • Normal range: Pre <2.0 mg/l, Post 5-10 mg/l

    NB. Gentamicin may be given once a day (OD). Here only one level is required - taken 12-18 hours after the dose is given. The level - called a random level (as the time is collected anytime after 12 hours of the dose given) is reported accurately to one decimal place.

    • Normal range for random levels:
    • <2.0 mg/l if 14 hours post dose
    • <1.0 mg/l if 24 hours post dose

    Vancomycin

    • Pre dose taken just before dose is given.
    • Post dose is not normally required.
    • Normal range: Pre 5-10 mg/l, Post (if performed) 20-30 mg/l
