Teicoplanin assay

Microbiology

Notes

  • These tests are referred to a Regional Reference Centre
  • Teicoplanin levels are non-urgent investigations and efforts should be made to avoid routine testing (and sampling) at weekends.
  • If necessary, assays can be arranged for Saturday mornings and most Bank Holidays, but must be received by the Microbiology Department at GRH by 10.00 am. Please telephone the laboratory to inform us that such a sample has been taken, requires testing and to confirm transport arrangements for the sample to the Microbiology Department at GRH
  • There is no service available on Sundays

When to test

  • The initial pre-dose assay sample should be collected just before the dose given on the 5th day. If this falls on a Sunday, the sample can be taken as planned and should be sent to Pathology Specimen Reception on the Sunday for dispatch for testing on the next working day
  • If a patient is on a prolonged course of teicoplanin (>2 weeks) and the initial levels are satisfactory, repeat levels should be monitored weekly
  • Otherwise, the Consultant Microbiologist will advise on repeat sampling, if indicated

Result interpretation

  • Results are reported with a standard interpretative comment that gives the recommended target (normal) levels
  • If there is any doubt regarding interpretation, contact the Consultant Microbiologist
