Preferred Sample Type



Specimen Volume

0.2 mL blood


Gentamicin, vancomycin, amikacin & tobramycin assays are available routinely. Other antibiotics may occasionally require monitoring – this should be discussed with the Clinical Microbiologist.

This test is performed by Clinical Biochemistry.

A GREEN request form must be completed to avoid delays in testing


The results for these assays are available on the Browser immediately after testing. Results are usually available within 24 hours of receipt.

Clinical advice is available via extension 16516 or 16537 during normal working hours or via switchboard at other times.

Information on antibiotic treatment (all the prescribed antibiotics, dosing regimens and sampling times) and the age of the patient must be supplied on the request form; otherwise interpretation of results will be difficult.


Full information on the appropriate monitoring of antibiotics can be found on the UHB Trust website, (link below). Alternatively, a guide is available through the Help menu in PICS.



For users outside the UHB Trust please refer to your local guidelines.
