Doctor's Notes
Reviewed by Dr Pasupathy Arumugam — MBBS, MD (Pathology) · Reg. No. 21521
"Vancomycin levels must always be interpreted together with the patient's renal function and clinical picture. Target trough concentrations may differ based on the site and severity of infection."

Test Parameters & Specifications
Sample Stability
- Sample not collected in the appropriate SST tube.
- Insufficient sample volume below 1 ml serum.
- Delayed transport without appropriate refrigeration or freezing.
Understanding Your Results
The infection may not be adequately treated; a dose adjustment may be required.
Level: Below therapeutic target
Current dosing is likely appropriate; continue therapeutic drug monitoring as advised.
Level: Within target range
There is an increased risk of nephrotoxicity and ototoxicity; the physician may hold or adjust the dose.
Level: Above target or toxic range
If you have fever, chills, cough, shortness of breath, severe headache, nausea, vomiting, diarrhea, abdominal pain, or muscle aches, consult a doctor promptly. If you are already on vancomycin and experience hearing changes, dizziness, or reduced urine output, seek medical advice immediately.
Limitations
- ⚠A vancomycin test alone does not diagnose the infection.
- ⚠Results should be interpreted in the context of clinical status, renal function, and the specific infecting organism.
- ⚠Target ranges may vary by hospital protocol and infection severity.
Risks & Considerations
- ●Minor pain or discomfort during blood collection.
- ●Slight bruising at the puncture site.
- ●Light-headedness or fainting in rare cases.
- ●Very rare risk of infection at the needle site.
Interfering Factors
- ●Concurrent aminoglycoside therapy can increase the risk of toxicity.
- ●Renal impairment significantly affects vancomycin clearance.
- ●Time of sample collection relative to the last dose affects interpretation; trough samples are usually preferred.
