Specimen Stability
Additional Specimen Instructions
Peak levels should be drawn 60 minutes after IM injection, or
30-90 minutes (30 minutes optimal) after the end of IV
administration over 15-90 minutes.
Samples for antibiotic therapeutic drug monitoring are ideally
drawn via peripheral venipuncture. When peripheral venipuncture is
not possible refer to DH procedure ID 234 for guidance on
appropriate collection site and steps to adequately flush the
catheter/line. Subcutaneous ports (e.g. Mediports) should be
avoided for sample collection due to a high risk of sample
contamination.
