Collect blood into a red-top vacutainer; avoid hemolysis. Allow the sample to clot. Centrifuge the sample; separate the serum from the cells and transfer to a leakproof, labelled tube. Refrigerate or freeze and ship with freezer packs. Lithium-heparin plasma is acceptable, however laboratory reference intervals are for serum samples.Additional Information
Phenobarbital (M to Sa). K Bromide (M,W,F). Due to the long half-life of potassium bromide, timing of serum sample collection is not critical once steady state levels have been achieved. Phenobarbital peak serum values are obtained at 4 hours post-pill. Trough serum values are obtained prior to administration of medication (pre-pill).
