If the patient has a white blood cell (WBC) count of >50,000, for chemistry testing that includes potassium, the sample should be collected in a gold serum separator (SST) tube and not a Lt green plasma separator (PST) tube.

Immediately follow collection, mix sample by inverting 8 - 10 times to prevent clotting
