However, current research indicates more thought needs to be given when drawing specimens. The following laboratory tests: glycemia, azotemia, alkaline, Phosphatase, SGPT, bilirubin, amylase, GGT, chlorine, troponin I, CK-MB and platelets showed no value changes when drawn from the central line with different waste volumes or drawn peripherally. Also, the values did not change if the catheter was flushed with 5ml or 10 ml of NSS prior to obtaining the specimens. Alternatively, drawing specimens for LDH, calcium, potassium and white blood count showed significant discrepancy between a central line draw and obtaining peripherally (Cicolini). Further research would be necessary to determine if larger waste volumes had an effect on laboratory values. The study also does not indicate if the patient was receiving continuous infusion via the Central
