Collection Instructions Fingerstick specimens: can be falsely elevated due to skin contamination; venipuncture is preferred for sample collection. First wash the draw site with soap and water, then dry thoroughly with a clean towel (not a recycled paper towel). Disinfect the draw site with isopropyl alcohol; do not use an iodine containing disinfectant. Use powderless gloves.

Whole blood or plasma: Use only a EDTA containing Navy blue top (trace metal free) vacutainer for collection. Navy blue top vacutainers are available from the Clinical Labs in room M521 (Moffitt Hospital).

Do not use a plastic syringe to collect the specimen: the black rubber seals of the syringes contain varying amounts of contaminant metals.

24 hour or random urine: Collect the sample directly in the acid-washed container obtained from Specimen Receiving. Do NOT use a metal bedpan or urinal. If an acid-washed container has not been supplied by the reference laboratory it must be prepared, using only devices made of polyethylene or polypropylene with metal-free plastic caps. Fill the device with a solution made from equal parts of metal-free 6N nitric acid (HNO3) and metal-free deionized water and let it stand for 30 minutes. Use ONLY nitric acid. Then rinse the containers or pipettes with 5 volumes of metal-free water to remove metal and acid
residues.
