Specimen Preparation

  • Centrifuge within 1 hour, separate supernatant and refrigerate
  • Transport to laboratory as soon as possible
  • Avoid excessive light exposure. Protection is sufficient if kept in closed, dark container (refrigerator, transport bag). If this is not possible, and light exposure is expected to exceed 4 hours, please protect from light by wrapping in foil or other similar product.

Reasons for Rejection

  • Gross hemolysis
  • Not received at proper temperature
  • Not received within specified time frame
  • Wrong collection tube


For patients >15 days of age. If performing microtainer collection (capillary collection) please submit 2 tubes due to large number of tests requested. One single gel barrier tube may not contain sufficient sample volume to complete all testing. Transport whole blood immediately to the Lab due to limited glucose stability. A Direct (Conjugated) and Indirect (Unconjugated) Bilirubin will automatically be ordered if the Total Bilirubin is greater than 1.0 mg/dL. The extra testing will be performed at an additional charge and will generally not need an extra specimen.
