Blood Gases, Venous - Syringe

Chemistry

​Specimen Requirements​

  • ​Whole blood
​Container
  • Preferred Collection Container: Syringe (calcium and electrolyte balanced)

​Collection Procedure

    (Submitting the minimum volume makes it impossible to repeat the test or perform confirmatory/reflex testing. In some situations, a minimum volume may require a second collection.)
​Stability/Storage
