Comments:
Blood gas analyses and calculations assume a patient temperature of
37°C unless the laboratory is informed of a different temperature
either by phone or by paper documentation if sample is hand-
delivered. Any air drawn in with the sample must be expelled
immediately. Samples that contain greater than 25% air to sample
volume ratio will not be analyzed. All needles must be removed from
the syringe before delivery.
